    The decibel (dB) is a unit of measurement that is frequently used to measure the intensity of sound. The higher the decibel measurement, the louder the noise; but it is not a completely straightforward scale. A sound that is 50dB is going to be more than twice as loud as a 25dB noise. This somewhat exponential increase continues along the scale
