The acoustic properties of the test signal must be defined clearly. An FM signal is best for assessing threshold of hearing. The examiner should measure the SPL and verify the spectral characteristics of the signal. The frequency of calibration measurements should be identical to that used for earphones, generally once every 3 months.

Hearing measurement 185 (LAeq,8h is the equivalent noise level for an 8-hour exposure when the exchange rate is 3 dB. 88 dB(A) for four hours equals 85 dB(A) LAeq,8h while 91 dB(A) for two hours is the same as 85 dB(A) LAeq,8h.) NIOSH defines hearing impairment as a pure-tone average in either ear for the
Real-Ear Measurements (REMs) - Hearing Tracker
https://www.hearingtracker.com/services/real-ear-measurements
Real-ear measurements (REMs) are used to verify the “correct” hearing aid volume is provided, while factoring in your unique hearing profile and ear canal resonance. This should be considered the starting point. From there, you may work with your audiologist to make additional tweaks based on your own sound preferences. Why are REMs performed?

A coupler measurement is the electro-acoustical analysis of a hearing aid connected to a coupler inside a sound occluded box known as a sound chamber. Coupler measurements are perhaps the easiest and the most convenient way to perform an independent verification of the response of …

It is critically important that audiologists use objective probe microphone real-ear measurements to verify the performance of the hearing aid in matching prescription targets. However, such techniques do not serve as a replacement for using speech recognition tests as measures of benefit in speech understanding.

to provide a measure of the aided hearing of the user, or the functional gain of the user's hearing aid(s). This function has largely been replaced by real ear measurement except in the case of special devices, such as bone-anchored hearing aids or cochlear implants, where such measures are not possible.
Guidelines for Manual Pure-Tone Threshold Audiometry
https://www.asha.org/policy/GL2005-00014/
Diagnostic standard pure-tone threshold audiometry, used most often in clinical settings, includes manual air-conduction measurements at 250, 500, 1000, 2000, 3000, 4000, 6000, and 8000 Hz (125 Hz under some circumstances) plus bone-conduction measurements at octave intervals from 250 Hz to 4000 Hz and at 3000 Hz as needed.
