Part Description

LP266543-0   Hearing threshold
The hearing threshold is the lowest intensity level at which a sound at a specific frequency can be heard. Intensity is proportional to sound pressure and is related to the perception of loudness, while frequency is related to the perception of pitch. In audiology, intensity is often expressed in the unit of measure decibels of hearing level (dB HL), which is a ratio of the measured sound intensity to a reference sound intensity value.
