Question

Two sounds are emitted from the same source. If the ratio of their loudness is 1:9, what will be the ratio of the amplitudes​

Answer 1

Answer:

Accordingly, the relative intensities of two sounds in bels is equal to the logarithm of the intensity ratio—i.e., if I is the intensity of one sound and I0 is that of another, then the intensity ratio B in bels is B = log10 (I/I0). The unit in general use is the decibel (abbreviated db), equal to 0.1 bel.
