Threshold of Sound

The threshold of sound is the quietest level of noise that a person can typically hear in a calm, gentle environment. It represents the minimum sound intensity required for our ears to detect a sound, usually measured in decibels (dB). For example, this threshold is around 0 dB, which is the faintest sound a young, healthy ear can perceive, like a whisper or rustling leaves. It varies between individuals and can be affected by factors like age or hearing health. Understanding this threshold helps in assessing hearing abilities and diagnosing hearing loss.
