What is the normal hearing range represented by 0-25 dB HL?

The range of 0-25 dB HL (decibels Hearing Level) is considered to reflect normal hearing ability. Individuals within this range typically have the capacity to hear sounds across a wide spectrum of frequencies without difficulty. This means that they can effectively detect soft sounds and are generally able to communicate and interact with their environment without experiencing challenges associated with hearing impairment.

By contrast, any hearing loss that falls outside this range, such as moderate, severe, or profound, would fall into thresholds above 25 dB HL, indicating varying levels of difficulty in hearing soft sounds and normal conversations. Thus, categorizing 0-25 dB HL as normal hearing is crucial for understanding the health and functionality of an individual's auditory system. This classification is fundamental in audiology when assessing and diagnosing hearing loss.
