Suppose that the sound level of a conversation is initially at an angry 72 dB and then drops to a soothing 50 dB. Assuming that the frequency of the sound is 507 Hz, determine the

(a) initial and

(b) final sound intensities (in Î¼W/m2) and the

(d) final sound wave amplitudes (in nm). Assume the speed of sound is 345 m/s and the air density is 1.21 kg/m3.
