The pain threshold of sound level is 120 db 160 db O 140 db

The following five problems should be calculated on paper, scanned or photographed, and submitted for credit. Convert the following sound pressures to sound pressure levels: p = 20 Pa p = 1 Pa p = 2 x 10-5 Pa Convert the following sound pressure levels to sound pressure: Lp = 80 dB Lp = 15 dB

Which statement about how the pitch of a sound is determined is accurate? neuromast cells in different parts of the middle ear respond to different sound frequencies sensory neurons in the tympanic membrane fire action potentials at the appropriate frequency regions of the basilar membrane with shorter, stiffer fibers vibrate more with high frequencies sensory neurons lining the inner walls of the cochlea send action potentials at the same frequency which they vibrate

In a pig-calling contest, a caller produces a sound with an intensity level of 107 dB. How many such callers would be required to reach the pain level of 120 dB?
