a) The sound level of a jet at take o is 140 dB, while the level of a normal conversation is 50 dB. What is the ratio of the intensities of the sound level of the jet versus the level of normal conversation?

b) What is the loudness of a jackhammer (in use) if it is known that this sound has an intensity 10 times that of sound due to heavy city traffic (90 dB)?

The difference in two sound levels, Bi and B2, in decibels (dB), is given by the logarithmic equation B2 - B1 = 10log where is the ratio of their intensities.
