Recent developments in hearing aid technology and earmold acoustics have improved the outlook for the hearing impaired. Advances involving the electric microphone, integrated circuit, and earmold/hearing aid coupling system have affected such features as compression amplification, filtering, and frequency characteristics of the amplified signal at the eardrum. The resulting changes in hearing aid fitting approaches are described, including factors which are considered in such fittings as in-the-ear, binaural, CROS and BICROS, with examples of difficult cases. Hearing aids are then discussed in the context of a broader rehabilitation strategy.
