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 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.
