The intensity of sound is measured on the decibel scale, dB. The equation dB=10log I represents the decibel level, where I is the ratio of the sound to the human hearing threshold. A noise registers a decibel level of 29. Which equation could be used to find how many times greater the noise is than the human hearing threshold.
