What is pitch of a note?
Pitch is the frequency at which an object vibrates to create a sound. A tuning fork, for example, that vibrates 440 times a second will produce a perfect "A" note. It is these predetermined levels of frequencies that pitch is categorized into the twelve chromatic musical tones.
Does a High pitched sound has a high number of partial tones?
Not neccessarily, pitch depends on the fundamental frequency. The number of partial tones is independent from fundamental frequency, and, roughly speaking, determines the timbre of the sound (through variables like spectral balance, for example).
How are loudness of sound and wave interference related?
As you know, sound travels in the form of waves with crests and troughs (high and low points). When two waves meet, constructive or deconstructive interference can occur. Loudness increases when waves interfere constructively, in other words when crests combine with crests or when trough combine with troughs to produce an even larger wave amplitude (the height of the resulting wave). Loudness decreases when waves interfere deconstructively, in other words when crests cancel out troughs to produce a smaller wave amplitude.
Why is there a change in sound tones as a car moves by?
There are changes in the frequency of the sound waves caused by the motion of the car, which demonstrates the Doppler Effect.
What is the relationship between frequency amplitude and pitch?
Wavelength = (speed of sound) divided by (frequency) Frequency = (speed of sound) divided by (wavelength) Amplitude is not related to frequency or wavelength. A change of amplitude does not cause ... and does not result from ... a change of frequency or wavelength
Does an ambulance siren's pitch really change - what if the ambulance was stationary?
Modern electronic sirens change amplitude and pitch. Older sirens produced tones that changed in amplitude (volume) but were changed in pitch by their motion relative to the listener: increasing in frequency as they approached and decreasing in frequency when they moved away. This is called the Doppler Effect.
What are the 3 principle characteristics of musical tones?
-- Amplitude (loudness) -- Frequency of fundamental / (mathematically tied to wavelength) -- Timbre/distortion (number and amplitudes of harmonic components) How about -- Attack ? -- Decay ? -- Vibrato ?

What is the theory of hearing that the rate of auditory nerve impulses matches the frequency of tones?
Frequency Theory
What is the tone of a single frequency called?
Sounds consist of fundemental tones and overtones. A single frequency is a fundemental tone.
Why can't adults hear high frequency ring tones?
Bacause they can't
What is the difference between FSK and ASK?
Both are digital modulation types for radio, transmitting data as two states usually. Amplitude shift keying varies the amplitude of the carrier, and often is used to switch the carrier on or off for the two states. Frequency shift keying varies the frequency of the carrier, so it is one of two distinct frequencies. These can be seen as digital versions of AM and FM.With amplitude shift keying the detector needs to distinguish between the two levels, which can vary widely due to propagation. Some sort of gain control or automatic threshold adjustment is needed, and noise bursts can be misinterpreted as data. This method tends to be simpler to implement, but less reliable than other modulation types (more prone to interference).Frequency shift keying is more or less constant amplitude so the interference (which is mostly AM in nature) is better suppressed. Frequency stability can be an issue with narrow band UHF radios.---ASKAudio Shift Keying - Digital signals are sent by modulating a carrier using an two or more tone audio tone. This is generally used for single sideband transmissions, but since it is an audio signal it can be used on FM/PM/AM.FSKFrequency Shift keying - Digital signals are sent by changing the frequency of an amplitude UN-modulated signal and decoding it using a side-tone receiver to reproduce the tones. FSK can be sent by any mode which has a carrier.
Why can't adults hear high frequency ring-tones?
because their ears are more developed.

What did Hubble do with the Doppler Effect?
he used it to find out the diffetrent tones and frequency in things that pas by like a train horn first its at a high frequency then into a low fruequency
Which signaling method carries tones in the same voice frequency and circuit of a telephone call?
in-band signaling
What is dual-tone multi-frequency dialling?
Dual-tone multi-frequency dialing refers to the fact that when a non-rotary phone dials, it sends two tones at the same time. When these tones are put together, a distinct sound is created, which is recognized by the switch at your phone service provider.
