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
Perceived as loudness- related to the density of compressions and amplitude of
intensity of sound particle vibration
Frequency Perceived as pitch- the rate of compressions and rarefactions per second (Hz)
Distance covered by one complete cycle of a sound wave. High frequency= short
Wavelength wavelength; low frequency = long wavelengths
noise cancelling Tones that are out of phase are used to cancel sounds
An obstacle to sound energy that can either absorb, reflect, refract, or diffract the
Baffle 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
