The decibel (dB) is defined as dB =101og, where P2 is the

The decibel (dB) is defined as dB =101og, where P2 is the power of a particular R signal and P is the power of some reference signal. In the case of sounds, the reference signal is a sound level that is just barely audible. How many ds does a sound have if its power is 7,320,000 times that of the reference sound? Round to the nearest tenth. 29.8 dB 10.0 dB 68.6 dB 0.0 dB 158.1 dB
