What type of hearing loss ranges from -10 to 15 dB?

Normal hearing is characterized by a hearing threshold ranging from -10 to 15 dB. This range indicates that an individual can hear sounds at very low levels, which is considered typical for hearing sensitivity. It signifies that the individual is able to detect and understand spoken words and soft sounds without difficulty, placing them within the normal hearing range.

The thresholds above and below this range help categorize various degrees of hearing loss. Moderate hearing loss, slight hearing loss, and severe hearing loss reflect varying degrees of diminished auditory sensitivity, but they do not apply to thresholds within the normal range of hearing, which is specifically defined as up to 15 dB. Understanding these distinctions is crucial in hearing health and audiology, as they guide the fitting of hearing instruments and the management of hearing preservation strategies.
