Smaller step sizes in audiometry detect feigned hearing loss

Evidence

Note that using a smaller step size can be appropriate for audiometric testing, as the ascending runs will sample the psychometric function using the smaller step size. Of course, this procedure will take longer to implement and may result in different test-retest reliability. Such modifications are usually only implemented in the clinic under uncommon circumstances, such as when a listener is suspected of feigning hearing loss, either intentionally or unintentionally. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 311
