The Nature Of Sound Flashcards
A physical environment in which phenomena occur
Medium
A measure of how high or low a sound is perceived to be, depending on the frequency of the sound wave
Pitch
An observed change in the frequency of a wave when the source or observer is moving
Doppler effect
The extent to which a sound can be heard
Loudness
The most common unit used to measure loudness
Decibel
A reflected sound wave
Echo
The process of using reflected sound waves to find objects
Echolocation
The combination of two or more waves that results in a single wave
Interference
The explosive sound heard when a shock wave from an object traveling faster than the speed of sound reaches a person’s ears
Sonic boom
A pattern of vibration that simulates a wave that is standing still
Standing wave
A phenomenon that occurs when two objects naturally vibrate at the same frequency; sound produced by one object causes the other object to vibrate
Resonance
The result of the blending of several pitches through interference
Sound quality
A sound that consists of a random mix of frequencies
Noise
A longitudinal wave that is caused by vibrations and that travels through a medium
Sound wave
