auditory function and balance Flashcards
sound: explain frequency, pitch, intensity, volume and the decibel scale
1
Q
define frequency
A
measured in Hertz: 1 cycle per second
2
Q
define pitch
A
perception of frequency
3
Q
define timbre
A
what distinguishes 2 sounds at the same frequency and intensity (e.g. flute vs violin)
4
Q
define sound intensity
A
amount of energy delivered per second (J/s/m2)
5
Q
what defines the sound level, what is this, and what is given if this is x10
A
Bel scale, which is the logarithms of sound intensity; if x10, becomes decibel scale
