To be safe and effective OTC hearing aids (HAs) need appropriate output limits. For existing HAs, limits are routinely specified as the OSPL90 sound level. We will describe three bases on which to recommend an OSPL90 limit of 120 dB SPL (2-cc coupler) for OTC devices: (a) values from current HAs with different power levels, (b) the recently developed Consumer Technology Association standard for PSAPs, and (c) analysis of the European Union standard for personal music players and associated headsets.
