Decibels provide a relative measure of sound intensity. The unit is based on powers of 10 to give a manageable range of numbers to encompass the wide range of the human hearing response, from the standard threshold of hearing at 1000 Hz to the threshold of pain at some ten trillion times that intensity.
waves is measured in units of decibels (dB), as shown in Figure 13. The softest sound a person can hear has an intensity of 0 dB.Normal. conversation has an intensity of about 50 dB.Sound with intensities. of about 120 dB or higher are painful to people.
