What average dB threshold at 2, 3, and 4 kHz indicates recordable hearing loss?

The average dB threshold at 2, 3, and 4 kHz that indicates recordable hearing loss is established by recognizing the criteria used in audiometric testing. A threshold of 25 dB or greater signifies that a person's hearing is impaired compared to the normative data, which is vital for determining whether a hearing loss record should be documented.

This specific threshold is significant because it reflects the level at which sounds become difficult for individuals to perceive, impacting their ability to communicate effectively and engage in everyday activities. Sound levels above this threshold suggest a decline in hearing function that warrants further evaluation or intervention. Thus, using 25 dB as a benchmark for recordable hearing loss is aligned with the standards set forth in both military and civilian hearing conservation programs.
