Objectives: Clinical pure-tone audiometry is conducted using stimuli delivered through supra-aural headphones or insert earphones. The stimuli are calibrated in an acoustic (average ear) coupler. Deviations in individual-ear acoustics from the coupler acoustics affect test validity, and variations in probe insertion and headphone placement affect both test validity and test-retest …
Pure Tone Audiometry - an overview | ScienceDirect Topics

Hearing sensitivity within the speech frequencies is known as the pure-tone average (PTA) and can be calculated by adding the thresholds obtained at 500, 1000, and 2000Hz and dividing the result by 3. 11. For audiometric results to be valid, the patient must respond to stimulation of the ear being tested.
Guidelines for Manual Pure-Tone Threshold Audiometry
https://www.asha.org/policy/GL2005-00014/
Pure-tone threshold audiometry is the measurement of an individual's hearing sensitivity for calibrated pure tones. Three general methods are used: (a) manual audiometry, also referred to as conventional audiometry; (b) automatic audiometry, also known as Békésy audiometry; and (c) computerized audiometry.

In general, the ambient noise should not exceed 35 dB ( A) as measured with a calibrated sound level meter . If it is higher than this then it is recommended that audiometry

Pure tone audiometry indicates what hear-ing thresholds (dB) are required to just be able to perceive a tone at different frequencies (Hz). A pure tone audiology threshold at a specific frequency is the decibel level at which a sound is perceived 50% of the time. The decibel scale used in pure tone audiometry is dB Hearing Level (dB HL). The dB HL intensity scale is
