Short clinical test lengths amplify response variability into inaccurate loudness curves.

Evidence

The ISO recommendations (Kinkel 2007 ) for adaptive CLS testing are designed to constrain the test time to a duration that is clinically acceptable. Due to the relatively low number of experimental trials, the natural variability of responses can create an inaccurate CLS function. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2516

The ISO recommendations (Kinkel 2007 ) for adaptive CLS testing are designed to constrain the test time to a duration that is clinically acceptable. Due to the relatively low number of experimental trials, the natural variability of responses can create an inaccurate CLS function. Our proposed ML estimation approach is inspired by the work of Green ( 1993 ), who developed a technique for using estimation theory to determine the psychometric function of a “yes-no” task. We modify and extend this concept to estimate the MCPF that best describes an individual listener’s categorical loudness perception. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2516

• QUESTION: Chain worth tracing: how does trial count quantitatively scale the CLS error, and where is the accuracy floor under fixed clinical time budgets?
