The decibel (or dB) is the unit of intensity used to describe hearing sensitivity. During a diagnostic hearing evaluation the threshold is measured at different frequencies (or Hertz, Hz) in each ear. The degree of hearing loss is expressed by the difference between a person’s threshold and the average threshold for people with normal sensitivity.

Understanding the decibel scale will give you insight into the degrees of hearing loss, and help when it comes to hearing protection. Human ears can detect an incredibly wide range of sounds. We measure sound intensity on a logarithmic base 10 scale , which proceeds in multiples of 10, rather than on a linear scale.
