threshold of hearing

The threshold of hearing is the faintest sound level that the average person can detect under ideal conditions. It varies across different frequencies, meaning we are more sensitive to certain pitches than others. This threshold is measured in decibels (dB), with 0 dB representing the quietest sound detectable by most people. Factors like background noise or hearing health can affect this threshold. Essentially, it marks the point where sound becomes perceivable, serving as a baseline for understanding hearing sensitivity across the range of human hearing.
