Ear-drum reference point measurements are clinically risky and unreliable at high frequencies
Evidence
The procedure is time-consuming and uncomfortable for the subject with the risk of causing damage to the ear drum. These measurements are rarely performed except in clinical research settings. Another challenge is the measurements are notoriously unreliable at high frequencies where small changes in microphone position can produce 10–20 dB differences. — Toole, Floyd E, Sound reproduction- the acoustics and…, 1736
