Recall from Section 0.5 that the loudness of a sound indecibels (dB) is given by = 10
Chapter 3, Problem 38(choose chapter or problem)
Recall from Section 0.5 that the loudness \(\beta\) of a sound in decibels (dB) is given by \(\beta=10 \log \left(I / I_{0}\right)\), where I is the intensity of the sound in watts per square meter \(\left(W / m^{2}\right)\)
and \(I_{0}\) is a constant that is approximately the intensity of a sound at the threshold of human hearing. Find the rate of change of \(\beta\) with respect to I at the point where
(a) \(I / I_{0}=10\)
(b) \(I / I_{0}=100\)
(c) \(I / I_{0}=1000\).
