What Is And How to Perform a Biological Calibration
https://www.shoebox.md/biological-calibration/
A biological calibration is a subjective test that starts with a physical examination of the audiometer and all accessories. It is meant to look for any signs of damage to any piece of equipment or accessory – including transducers, ear cushions, plugs, and cords. Specifically, you should check: For signs of wear or damage
BIOLOGICAL AUDIOMETER CALIBRATION CHECK

Biological audiometer calibration checks will be performed every day the audiometer is used. More frequent intervals (e.g., daily checks) may be required by the DoD component. Start a new form if a different listener is used and/or after the audiometer is re-calibrated. 1. AUDIOMETER. a. Manufacturer. Enter name of company that produced audiometer. b.

One of the important requirements for hearing evaluation is a calibrated audiometer. In the absence of the equipment (SPL meter with octave filter set, artificial ear with condenser microphone, artificial mastoid and Bruel & Kjaer equipment) required for calibration of audiometers, the audiologists and the otolaryngologists have to rely on biological calibration.

Each month an audiometer is in use, a biological calibration is required. This consists of testing a person having a known stable audiometric curve that does not exceed 25 dB @ any frequency between 250 and 6000 Hz and comparing the test results with the subject’s recorded hearing screening reference data.
