Sound propagation
A disturbance in the medium sound travels through
Rarefraction
An area where the displaced particles in a medium are spread out
Compression
An area where the displaced particles are closer together
Elasticity
A medium's tendency to resist change and return to its original state
intensity of sound
Perceived as loudness- related to the density of compressions and amplitude of particle
vibration
Frequency
Perceived as pitch- the rate of compressions and rarefactions per second (Hz)
Wavelength
Distance covered by one complete cycle of a sound wave. High frequency= short
wavelength; low frequency = long wavelengths
noise cancelling
Tones that are out of phase are used to cancel sounds
Baffle
An obstacle to sound energy that can either absorb, reflect, refract, or diffract the sound
energy
Reflection
The bouncing back of a wave when it hits a surface through which it cannot pass.
Absorption
When sound energy is dissipated as heat
Sound shadow
an area of reduced sound intensity around the ear farther away from where a sound
originates
Diffraction
Scattering of energy around a baffle
Refraction
When a sound is forces to change its direction of propagation because of a change in
speed as it passes through a baffle
0 dB HL
Sound pressure level needed for the average person with normal hearing to detect a
test signal 50% of the time
Pitch
