What is the range of decibels that defines a normal degree of hearing loss?

The range of decibels that defines a normal degree of hearing loss is 0 to 15 dB. This range indicates the threshold at which a person can hear sounds that are typically produced in everyday environments without any difficulty. Hearing within this range means that an individual can perceive sounds as they are intended to be heard without requiring additional amplification or support.

In general audiometric terms, a hearing loss is typically considered mild if it falls between 16 to 25 dB, and more significant losses are categorized with higher decibel ranges. Therefore, understanding that 0 to 15 dB represents normal hearing is crucial for identifying and addressing potential hearing impairments in individuals, particularly in the context of education for deaf and hard of hearing students.
