Comparing MPOs from Six Different Hearing Aid Manufacturers: Headroom Considerations

Using 2-cc coupler measures, MPO values for different programmed settings were compared for the premier hearing aid products from six major manufacturers. Large differences were observed, and these differences were not directly associated with the product’s OSPL90. In general, at least for the sample audiogram used, it appears that the MPO is limited by the gain setting and the aggressiveness of the wide dynamic range compression (WDRC), often restricting useable headroom.

Real World Evidence on Gain and Output Settings for Individuals with Mild-to-Moderate Hearing Loss

Based on the audiograms of over 28,000 adults, this study shows that commercially-available hearing aids programmed according to parameters typical of those used for individuals with mild-to-moderate hearing loss yield output and gain levels that are well within the recommended limits (110 dB SPL output and 25 dB gain) specified by a recent Consensus Paper issued by the four national professional organizations representing hearing healthcare providers.

Clinical Speech Audiometry in the Age of the AERP

True listening involves more than just repeating words. Might there be useful ways to think about quantifying listening effort by taking advantage of a considerable body of research on the auditory event-related potential (AERP)? In this article, Dr James Jerger explores two different ways to think about clinical speech audiometry relative to assessing total listening effort: 1) Altering the task from repetition to decision, and 2) Evaluating the response evoked by the decision via an AERP paradigm.
