A beat is a variation in amplitude that occurs when two sounds waves with slightly different frequencies are played simultaneously. The rate at which the amplitude varies, known as the beat frequency, is equal to the difference between the two original frequencies. Beats can be used by musicians to tune their instruments by adjusting the frequency until the beating stops. The human ear can detect a frequency difference as small as 3 Hz for tones around 440 Hz. Playing a 440 Hz and 443 Hz tone together would produce beats with a frequency of 3 Hz, which is easily detectable by the human ear.

Learning Objects 7 - Beats and Beat Frequency
A powerpoint presentation of what beats are, and what beat frequency is in physics. It also explains how instruments are tuned.
Beat Frequency LO 8
Beat frequency occurs when two sounds waves of slightly different frequencies are combined, resulting in a fluctuating volume caused by the interference between the waves. The difference between the frequencies is called the beat frequency, which can be used to tune instruments by listening for beats. The beat frequency formula is fbeat= |f1 - f2|, where f1 and f2 are the frequencies of the two sources. An example problem demonstrates how to use the beat frequency to calculate the pitch of a piano note based on the number of beats heard when played with a tuning fork.
Beats Frequencies
Using multiple choice, my LO will help one how to calculate mean and beat frequency. A concert master determines how off the initial note was by counting how many beats is in a second.
Beats
Beats occur due to the interference of waves with different frequencies. To find the resulting beat wave, the principle of superposition is used to add the two waves together using a specific formula. Beats are important in music as varying the frequencies creates different genres by interfering waves. The beat frequency is the difference between the frequencies of the interfering waves. When this difference is small, a single combined wave is heard, but two distinct tones are heard when the difference is large.

Sound is produced by vibrating objects and travels as compressional waves through a medium such as air, which are sensed by the human ear. For sound to be produced, three things are required: a vibrating body, a medium such as air, and a receiver like the ear. Sound waves can be recorded and played back by converting vibrations to electrical signals that are stored and then used to recreate the original sound waves. The human ear can detect sounds between frequencies of 20-20,000 Hz.

Beats occur when two sounds waves with similar frequencies are combined. The frequency of the beats is equal to the difference between the frequencies of the two sound waves. If a violin player hears 2 beats per second while tuning a string, the untuned string's frequency must be 2 Hz lower than the reference frequency of 440 Hz. For two animals calling from land and water, the beat frequency is calculated to be 5.5 Hz based on the difference between their calculated frequencies.

noise
This document discusses analog communication and noise. It defines noise as unwanted energy that interferes with signal reception and reproduction. Noise is classified as either external noise generated outside receivers, like atmospheric or man-made noise, or internal noise generated within receivers, like thermal, flicker, and transit-time noise. Thermal noise is generated by random molecule motion, while flicker noise occurs at low audio frequencies in transistors. Transit-time noise arises during electron transit time in transistors at very high frequencies. Signal-to-noise ratio is the power ratio of signal to noise, and noise figure is the ratio of input to output signal-to-noise ratios of a receiver. Simple noise problems can be solved using the provided formulas.
13 nature of-sound
The document discusses the nature and physics of sound. It defines sound as oscillations of pressure transmitted through a medium like air, occurring at frequencies between 20-20,000 Hz. Sound travels in longitudinal waves that create alternating compressions and rarefactions. Forced vibrations occur when an object is made to vibrate by an external force. Resonance happens when successive impulses match an object's natural vibration frequency. Interference is the combined effect of overlapping waves, which can increase or decrease amplitude through constructive and destructive interference. The Doppler effect describes how the observed frequency of a sound wave is higher when its source is approaching and lower when receding.
Phys 101 lo #6
Beats occur when two sounds with similar frequencies are played together, causing the overall volume to increase and decrease over time. The frequency of a wave determines its pitch, while the amplitude determines volume. When two tones have a small frequency difference, such as 330Hz and 331Hz, beats will occur approximately once per second. But with a larger difference, like 200Hz vs 400Hz, beats are no longer present. Beats can be modeled mathematically using equations that describe the interaction of two wave amplitudes over time and position. Questions about beat frequency and number of beats in a time period can be solved using formulas involving the individual frequencies.
LO 7/8
Beat frequency occurs when two sounds waves of slightly different frequencies interfere. The beat frequency is calculated as the absolute value of the difference between the two sound wave frequencies. In the example provided, two tones of 230 Hz and 235 Hz are played together, resulting in a beat frequency of 5 Hz, calculated as the absolute value of 235 Hz - 230 Hz. While both Jessica and Simon used the correct formula, only Jessica accounted for the absolute value, making her answer correct. Beat frequencies above 30 Hz are heard as a tone, while those between 20-30 Hz are heard as beats. Lower beat frequencies down to 1 Hz can still be detected.
Sound 1
Sound is a form of energy that produces hearing in our ears. It is produced by vibration and travels as a longitudinal wave through compression and rarefaction regions in a medium. The Bell jar experiment showed that sound cannot travel through a vacuum. Sound waves are characterized by their amplitude, wavelength, frequency and speed. Pitch is determined by frequency of vibration and loudness by amplitude.
Sound wave for Dummies
This document discusses key concepts about sound waves, including:
1) Sound waves create regions of higher and lower pressure as they pass through a medium, compressing and stretching it.
2) The speed of sound depends on the medium and can be calculated using the bulk modulus and density of the medium.
3) A sound wave's wavelength depends on its frequency and speed, with the wavelength being shorter in denser mediums like water compared to air at the same frequency.
4) While wavelength can vary, the speed of sound is determined solely by properties of the medium like temperature, and is not affected by changes in frequency or wavelength.
Analysing sound waves
Sound is produced by vibrations traveling as longitudinal waves that require a medium. The document discusses how sound waves are produced by vibrating objects like tuning forks. It explains that sound waves cause alternating compressions and rarefactions in the propagation medium. Applications of sound waves are discussed, including using ultrasound for medical imaging and sonar. The document also covers how loudness and pitch of sounds are determined by amplitude and frequency of sound waves. An example problem is given about using echo time and speed of sound to calculate distance or depth.
Chapter 2 The Nature of Sound
1. Sound is caused by changes in air pressure that create sound waves. These waves have properties like amplitude, frequency, wavelength, and phase.
2. Frequency refers to the number of pressure change cycles per second and is measured in Hertz. Higher frequencies are heard as higher pitches while lower frequencies have lower pitches.
3. Harmonics are integer multiples of the fundamental frequency which determine the tone quality or timbre of different instruments and voices.
Sound, harmonics, frequency and pitch
This document discusses concepts related to music technology including sound, pitch, frequency, harmonics, equalization (EQ), synthesis, oscillators, sound envelopes, and filters. It explains that sound is pressure disturbances propagating through a medium, usually air, while pitch is the repetition rate of a sound determined by its fundamental frequency. It describes how EQ is used to boost or cut certain frequencies to alter tonal qualities. Synthesis and sound design are also covered, noting how oscillators, envelopes, and filters can be used to manipulate raw waveforms and create customized sounds.
Wave Theory
Sound is created by vibrations or waves that pass through matter and are detectable by the human ear. Waves have key properties including frequency measured in Hertz which is the number of times the wave repeats in a second, amplitude which is the strength of the wave measured from peak to centerline, and phasing which refers to whether the peaks and troughs of two waves are aligned or out of phase with each other. The human ear can detect frequencies between 20-20,000 Hz, with lower frequencies being omni-directional and higher frequencies being highly directional.

The document summarizes gear used for music production, including a Shure 8900 microphone and Yamaha Clavinova cvp 503 digital piano. It describes the Shure microphone's popularity, dynamic type, frequency response, and unidirectional pickup. It then explains how a dynamic microphone works using a diaphragm, coil, and magnet to create a current from sound waves. It also provides an overview of the analog-to-digital conversion process for recording, including sampling rate and bit depth, and the digital-to-analog conversion process for playback. Finally, it mentions that the Clavinova can record audio files in .wav format to a USB drive.
Learning objective -- Beats
Beats occur when two sounds waves of slightly different frequencies interfere with each other, causing the resulting amplitude to increase and decrease over time. The rate at which the amplitude oscillates between high and low volumes is called the beat frequency. The beat frequency is equal to the difference between the frequencies of the two interfering waves. For example, if a 100 Hz tone and 105 Hz tone are played together, their 5 Hz difference in frequency would cause the amplitude to beat at 5 Hz.
Mastering
The document discusses the process of mastering music, including defining mastering as tweaking the final stereo mix. It covers topics like the loudness war where increased compression is used to make recordings louder, new standards for measuring loudness like LUFS, considerations for dynamic range and headroom, tools used in mastering like compression and EQ, and the importance of monitoring on different systems when finalizing a track.
Hayley sinclair LO beat frequency
Two violinists play an open A note together but one tunes to 440 Hz and the other to 442 Hz. The audience would hear a beat frequency of 2 Hz as the sound waves from each violinist oscillate in and out of phase with each other, interfering constructively and destructively. An amplitude vs. time graph of the sound would show the waves starting in phase and becoming out of phase halfway through, illustrating the beating effect from the slightly different frequencies.
Relationship between string length, tension, and pitch

- Increasing the tension of a string increases its pitch. In the investigation, tension was increased by tightening the string.
- Decreasing the length of a string increases its pitch. On instruments like guitars, pitch is increased by pressing fingers further down the neck to shorten the vibrating length of the string.
- Pitch and frequency are directly related, with higher pitch corresponding to higher frequency. Frequency can be measured quant

The document discusses the neurological and psychological perceptions of sound. It explains that sounds can cause physiological responses and affect brain waves. It describes research showing that filtering and gating sounds through specialized processing can improve auditory functioning and skills by exercising the muscles of the inner ear. The concepts of resonance, entrainment, and sonic neurotechnologies are also introduced for intentionally applying sounds to bring about changes in the mind and body.Lo8
Two waves that are close in frequency, when combined, produce a beat pattern where the amplitude increases and decreases over time as heard by the human ear. Beats occur due to the interference created by two waves interacting, with the beat frequency equal to the difference between the two original frequencies. For example, two cellos slightly out of tune at 249Hz and 245Hz would produce a beat frequency of 4Hz.
Soundwaves
1) Sound is created by fluctuations in air pressure that propagate in the form of compression and rarefaction waves.
2) The properties of sound waves include frequency, wavelength, speed, and amplitude. Frequency determines the pitch of the sound, with higher frequencies corresponding to higher pitches.
3) The human ear can detect sounds between 300-3,000 Hz, which encompasses most of the frequencies that make up speech. The ear is most sensitive to these frequencies.
An Introduction to Audio Principles
This document provides an overview of sound and hearing, including:
1. It describes how the human ear works, from collecting sound waves through the outer ear and transmitting vibrations through the ossicles to the cochlea where hair cells detect different frequencies.

3. Wave interference and phenomena like resonance, standing waves, and the Doppler effect are also covered as they relate to the nature and perception of sound waves.
Sound - Physics
A wave is a repeating disturbance that transfers energy through matter or space. There are two main types of waves - longitudinal waves, where the matter moves parallel to the direction of the wave, and transverse waves, where energy is transferred without transferring matter. Sound is a form of energy caused by vibrations that transfers through longitudinal waves. Key properties of waves include wavelength, frequency, amplitude, and speed. Sound waves can interfere constructively or destructively and be reflected, refracted, or absorbed.
part 1 acoustic.pptx
Architectural acoustics deals with controlling sound in buildings by managing how sound is transmitted, absorbed, diffracted or reflected. The goal is to reduce unwanted noise and improve listening conditions. Proper design of acoustical spaces like theaters and auditoriums is important for evenly distributing sound without defects like echoes or dead spots. The size, shape and orientation of rooms, as well as sound-absorbing and reflective materials used in construction, impact a building's acoustical qualities. Architectural acoustics provides guidance to designers on room acoustics and achieving the optimal reverberation time for different types of spaces.

Signatures of wave erosion in Titan’s coasts
The shorelines of Titan’s hydrocarbon seas trace flooded erosional landforms such as river valleys; however, it isunclear whether coastal erosion has subsequently altered these shorelines. Spacecraft observations and theo-retical models suggest that wind may cause waves to form on Titan’s seas, potentially driving coastal erosion,but the observational evidence of waves is indirect, and the processes affecting shoreline evolution on Titanremain unknown. No widely accepted framework exists for using shoreline morphology to quantitatively dis-cern coastal erosion mechanisms, even on Earth, where the dominant mechanisms are known. We combinelandscape evolution models with measurements of shoreline shape on Earth to characterize how differentcoastal erosion mechanisms affect shoreline morphology. Applying this framework to Titan, we find that theshorelines of Titan’s seas are most consistent with flooded landscapes that subsequently have been eroded bywaves, rather than a uniform erosional process or no coastal erosion, particularly if wave growth saturates atfetch lengths of tens of kilometers.

Candidate young stellar objects in the S-cluster: Kinematic analysis of a sub...
Context. The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty objects requires an explanation for the detection of compact Doppler-shifted Brγ emission. The ionized hydrogen in combination with the observation of mid-infrared L-band continuum emission suggests that most of these sources are embedded in a dusty envelope. These embedded sources are part of the S-cluster, and their relationship to the S-stars is still under debate. To date, the question of the origin of these two populations has been vague, although all explanations favor migration processes for the individual cluster members. Aims. This work revisits the S-cluster and its dusty members orbiting the supermassive black hole SgrA* on bound Keplerian orbits from a kinematic perspective. The aim is to explore the Keplerian parameters for patterns that might imply a nonrandom distribution of the sample. Additionally, various analytical aspects are considered to address the nature of the dusty sources. Methods. Based on the photometric analysis, we estimated the individual H−K and K−L colors for the source sample and compared the results to known cluster members. The classification revealed a noticeable contrast between the S-stars and the dusty sources. To fit the flux-density distribution, we utilized the radiative transfer code HYPERION and implemented a young stellar object Class I model. We obtained the position angle from the Keplerian fit results; additionally, we analyzed the distribution of the inclinations and the longitudes of the ascending node. Results. The colors of the dusty sources suggest a stellar nature consistent with the spectral energy distribution in the near and midinfrared domains. Furthermore, the evaporation timescales of dusty and gaseous clumps in the vicinity of SgrA* are much shorter ( 2yr) than the epochs covered by the observations (≈15yr). In addition to the strong evidence for the stellar classification of the D-sources, we also find a clear disk-like pattern following the arrangements of S-stars proposed in the literature. Furthermore, we find a global intrinsic inclination for all dusty sources of 60 ± 20◦, implying a common formation process. Conclusions. The pattern of the dusty sources manifested in the distribution of the position angles, inclinations, and longitudes of the ascending node strongly suggests two different scenarios: the main-sequence stars and the dusty stellar S-cluster sources share a common formation history or migrated with a similar formation channel in the vicinity of SgrA*. Alternatively, the gravitational influence of SgrA* in combination with a massive perturber, such as a putative intermediate mass black hole in the IRS 13 cluster, forces the dusty objects and S-stars to follow a particular orbital arrangement.

Evidence of Jet Activity from the Secondary Black Hole in the OJ 287 Binary S...
Wereport the study of a huge optical intraday flare on 2021 November 12 at 2 a.m. UT in the blazar OJ287. In the binary black hole model, it is associated with an impact of the secondary black hole on the accretion disk of the primary. Our multifrequency observing campaign was set up to search for such a signature of the impact based on a prediction made 8 yr earlier. The first I-band results of the flare have already been reported by Kishore et al. (2024). Here we combine these data with our monitoring in the R-band. There is a big change in the R–I spectral index by 1.0 ±0.1 between the normal background and the flare, suggesting a new component of radiation. The polarization variation during the rise of the flare suggests the same. The limits on the source size place it most reasonably in the jet of the secondary BH. We then ask why we have not seen this phenomenon before. We show that OJ287 was never before observed with sufficient sensitivity on the night when the flare should have happened according to the binary model. We also study the probability that this flare is just an oversized example of intraday variability using the Krakow data set of intense monitoring between 2015 and 2023. We find that the occurrence of a flare of this size and rapidity is unlikely. In machine-readable Tables 1 and 2, we give the full orbit-linked historical light curve of OJ287 as well as the dense monitoring sample of Krakow.

- 1. Beats Prachyawanich (Daniel) Khotawanich L2M Blue 17444143
- 2. What is a beat • Constructive & deconstructive interference can be separated by intervals of time. • A beat is a variation in amplitude: increasing & decreasing as a function of time as one listens to two waves that have slightly different frequencies.
- 3. Beat • Rate of amplitude variation is proportional to the frequency difference. • When frequency difference is large, we hear the the sound as two distinct tones rather than one tone that varies in intensity. Sound waves start off interfering constructively (in phase) then when they are out of phase, they interfere destructively
- 4. Consider the following… • When two waves are close to each other in frequency, a tone that has a mean frequency would be heard, whose amplitude varies by the difference in angular frequency. • When two separate waves tones are not close in frequency, two separate tones would be heard.
- 5. Real life applications • When two separate tones are heard in a headphone, with one frequency in one ear and a different but close frequency in the other, we still hear beats even though the waves do not interfere outside of our head. This is known as BINAURAL BEATING. Resulting from the way our brain processes signals from our ears rather than from any interference of the sound waves travelling through the skull.
- 6. Real Life App. continued… • Beats can indicate if an instrument is out of tune where musicians are able to adjust the tune of their instrument by adjusting the frequency of its notes until beating stops.
- 7. Question • Consider the smallest change in frequency that the human ear can detect for tones that are played one after the other is 3 Hz for tones around 440 Hz. What beat frequency would you hear if you played a 440 Hz and a 443 Hz tone simultaneously?
- 8. Solution • The amplitude of the resultant wave would be modulated at 3 Hz. • A 3 Hz modulation is easy to detect. At 440 Hz, it is easy to hear beats with frequency differences as low as 1 Hz.
