Frequency Lowering For All! – Is There Evidence for this Practice in Adult Fittings?
by Laurel A. Christensen, PhD
The manufacturer default settings for a hearing aid fitting are not always the most appropriate settings for the individual. Frequency lowering default settings are a good example, particularly since there has been an abundance of research interest in this area that can inform (impact?) clinical practice. In commercial hearing aids, one of two techniques is used: frequency compression or frequency transposition. Frequency compression is the more common technique.
Multi-Channel Compression: Concepts and (Early but Timeless) Results

While it is clear that improved technology and compression strategies have developed significantly over the last 15 years, this paper may still serve as a useful reminder of the limitations of simple multi-channel compression with short times constants.
