The comprehensive Sandlin's Textbook of Hearing Aid Amplification, now in its third edition, provides the hearing health professional with an overview of the technological advances related to hearing aid devices. The authors give particular emphasis to the most current advances in clinical assessment techniques and hearing instrument technology, and provide a detailed analysis of the application of digital signal processing. Clinical insights into the psychology of hearing health are included to help professionals meet clients' emotional as well as acoustic needs. This is a valuable text for academic and clinical professionals involved in the selection and fitting of hearing aid devices for the acoustically impaired.

New to the Third Edition

  • Updated chapters on earmold and earshell acoustics; principles and applications of high-fidelity amplitude compression; and microphone technology
  • Major revisions to chapters on digital signal processing; hearing aid selection, fitting, and verification; mathematical formulae for applying amplification; measures of validity and verification; and surgically-implanted hearing devices for unilateral hearing loss
  • Discussion of distribution methods; considerations for treating children; elements of design and implementation of DSP circuits; the evolution from analog to digital hearing aids; and future consideration for the field

This text is regularly used by clinicians at the graduate level of training in the 70 to 90 universities offering graduate degrees in audiology. Furthermore, practicing clinicians in countries all over the world have included this recognized text in their professional libraries.

Douglas Beck spoke with Michael Metz about the legacy of Robert Sandlin and the new edition of this classic book. Read the full interview here.


"The editor has assembled a superb set of authors representing industry, academia, and clinical practice. In the Introduction, the editor describes the revised organization, which partitions the 20 chapters into five major sections: (1) historical overview; (2) acoustics as it relates to speech, amplification, and coupling; (3) digital signal processing (DSP); (4) selection and fitting of hearing aids; and (5) expanded treatment of hearing-aid fitting, outcome measurement, and combining hearing aids with other devices. Common to each chapter is an initial outline and a summary section, and most chapters include review questions to facilitate integration and consolidation of the information presented. 

A number of the chapters have been updated substantially, including those on earmold/earshells, DSP, microphone technology, and pediatric amplification with new chapters on real-ear measures and unilateral hearing loss. In total, the material reflects recent advances in advanced signal processing, feedback management, microphone technology, and wireless communication."
