Normal hearing typically falls within what range of decibels?

Normal hearing is generally defined as the ability to perceive sounds within the range of 0 to 25 decibels (dB). This range reflects the threshold of hearing for most individuals, where sounds at or above 0 dB can be heard, and up to 25 dB is considered normal variation among different individuals. Some sounds in quiet environments might be at 0 dB, which corresponds to the quietest sounds humans can typically hear.

Those within the 0-25 dB range are generally able to hear most conversational speech and environmental sounds without difficulty, indicating healthy hearing sensitivity. Ranges above this, such as 25-50 dB, may indicate mild hearing loss, where individuals might begin to have difficulty hearing softer sounds or understanding speech in noisy environments. Therefore, recognizing that normal hearing typically falls within the 0-25 dB range is essential for audiologists and health technicians in assessing hearing health.
