During the UCL/LDL procedure, at what starting dB level should testing begin?

In the UCL (Uncomfortable Loudness Level) or LDL (Loudness Discomfort Level) testing procedure, it is standard practice to begin testing at 70 dB. This starting level is chosen because it is generally considered to be around the threshold where most individuals perceive sounds as comfortably loud.

Beginning at this level allows for a systematic approach to identifying the point at which sounds become uncomfortable for the listener. The choice of 70 dB as the starting point balances the need to ensure that the subject is engaged and responsive while also avoiding initial levels that might be too loud for comfort, thus keeping the test within safe and effective parameters.

Progressing from this starting point, the testing will increase in volume to pinpoint the exact threshold at which discomfort begins, helping audiologists and dispensers to customize hearing solutions for their clients' needs.
