What is considered the normal hearing range in decibels (dBHL)?

The normal hearing range is defined as the threshold of hearing sensitivity where most individuals are able to perceive sounds without difficulty. The range of -10 to 25 dBHL represents the values considered normal for human hearing. This includes zero dBHL, which is the average threshold of hearing for young adults in quiet environments. Values below 0 dBHL can indicate heightened sensitivity to sound, while values up to 25 dBHL encompass the typical variation encountered in the general population.

Understanding this range is crucial for hearing assessments and the identification of hearing loss. Higher thresholds indicate diminished hearing ability, whereas values within this normal range suggest that an individual's hearing is functioning adequately. Recognizing these standards is essential for audiologists and hearing technicians in evaluating and diagnosing hearing capabilities.
