ABSTRACT

Many hearing aid users require a period of time to adjust to new amplification or to changes in amplification; a process often termed auditory adaptation or acclimatization. This adjustment process can be related to the loudness levels of speech, changes in the spectrum of speech, environmental sounds, or other acoustic events. In many instances, a careful balance must be maintained between providing the patient with the appropriate gain and frequency response that will allow acclimatization to occur and at the same time avoiding hearing aid settings that will discourage the patient from using amplification. In this article we review several factors related to auditory acclimatization, illustrate how these factors relate to the features of today's hearing aids, and describe a software-based acclimatization procedure that can be easily implemented by dispensers in conjunction with popular prescriptive fitting procedures.
