The document discusses key concepts in acoustics including how sound is created, transmitted, and received through vibrations. It explains that sounds fade with distance as the vibrations lose energy. Reflection occurs when sound bounces back off a surface without being absorbed, while absorption converts sound waves to heat to reduce echoes and reverb. Isolation separates unwanted sounds when recording to focus on a single input. Reverb is the buildup of many reflections in a space, affected by the size and materials in a room. Echo is the repeated reflection of a sound until it loses energy, and decay time refers to how long it takes a sound to fade out in a space.

8 l sound & hearing (boardworks)
The document is about sound and hearing. It contains information on what causes sound, how sound travels through different materials at different speeds, and how the ear detects sound waves. It discusses key concepts such as amplitude and frequency, how they relate to the loudness and pitch of sounds, and experiments that can be done to measure the speed of sound and how it is affected by the medium. It also provides details on the human hearing range and mechanisms of the ear for detecting sound waves.
Light
Light is essential for vision but imperfect light can cause health issues and eye damage. There are various ways to measure light, including foot-candles, lumens, and lux. Good lighting is sufficient, uniform, and avoids glare or shadows. Natural light is better than artificial but artificial options include fluorescent and filament lamps. Standards recommend illumination levels of 100-2000 lux for different tasks. Good lighting criteria ensures proper illumination, uniform distribution without too bright light or flickering to prevent eye strain and accidents.
Acoustics
This document discusses acoustics and noise control. It begins by defining acoustics and describing the basics of sound, including properties like amplitude, frequency, wavelength. It then explains sound propagation principles such as reflection, refraction, diffraction and absorption. Different materials and their effects on sound are described. Noise control techniques like site planning, architectural design and sound barriers are discussed. Specific examples of architectural designs that enhance sound are provided.
Magazine Artical
The document discusses various concepts related to acoustics, including:
- Live rooms which bounce sound around in a pleasing way, such as auditoriums and bathrooms, versus dead rooms with high sound absorption like for recording vocals.
- Reverberation, which is the reflection of sound off surfaces that allows sounds to travel further and is used in theaters but can become "muddy" if excessive.
- Soundproofing, which reduces sound transmission between areas.
- Unwanted noise can be minimized through reducing electrical circuitry, editing out noise tails, and using windscreens for outdoor recording.
Lighting
Here are 3 tips for lighting different scenes:
1. For an internal scene use a key light as your main, a backlight to separate subject from background, and a fill light to lighten shadows.
2. For an external scene use available sunlight and supplement with reflectors. Choose a location with good existing light and face your subject towards the light source.
3. For night shoots use available moonlight or streetlights. Consider noise increase and use natural or considerable artificial sources like streetlights. Platforms can provide shadows.

Unit 2 illumination
Daylighting techniques like light wells, skylights, clerestory windows, and atriums can provide natural light and reduce energy usage in buildings. Various types of lighting fixtures use different light sources like incandescent, fluorescent, halogen, LED, and sodium vapor lamps. Calculating lighting needs involves factors like luminous flux, intensity, luminance, solid angle, and utilization factor to determine the number and placement of lamps required.
What is echo
An echo is the reflection of sound caused when a sound wave bounces off a surface back to the listener. For an echo to be distinguishable, the sound needs to travel at least 75 meters away from the source and back, taking over half a second. This is because sound closer than that distance will overlap with the original sound and not be a separate reflection. Examples of echoes include those produced by wells, buildings, and enclosed rooms.
Lumens & color rendering index
The document defines and provides examples for the terms lumens and color rendering index (CRI). Lumens is a measure of the total amount of visible light emitted by a source.

Finally, it defines binaural hearing and the differences between mono and stereo audio formats.
Lo1 article
The document discusses various acoustics principles and concepts related to indoor and outdoor sound recording. It covers how sound travels, different room types used for recording like live rooms and dead rooms, surface types that impact sound reflection and absorption, and challenges of outdoor recording like dealing with wind noise and ambient noise. It provides examples of techniques used to reduce unwanted noise, like using directional microphones, windshields, isolation panels, and positioning microphones away from noise sources.
What is sound
Sound is vibrations that travel through the air and can be heard when they reach an ear. Different rooms have different acoustics depending on the objects inside, with harder surfaces reflecting more sound. Music studios use foam panels on walls to absorb and break up sound instead of letting it bounce around the room. Reverberation is how long it takes sound to die out in a space, with open areas creating longer echoes than small, enclosed rooms. When recording outside, windshields help avoid wind interruptions and background sounds should be considered as unwanted ambience. Simulated acoustics are effects deliberately added to alter a room's natural acoustics.
Acoustics
1) Acoustics refers to vibrations that are audible to humans, ranging from 20-20,000 Hertz. All sounds originate from object vibrations.
2) Key characteristics of sound include requiring a medium to propagate, having a finite velocity, and traveling at different speeds in different materials. Sounds can be classified by pitch, timbre, and intensity.
3) Important factors that affect building acoustics include optimizing reverberation time, avoiding uneven loudness or focusing due to interference or resonance, and reducing echoes and noise. Absorbing materials and proper ventilation help address these factors.
Physics reverberation
Sound travels through reflection in auditoriums. Echoes occur when sound reflects off obstacles at a distance of at least 17 meters from the source. Reverberation, or prolonged sound, is controlled through sound absorption materials and curved ceilings and surfaces to distribute sound evenly throughout the hall.
Sound and more sound
Sound is produced by vibrations and travels as waves through a medium. Sound waves can reflect, diffract, and interfere with each other. The speed of sound depends on factors like temperature, density, and elasticity of the medium. Loudness decreases with distance from the source and is measured in decibels. Pitch is determined by frequency, and the Doppler effect changes perceived pitch for moving sources. Hearing works through the outer, middle, and inner ear, and hearing loss can be addressed using hearing aids that amplify sound. Ultrasound uses high frequency sound for applications like medical imaging and echolocation.
Acoustics I PPT.pdf
The document discusses key concepts in acoustics including:
1. Acoustics covers the properties and transmission of sound, and architectural acoustics applies these principles to buildings.
2. Important acoustic concepts include frequency, wavelength, amplitude, intensity measured in decibels, and reverberation.
3. A room's acoustics are determined by how sound waves propagate and are reflected off surfaces based on their material and shape.
4. Reverberation is the gradual decay of sound in a room after the source stops due to multiple reflections, and is measured by reverberation time.

sound and its property
This document discusses acoustics and the reflection of sound waves. It covers topics like reflection of sound waves from rigid and curved surfaces, reflection between different media, intensity of sound waves, reverberation time, echoes, and reducing noise in buildings. The key points are:
- Sound waves reflect in a similar manner as light waves, changing direction when reflecting off surfaces.
- Reflection depends on the properties of the reflecting surface and the media on either side.
- Intensity of sound depends on factors like amplitude, frequency, area of sound source, and distance from the source.
- Reverberation time is the time it takes for sound intensity to decrease by a million times after the source
Building Acoustics
Acoustics is the scientific study of sound, including how it behaves and is perceived. It deals with properties of sound waves like reflection, refraction, absorption, and interference. Acoustics is important for learning environments and other spaces where noise can be distracting or carry too much. Good acoustics involve distributing sound well, creating a sense of intimacy, and having proper reverberation times. Factors like reverberation time, loudness, echoes, and sound reflections off surfaces can impact architectural acoustics. A variety of materials like sound absorbers, reflectors, and diffusers are used to control sound.
Acoustics buildings
Acoustics is the study of sound waves and how they are generated, propagated, and received. When designing buildings, several acoustical factors must be considered, including reverberation, focusing of sound, echoes, unwanted resonance, interference, and extraneous noise. Reverberation is the persistence of sound after the sound source stops emitting sound, and the reverberation time depends on the size, surface materials, and absorption coefficients of the space. The Sabine formula relates reverberation time to the volume and absorption of a space. Proper acoustics in buildings ensures sound is uniformly distributed and factors like echoes, resonance, and interference are minimized.
Chapter 16
Sound is created by vibrations which move as longitudinal waves through a medium, transferring energy. The speed of sound depends on the temperature and density of the medium. Pitch is related to the frequency of the sound wave - higher frequencies have higher pitches. Loudness depends on the amplitude of the sound wave - louder sounds have higher amplitudes and more energy. Sound waves can interact through reflection, interference, and resonance.
Sound ppt
Sound is produced by vibration and travels as longitudinal waves, causing alternating regions of high and low pressure called compressions and rarefactions. The human ear detects these pressure variations and converts them into electrical signals that are sent to the brain for interpretation as sound. Sound waves have properties like amplitude, frequency, wavelength and velocity that depend on the medium and source of vibration.
Indoor and Outdoor Acoustics
Sound is a pressure wave that travels through air or other mediums and is perceived by humans and animals as hearing. It is produced when a medium such as air is set into vibration. Acoustics is the science of sound, including how it is transmitted and perceived. Recording studio acoustics aim to control the room environment to accurately capture sound without unwanted reverberation or leakage. Key aspects of studio design include soundproof live rooms, isolation booths, and absorbing surfaces and patterns on walls. Outdoor acoustic considerations include reducing wind noise, unwanted ambient noise, and ensuring the background atmosphere matches the intended recording.
Physiology of hearing.ppt
The document discusses the physiology of the ear and mechanism of hearing. It describes the anatomy and functions of the external, middle, and inner ear. The external ear collects sound and the middle ear, containing the ossicles, transmits sound vibrations through bone conduction to the inner ear. The inner ear contains the cochlea, which converts sound vibrations into nerve impulses via hair cells. These impulses travel along the auditory nerve pathway to the brain for interpretation and perception of sound.
Indoor and outdoor acoustics
1. Sound is the result of shifting air pressure over time and travels in the form of longitudinal waves through air. Acoustics is the science of sound and how it affects our lives through communication, music, and other applications.
2. A recording studio consists of a live room for performances, isolation booths for loud instruments, and a control room for equipment. Additional rooms include dead rooms which have little reverberation for clear vocal recordings.
3. Studio design aims to control sound through soundproofing techniques. Walls have patterns to absorb sound and prevent leakage. Reverberation and unwanted noise are also issues that studio design and equipment aim to mitigate for high quality recordings.
Sound - Acoustics & Psychoacoustics
Sound is defined as vibrations that travel through air or another medium and can be heard. It includes speech, music, and noise. Noise lacks a regular pattern and is considered undesirable sound. Sound is measured in decibels and can be recorded using microphones. The science of acoustics deals with the production, transmission, and effects of sound. It is divided into sound, which travels through fluids, and vibration, which is felt through denser materials. Psychoacoustics studies the relationship between the physical properties of sound and the sensations and perceptions they produce in human hearing.

Biggs rayner thomas pre production feedback ajo
Tom Biggs-Rayner blogged about his pre-production work for a music video on his blog. The teacher provided feedback on each pre-production task, finding Tom's work to be generally proficient with excellent details in some areas. The teacher suggested organizing the blog posts into clear sections and ensuring all text was easily readable. Overall the pre-production work was good but could be improved by adding proper storyboards. The teacher noted some improvements based on organizing the blog but adding labels could help navigation. The final mark was 14/20.
Biggs rayner thomas evaluation and overall feedback sheet
Thomas Biggs-Rayner received an overall grade of B for their A2 coursework. Their planning received a mark of 14/20 and their main construction task of creating a music video received high praise and a mark of 33/40 for creative use of technical skills. Their ancillary tasks of creating a digipak and poster received lower marks of 6/10 and 5/10 respectively due to a lack of creativity in the designs. Their evaluation received a mark of 15/20 for thoroughly answering questions about their video, ancillary products, audience feedback, and use of technologies.
Biggs rayner thomas production feedback
The music video received a high score due to excellent use of technical skills like camera work, framing, locations, props, and performance. It was well edited to match the beat of the song with good transitions between visuals. Overall, the video was a tongue-in-cheek homage that met the conventions of the genre and maintained audience attention through strong visuals and lip syncing. The digipak design showed awareness of conventions but images lacked creativity, while the poster also met some conventions but needed more original images and links to purchase.
Doc2
The document discusses the design choices for the cover of an album. The front cover uses a red background to represent the dangerous lyrics in the album and make it appealing to audiences. The back cover features a scene from a music video that viewers liked and continues the red tint theme. The inside cover advertises an upcoming event or song to provide free promotion since the genre is still small. A black theme is used throughout for continuity and to match the artist's public image of wearing black.
Doc2
The document discusses the design choices for the covers of an album. The front cover uses a red background to represent the dangerous lyrics in the album and make it appealing to audiences. The back cover features a picture from a music video that test audiences liked and keeps the red tint of the front cover but less intense not to distract from the song names. The inside cover advertises an upcoming album by Ocean Wisdom to help promote it as the genre is still small.
Date ryu
This document contains a shooting schedule for a music video with details about the dates, locations, actors, costumes, props, and equipment needed. It outlines that filming will take place between December 21st and January 15th in various locations in Bournemouth and Poulner. Various actors including Jonah Savage will be needed, with specific costume requirements listed for each scene. The Nikon D3200 camera, tripod, and steady cam will be used to capture footage, and After Effects and Premier Pro listed to edit the final video later in January.
Common sound chain
This document discusses sound equipment including speakers, microphones, and a sound desk. It provides details on:
- Active speakers have built-in amplifiers while passive speakers require an external amplifier. Speakers come in subwoofer and tops models of varying sizes.
- Microphones can be condenser or dynamic, with condensers being more sensitive but requiring phantom power. Wireless microphones transmit signal to a receiver.
- A sound desk allows adjusting input and output levels from various sources to mix and send sound through different outputs. It has channels, gain knobs, EQ knobs, auxiliary cables, and faders to control the sound.
- Amplifiers power electrical signals from the sound
Video chain input
The document describes the functions of a camera including recording images, live streaming, zooming, focusing, panning, tilting, white balancing, and effects. It then discusses using a vision mixer to select between multiple video sources and potentially mix them. A projector is used to project light and make a picture on a screen, allowing for a larger image than a TV screen. Rear projection allows projecting from behind a screen to have a more professional setup without seeing the projector. The camera setup for a talent show includes a static camera on a tripod platform to get a better view.
All production roles
The assistant stage manager has many responsibilities including assisting with props during rehearsals and running of the show, helping to move the set on stage during performances, managing backstage technicians, and training the running crew. They work closely with the stage manager, deputy stage manager, flyman, and sound technician.
Lighting equipment for Ringwoods got talent
This document provides information about various types of lighting equipment that could be used for a talent show called 'Ringwood got talent'. It discusses the power requirements and effects of PAR cans, CP lights, Fresnels, profiles and floor lights. PAR cans can produce a hot spot or halo effect, while Fresnels provide a soft edged beam. Profiles can zoom to make the lighting spot larger or smaller. Floor lights provide uncontrolled spill light over a large area. The document also shows images and descriptions of accessories that can be used with the different light types, such as barndoors, color gels, and color wheels.
Mics 2
A microphone transforms sound waves into electrical signals that can be amplified, transmitted, or recorded. Dynamic microphones do not require external power, while condenser microphones are more sensitive and require phantom power. Condenser microphones are generally better for acoustic instruments and quieter singers due to their extended frequency response and clarity over dynamic microphones. Dynamic microphones are better suited for louder inputs like screaming vocalists due to their ability to handle high sound pressure levels without distortion. Examples of good condenser microphones include the Neumann U87 and JTS-TX9, while a dynamic BETA 52A kick drum microphone is well-suited for capturing the kick drum. Various microphones, including condensers, are suitable for different
A2 music video information
The document provides details on the themes, concepts, locations, and shots planned for a music video. It will feature a main performer rapping in various urban locations around Ringwood and Poulner, including streets, a pool house, a pub, and a school. Shots will typically be 5-10 seconds and include the performer alone and with friends, changing outfits to match locations. Diagrams provide floor plans for specific scenes like rapping outside a car or being wrapped in cling film. Additional locations like flats in Southampton are suggested if needed.
Genre research
High Focus is a new UK hip hop record label established in 2011 in Brighton. It focuses on signing talented new artists in the UK hip hop scene. The label has seen some success, getting nominated for 'Best Small Label' at the AIM Awards. Popular artists on High Focus include Dirty Dike and The Four Owls. UK hip hop music videos typically represent the lower class experience and attitudes of anger towards authorities but also celebration of drugs and women. Elements like clothing, camerawork and lighting help convey the song's attitude and story.
Anotated digipack
The document analyzes and compares the visual styles of two UK hip hop artists' album packaging and promotional materials. It notes recurring themes like urban, gritty aesthetics with graffiti references and the use of distinct color palettes. Key details that help identify the artists and promote their music, tours, and brands are called out, such as prominent logos, dates, and images of the artists themselves. The analysis suggests design elements that effectively represent the artists' brands and music which could be applied to an original cover concept.
Ocean wisdom lyric anotate
The document appears to be lyrics from a rap song. It contains multiple verses of rhyming lyrics describing the artist's rapping ability and style. There are references to smoking, violence, and competing with other rappers. The lyrics are annotated with potential camera shots and visuals to accompany the song.
Music analysis on hip hop
This document analyzes elements of hip hop music videos over time from 1979 to the present day. It discusses conventions seen in early videos like Rapper's Delight compared to gangster rap videos of the 1980s. More recent UK hip hop videos are examined, noting techniques like matching shots to lyrics, using different angles and props. The document emphasizes developing a unique artist image and using camerawork, editing and effects to keep viewers entertained. It concludes that performance and a loose narrative are effective elements for the author's planned video to relate the song's meaning.
Question 2
The document discusses targeting audiences for gritty London crime dramas. It states that these films are usually rated 18 due to explicit content and drug use, and generally interest males ages 18-40. It suggests targeting social classes C2, D, and E as the location is in the backstreets of lower-class London. It discusses including violence and nonlinear storytelling from the start to draw in male audiences with lower attention spans. It proposes an all-male cast to connect with the male target audience and portray stereotypical media violence. Cockney accents and character names related to personalities are also suggested to emulate other successful London crime films.
Question 1
This document provides an overview and rationale for creative choices made in an opening scene and film. The opening scene is set in a caravan and introduces characters through freeze frames with voiceover bios. Conflict is established right away to draw in the target male audience. Camera angles are kept simple due to limited equipment. Minimal special effects and music are used to feel realistic like inspirational British "lad films." The title font is in bold army style with bullet holes to represent the action genre.

A.为什么留学生需要操作留信认证?
留信认证全称全国留学生信息服务网认证,隶属于北京中科院。①留信认证门槛条件更低,费用更美丽,并且包过,完单周期短,效率高②留信认证虽然不能去国企,但是一般的公司都没有问题,因为国内很多公司连基本的留学生学历认证都不了解。这对于留学生来说,这就比自己光拿一个证书更有说服力,因为留学学历可以在留信网站上进行查询!
B.为什么我们提供的毕业证成绩单具有使用价值？
查询留服认证是国内鉴别留学生海外学历的唯一途径但认证只是个体行为不是所有留学生都操作所以没有办理认证的留学生的学历在国内也是查询不到的他们也仅仅只有一张文凭。所以这时候我们提供的和学校颁发的一模一样的毕业证成绩单就有了使用价值。只硕大的蛇皮袋手里拎着长铁钩正站在门口朝黑色的屋内张望不好坏人小偷山娃一怔却也灵机一动立马仰起头双手拢在嘴边朝楼上大喊：“爸爸爸——有人找——那人一听朝山娃尴尬地笑笑悻悻地走了山娃立马“嘭的一声将铁门锁死心却咚咚地乱跳当山娃跟父亲说起这事时父亲很吃惊抚摸着山娃的头说还好醒得及时要不家早被人掏空了到时连电视也没得看啰不过父亲还是夸山娃能临危不乱随机应变有胆有谋山娃笑笑说那都是书上学的看童话和小说时多

Global Situational Awareness of A.I. and where its headed
You can see the future first in San Francisco.
Over the past year, the talk of the town has shifted from $10 billion compute clusters to $100 billion clusters to trillion-dollar clusters. Every six months another zero is added to the boardroom plans. Behind the scenes, there’s a fierce scramble to secure every power contract still available for the rest of the decade, every voltage transformer that can possibly be procured. American big business is gearing up to pour trillions of dollars into a long-unseen mobilization of American industrial might. By the end of the decade, American electricity production will have grown tens of percent; from the shale fields of Pennsylvania to the solar farms of Nevada, hundreds of millions of GPUs will hum.
The AGI race has begun. We are building machines that can think and reason. By 2025/26, these machines will outpace college graduates. By the end of the decade, they will be smarter than you or I; we will have superintelligence, in the true sense of the word. Along the way, national security forces not seen in half a century will be un-leashed, and before long, The Project will be on. If we’re lucky, we’ll be in an all-out race with the CCP; if we’re unlucky, an all-out war.
Everyone is now talking about AI, but few have the faintest glimmer of what is about to hit them. Nvidia analysts still think 2024 might be close to the peak. Mainstream pundits are stuck on the wilful blindness of “it’s just predicting the next word”. They see only hype and business-as-usual; at most they entertain another internet-scale technological change.
Before long, the world will wake up. But right now, there are perhaps a few hundred people, most of them in San Francisco and the AI labs, that have situational awareness. Through whatever peculiar forces of fate, I have found myself amongst them. A few years ago, these people were derided as crazy—but they trusted the trendlines, which allowed them to correctly predict the AI advances of the past few years. Whether these people are also right about the next few years remains to be seen. But these are very smart people—the smartest people I have ever met—and they are the ones building this technology. Perhaps they will be an odd footnote in history, or perhaps they will go down in history like Szilard and Oppenheimer and Teller. If they are seeing the future even close to correctly, we are in for a wild ride.
Let me tell you what we see.

ViewShift: Hassle-free Dynamic Policy Enforcement for Every Data Lake
Dynamic policy enforcement is becoming an increasingly important topic in today’s world where data privacy and compliance is a top priority for companies, individuals, and regulators alike. In these slides, we discuss how LinkedIn implements a powerful dynamic policy enforcement engine, called ViewShift, and integrates it within its data lake. We show the query engine architecture and how catalog implementations can automatically route table resolutions to compliance-enforcing SQL views. Such views have a set of very interesting properties: (1) They are auto-generated from declarative data annotations. (2) They respect user-level consent and preferences (3) They are context-aware, encoding a different set of transformations for different use cases (4) They are portable; while the SQL logic is only implemented in one SQL dialect, it is accessible in all engines.

【业务选择办理准则】
一、工作未确定，回国需先给父母、亲戚朋友看下文凭的情况，办理一份就读学校的毕业证【微信176555708】文凭即可
二、回国进私企、外企、自己做生意的情况，这些单位是不查询毕业证真伪的，而且国内没有渠道去查询国外文凭的真假，也不需要提供真实教育部认证。鉴于此，办理一份毕业证【微信176555708】即可
三、进国企，银行，事业单位，考公务员等等，这些单位是必需要提供真实教育部认证的，办理教育部认证所需资料众多且烦琐，所有材料您都必须提供原件，我们凭借丰富的经验，快捷的绿色通道帮您快速整合材料，让您少走弯路。

→ 【关于价格问题（保证一手价格）】
我们所定的价格是非常合理的，而且我们现在做得单子大多数都是代理和回头客户介绍的所以一般现在有新的单子 我给客户的都是第一手的代理价格，因为我想坦诚对待大家 不想跟大家在价格方面浪费时间
对于老客户或者被老客户介绍过来的朋友，我们都会适当给一些优惠。
选择实体注册公司办理，更放心，更安全！我们的承诺：客户在留信官方认证查询网站查询到认证通过结果后付款，不成功不收费！
