What should the quiet period baseline be before testing?

The quiet period baseline before testing, which is essential for ensuring accurate hearing test results, should be a minimum of 14 hours. This time allows for the reduction of any temporary threshold shifts due to noise exposure. When individuals are exposed to loud sounds, their hearing sensitivity may temporarily change, making it important to allow a sufficient recovery period before conducting an audiometric evaluation. A 14-hour quiet period helps ensure that potential fluctuations in hearing levels due to recent exposures are minimized, thereby providing a more accurate assessment of an individual's baseline hearing ability. This practice is essential for the effective monitoring of hearing conservation programs in occupational settings.
