What does the term 'dynamic range' refer to in audiology?

The term 'dynamic range' in audiology specifically refers to the difference between the threshold of hearing and the threshold of discomfort. This concept is important because it helps audiologists understand the range of sounds that a person can hear without discomfort. The threshold of hearing is the quietest sound that can be detected, while the discomfort level represents the point at which sound begins to become uncomfortably loud.

Understanding dynamic range is crucial for fitting hearing aids, as it influences how amplification is managed to ensure that sounds are made audible without crossing into uncomfortable levels. This is particularly relevant for individuals with hearing loss, as their dynamic range may be altered compared to those with normal hearing. The larger the dynamic range, the more sound levels a person can comfortably perceive, which significantly impacts communication and overall quality of life.
