Sound
Vibratory energy transmitted by pressure waves through a medium
Resonance
The natural tendency for an object to vibrate with great amplitude at one frequency than at
others when a driving force is applied
Frequency
Number of complete compression-rarefaction cycles per second
Pure Tone
Produced by simple repeated alternations of compression and rarefactions
Wavelength
The distance between one wave crest or trough to the next
,Rarefaction
When air molecules are less dense and spread further apart
Complex Wave
Acoustic combination of several different pure tones present simultaneously
Resonant frequency
The frequency at which an object vibrates with the greatest amplitude
Sound Pressure
The deviation from the ambient atmospheric pressure caused by a sound wave
Period
The time required for one complete cycle of compression and rarefaction
dB HL Reference
Audiometric Zero
Boyle's Law
States that as the physical volume that contains a gas decreases, the pressure of the gas
increases
Decibel (dB)
A logarithmic scale used to denote the intensity of a sound
Amplitude
The intensity of the energy of a vibrating body
Compression
, When air molecules are pushed together, making the molecular density greater than when at
rest
dB SL reference
Threshold
Phase
Describes the position in the cycle of one sound wave relative to another
Loudness
Psychological response to intensity
Pitch
Psychological perception of frequency
Critical bands
Represents the frequency resolution abilities of the ear
Intensity
Physical measurement that expresses signal amplitude
