ABSTRACT

Selecting appropriate custom in-the-ear amplification is a process of integrating shell and circuitry characteristics that satisfy what the patient wants and needs with what is physically and electroacoustically possible. Options are influenced by many factors, including ear anatomy, type and degree of hearing loss, medical conditions, lifestyle and an individual's capabilities and communication needs. This article provides a practical overview of criteria used in the selection of hearing aid type, shell construction, special features or accessories, and discusses the acoustic advantages of custom hearing aids.

KEYWORDS

Amplification - selection criteria - acoustic advantages of custom hearing aids - directional microphones
