Select the correct answer.
An audiometer is a machine that tests a person's hearing by producing tones across the speech spectrum. During a hearing test, an audiometer
produces a pure tone with a frequency of 2,000 hertz (cycles/second).
The given function represents the change in pressure, Plt), in millipascals, relative to the normal air pressure in the room as a function of time, t
in seconds, after the pure tone is produced.
p(t) = 2sin(4,000 7t)
What is the change in air pressure when the pure tone is produced?
OA 2 millipascals
ОВ. .
0 millipascals
OC. 1 millipascals
OD.
- 2 millipascals
