Document Summary
Cmd305 hearing science assignment 2c: suppose that, in this auditorium, you generate a high noise level and wait for it to die down. What is the reverberation time of the room? (hint: estimate the time to decay by 60 db by doubling the time taken to decay by 30 db. ) 5 seconds: you play two pure tones of approximately equal amplitude. 1010 - 1000 = 10 hz: interference and head shadow. A person is firing a shotgun held at the right shoulder. The person"s head has a diameter of 0. 2m. They would have hearing loss because of damage to the inner ear. The damage would effect the ear that was closest to the gun. Calculate the frequencies of the lowest order axial modes of an audiometric test suite that measures 1. 2 m x 2. 2 m x 1. 7m. Remember that you have three sets of parallel walls with different separations.
