Question

(a) What is the intensity in watts per meter squared of a just barely audible 200-Hz sound?

(b) What is the intensity in watts per meter squared of a barely audible 4000-Hz sound?

Answer 1

Answer #1

Solution (a) At 200 Hz, O phons 23 dB As 23 dB is twice (2.00) the intensity of 20 dE. Also, 20 dB=1x10-10W/m2. Thus, 1=(1x10
