![The pressures caused by pure tones on the eardrum are sinusoidal. The change in pressure P in pounds per square foot on a person's eardrum from a pure tone at time t in seconds can be modeled using the equation P = A sin (2xft+4), where f is the frequency in cycles
per second, and is the phase angle. When P is positive, there is an
increase in pressure and the eardrum is pushed inward, when P is negative, there is a decrease in pressure and the eardrum is pushed outward. A graph of a tone P(t) = .007 sin 2x(256.56)t +
