Open-fittings are very common with hearing aids and OTC devices. However, acoustic feedback often limits the usable gain, hence the audiometric fitting range. While manufacturers give some specifications about a device’s capabilities and limitations, there is no standardized benchmark for the performance characteristics of feedback suppression features as is done with other hearing aid characteristics. This project describes the validity of a proposed standardized method for quantifying feedback that can be used to guide clinical decision making and device selection.
