Building acoustics is the science of controlling sound in buildings by minimizing noise transmission between spaces. Characteristics of sound include reverberation time, echo, resonance, intensity, velocity, wavelength, timbre, amplitude, frequency, pitch, and loudness. Sound behaves differently with materials through absorption, diffusion, reflection, and transmission. Factors affecting building acoustics include geometry, volume, surface absorption/transmission/reflection, internal/external sound generation, and airborne transmission. Good building acoustics benefits health, productivity, privacy, intelligibility, and building value. Acoustic design incorporates absorption, diffusion, ceiling treatments, sound masking, and considers needs of different building types like residences, offices, schools,
The document discusses acoustics in buildings and sound insulation. It covers topics such as sound absorption, transmission, reflection, and insulation. Proper acoustical design includes considering site selection, volume, shape, interior surfaces, reverberation, seating, and absorption to achieve optimum sound quality. Sound insulation can be improved through rigid wall and floor constructions, double walls, resilient materials, and isolating noise sources. The acceptable noise levels for different building types are also provided.
This document provides details on designing an audio studio, including isolation, room treatment, and achieving target reverberation times (RT60). Key points:
- Three rooms will be designed - a control room, live room, and vocal booth. Standard room ratios will be used to minimize room modes.
- Isolation involves building rooms-within-rooms with mass, airtight construction, and decoupled structures. Brick walls, floating floors, sealed windows and doors will be used.
- Initial RT60 calculations show values much higher than desired 0.2s, 0.5s and 0.7s. Additional absorption materials like fiberglass and ceramic blankets will be added to walls, ceilings
Without sound masking, speech can be understood from up to 50 feet away. Sound masking reduces this distance to 15-20 feet or less, protecting employees from noises in surrounding offices while allowing communication over short distances. Research shows poor acoustics is the top cause of workplace dissatisfaction and reduced performance, as disruptive noises and conversations make tasks harder and more stressful. A sound masking system distributes background sound to mask unwanted noises and achieve privacy through speakers installed above ceiling tiles.
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.
How Acoustic Baffles Protect You from the Noisy Environment? sontext
Acoustic baffles help reduce noise and absorb sound, making homes and other spaces more relaxing. They are useful in environments like recording studios, conference halls, and churches that require sound absorption and noise control. Acoustic baffles and ceilings provide significant noise reduction from external sources like traffic or neighbors, allowing one to regain a peaceful environment without changing the outside noise. They have many benefits like allowing music composition or karaoke without disturbing others, maintaining silence in holy places, and creating ideal sound conditions in recording studios.
The document provides details about the Damansara Utama Methodist Church auditorium building. It discusses the building's history, design of the auditorium space, acoustic properties, and materials used. The auditorium has over 2300 seats arranged in a fan shape with staggered ceilings and uses various acoustic treatments and materials to optimize sound dispersion and absorption in order to function as a multi-purpose space for events like worship services and performances.

The document discusses various topics related to architectural acoustics including:
- The definition of architectural acoustics as the study of sound generation, propagation, and transmission in buildings.
- The importance of applying acoustic principles to improve quality of life through work and leisure environments.
- The need to both enhance desirable sounds like music, while reducing undesirable noise.
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.
- Sound is a form of energy produced by vibrating objects that travels in waves. The velocity of sound differs in various media like air, liquid, and solids.
- Frequency refers to the number of cycles per second and is measured in Hertz. A pure tone is a sound with a single frequency while complex sounds have multiple frequencies.
- Intensity measures the strength of a sound wave and determines its loudness, which is the subjective perception of intensity. Intensity is measured in decibels.
- Noise is an aperiodic complex sound that can be white, narrowband, or speech-related. Masking involves using one sound to render another inaudible.
1) Mono recording uses a single channel and microphone to record sound, which is played back through one speaker. This results in smaller file sizes but lacks stereo sound.
2) Stereo recording uses two channels to create a mirrored sound representation played back through two speakers. This allows for sound perspective and location.
3) Audio editing software like Logic and Audacity can be used to clean up recordings by removing unwanted noise and adding effects. A fixed or detached microphone can improve sound quality depending on the recording situation.
The document discusses the design considerations for auditoriums and recording studios. It addresses factors like room shape, size, absorption, diffusion, and reverberation time that impact acoustics. For auditoriums, a sloped floor and splayed walls can improve speech intelligibility. Absorption is placed in seating areas while keeping the stage reflective. Recording studios require low ambient noise and optimal reverberation. Room dimensions impact resonant modes so larger, irregularly-shaped rooms are preferred.

This document discusses building acoustics and provides solutions for acoustic defects. It begins with definitions and characteristics of sound, including transmission, absorption, reflection, and reverberation. Common acoustic defects like echoes, reverberation, insufficient loudness, sound foci, and dead spots are described along with solutions. Various acoustic materials are presented with applications and coefficients. A case study of a hotel demonstrates acoustic design considerations for reception, doors, furniture, ceilings, floors, and glazing.

End-to-end pipeline agility - Berlin Buzzwords 2024Lars Albertsson
We describe how we achieve high change agility in data engineering by eliminating the fear of breaking downstream data pipelines through end-to-end pipeline testing, and by using schema metaprogramming to safely eliminate boilerplate involved in changes that affect whole pipelines.
A quick poll on agility in changing pipelines from end to end indicated a huge span in capabilities. For the question "How long time does it take for all downstream pipelines to be adapted to an upstream change," the median response was 6 months, but some respondents could do it in less than a day. When quantitative data engineering differences between the best and worst are measured, the span is often 100x-1000x, sometimes even more.
A long time ago, we suffered at Spotify from fear of changing pipelines due to not knowing what the impact might be downstream. We made plans for a technical solution to test pipelines end-to-end to mitigate that fear, but the effort failed for cultural reasons. We eventually solved this challenge, but in a different context. In this presentation we will describe how we test full pipelines effectively by manipulating workflow orchestration, which enables us to make changes in pipelines without fear of breaking downstream.
Making schema changes that affect many jobs also involves a lot of toil and boilerplate. Using schema-on-read mitigates some of it, but has drawbacks since it makes it more difficult to detect errors early. We will describe how we have rejected this tradeoff by applying schema metaprogramming, eliminating boilerplate but keeping the protection of static typing, thereby further improving agility to quickly modify data pipelines without fear.

2. Why acoustic matters in restaurants
● Now a days restaurants have become very loud places
with a great of reverberation and echo.
● Both traditional and quantum acoustics have solutions for
creating quieter, clearer spaces with the ability to have a
decent conversation at a reasonable volume.
● One of the major hindrances created by poor acoustics of
a restaurant or any commercial space is making the
communication difficult.
● Customers would love the soft music and hustle bustle of
the restaurant, but due to the poor acoustics, the whole
surrounding can become an ugly noisy place.
● The poor acoustics will double the noise and customers
may found quite annoying.
3. THE FACTORS AFFECTING ACOUSTIC OF RESTAURANT
• Noise is one of the most common reasons for complaints, and today we can often see
restaurant reviews that include a noise rating in addition the rating of quality of food and
service
• The acoustic of the restaurant can affect the taste of the food . The theory suggest that
noise disrupts taste and smell, and it is found that the food tastes less intense in loud
noise ( 75 dB to 85 dB ).
• The main parameters that determine the
noise level in a restaurant are the volume,
reverberation time of the space and the
number of people.
4. THE COCKTAIL PARTY EFFECT
The ability of a normal hearing person to localize a sound source in the
surrounding 3D space , it is possible to focus on one out of many voices ,
and to focus on one voice out of many voices as they are suppressed as
background noise . This is so called cocktail-party effect. However, this
ability requires normal hearing capability and people using hearing aids of
older types may not be able to separate the voices in the 3D space.
VOCAL EFFORT
The vocal effort is characterized by the A – weighted SPL 1 meter in front of
the speaker. Normal vocal effort corresponds to an SPL around 60 dB at a
distance of 1 meter . By shouting, the SPL can reach 90 dB or more, whereas
in private communication (whispering or soft speech) typical levels are below
45 dB. The vocal effort depends on the situation, the distance to the people
being addressed, but also the type of the talk, e.g. private conversation or
giving a message.
5. The Lombard effect
In a noisy gathering, everyone raises their own voice in order to be heard better, which again
leads to a higher ambient noise level. This unconscious raising of the voice in a noisy
environment is called the Lombard effect. In quiet surroundings, the vocal effort is not
influenced by the ambient noise, but if the noise level exceeds 45 dB it starts to influence the
speech level. Interestingly enough, the Lombard effect is not particular to humans, but has also
been found in other mammals and birds.
Higher ambient level Louder conversations
6. The average relationship between speech level and ambient noise level is shown in the
graph below. . If the ambient noise is increased by 6 dB, the vocal effort is expected to
increase by 3 dB. The steps of vocal effort from relaxed to shouting are labelled in the
figure.
When enjoying a good meal in a restaurant and having a private conversation, the
ambient noise (including background music) should not exceed 55 dB, as this
corresponds to normal vocal effort. However, in a busy cafeteria, the ambient noise
can typically reach 70 to 80 dB, and a conversation is only possible in a loud or very
loud voice.
7. Ambient Noise Due To Speech
• The ambient noise in a room due to many people speaking simultaneously can be predicted
by taking the Lombard effect into account. The result is that the noise decreases by 6 dB if
the number of speaking persons is halved or if the reverberation time is halved.
• This may be a little surprising, because we normally have only 3 dB reduction of the noise if
the reverberation time is halved. So, adding more sound absorption to the room surfaces is
quite efficient; doubling the absorption area will also lead to a 6 dB reduction of the
ambient noise level with the same number of speaking persons.
• It has also been found that, in restaurants and banquet halls, the average number of
speaking people is the total number of people divided by 3 to 5 . You could say that the
average group size around each speaking person is between 3 and 4 people.
8. When listening to a conversation, the SPL of the voice should preferably exceed the SPL of the
ambient noise. The difference between these two SPLs is called the signal-to-noise ratio (SNR).
If the absorption area per speaking person is 25 m2
, the SPL is 65 dB both for the ambient noise
level and for the speech level at a distance of 1 meter. Thus SNR = 0 dB.
For normal-hearing people, it may be sufficient to have SNR = -3 dB, but in other cases this will be
clearly insufficient, namely in case of elderly people with reduced hearing capability or in case of a
conversation in a foreign language.
From the graphs, we see that SNR = -3 dB corresponds
to an ambient noise level of 71 dB. In order to obtain
an SNR = -3, the absorption area should be 12.5
m2
per speaking person. If this minimum of absorption
cannot be established, the acoustics must be
characterized as insufficient, and the total number of
people in the facility should be reduced.
9. Acoustic capacity
The fact that the acoustical conditions in a restaurant depends strongly on the number of
people present, has led to the concept called ‘Acoustic capacity’. This is defined as “the
maximum number of people allowed in a room for ‘Sufficient’ quality of verbal
communication”. Thus, the acoustic capacity is the number of people that can be expected to
create a SNR = -3 dB at a distance of 1 meter, and the corresponding ambient noise level of 71
dB . The acoustic capacity of a space depends on the volume V (m3
) and the reverberation
time T (s):
This shows that there are two ways to increase the acoustic capacity. Either the volume
should be enlarged, e.g. by opening to adjacent spaces, or the reverberation time
should be decreased by adding sound absorbing material to the surfaces.
10. The graph below shows the ambient noise level as function of the occupancy relative to the acoustic
capacity. The figure also shows the SNR at a 1 meter distance and the corresponding quality of verbal
communication.
11. An example is shown in the plan drawing below. This is a multi-purpose hall with high ceiling (17 m).
The volume is 12 920 m3
and the reverberation time is 1.5 s.
The figure shows the set-up for banquet for 240 people. The round tables are 1.6 m in
diameter and seat eight people each. Because of the high ceiling, there is sufficient
volume per person. The acoustic capacity is 430. With 240 persons the estimated
ambient noise level is 66 dB and the SNR at 1 meter distance is -1 dB, which suggests
‘sufficient’ quality of verbal communication.

12. Restaurants with one large dining room often have some of
the biggest problems with noise. That’s because sounds
tend to echo in these big rooms. Sound-absorbing hanging
baffles can dampen these echoes. Baffles are easy to
install: they only require S-hooks and lengths of chain or
wire.

17. Laminate Flooring Underlayment Acoustic Flooring Silent Flooring Underlayment
of Laminate Flooring. Common materials for acoustic flooring include
Acoustiblok, rubber based crumb, cork and felt for example.
Acoustic Flooring
Carpet or carpet tiles are known for mitigating impact sound, making them a
perfect choice for hotels, classrooms and offices. Higher pile carpets or
carpets with a thick pad underneath, are especially good at absorbing sound
and reducing transmission.
Combining carpet with resin flooring can help to insulate sound where you
need it most
18. Cork Flooring
Cork flooring is a sustainable, comfortable and sound-absorbent
flooring option perfect for many commercial applications. Still, due to
its tendency to stain and indent it is often used as an underlay to
provide acoustic insulation.
Wood Plastic Composite (WPC) Flooring
Durable, waterproof and easy to maintain, WPC flooring provides great acoustic
benefits, especially when it comes to mitigating the impact noise such as high
foot traffic. Its acoustic benefits are largely drawn from its backing layer, which
not only provides sound insulation, but also protects against mold and mildew.
Like acoustic plasterboard, acoustic plaster finishes have been around
for years.
Varying ingredients, compounds and systems can increase or decrease
weight and flexibility to further reduce surface reflections and in doing so
help with equalisation of the internal acoustics.
Acoustic Plaster
19. Rubber Flooring
Commercial rubber flooring is known for its sound absorbent
qualities. More than that, it is slip-, mold- and mildew-resistant. It
is a great choice for hospitals, schools, gyms and kitchens
looking for a durable acoustic flooring material. Rubber flooring
is known for its sound absorbent qualities as well as slip and
mold resistance
Vinyl Tile
Vinyl tile, especially luxury vinyl tile (LVT) installed with a
sound-insulating underlayment, is a great resilient flooring
option used for sound treatment. It is selected by many
facilities due to its design versatility, durability and relatively
low maintenance costs. LVT with sound-insulating
underlayment is a great resilient flooring option used for
