Audiology Practice Standards Organization Publishes Adult Hearing Aid Fitting Standard

NEW BRIGHTON, MINNESOTA – Audiology Practice Standards Organization (APSO) has published its second audiology standard, for fitting hearing aids to adult patients. The standard, S2.1 – Hearing Aid Fitting Standard for Adult and Geriatric Patients, is APSO’s second published standard since beginning operations in 2018.

This standard documents the professional work audiologists perform to determine candidacy, select, fit, verify and follow-up with adults patients receiving hearing aids. It may be viewed and downloaded on the APSO website

All APSO standards are developed by a group of audiologists who are experts in the area of  hearing aid fitting and are subject to second panel review, public comment, and further review by legal and ethics advisors prior to final approval and publication.

“This standard represents months of hard work by no less than a dozen published experts in hearing aid fitting. We are extremely grateful to everyone who participated in this tremendous effort. We are very proud to bring this long-awaited standard  to the profession of audiology and those interested in the high level of care provided by audiologists fitting hearing aids.” 

Tish Gaffney, AuD, 2021 APSO President

APSO is currently beginning work on additional practice standards for audiologists. Dr. Gaffney continued to note that “APSO spent considerable time and effort in the first year of operation to develop a rigorous process of standards development that includes multiple SME groups and  universal review by audiologists. This ensures that everyone in the profession has the  opportunity to comment on the standard before final publication. I hope that all audiologists  will look for standards to be opened for review and provide their own insight and expertise to  each and every standard that is within their area of practice.” 

APSO acknowledges the exceptional contribution of each subject matter expert (SME) who  participated in development of this standard. Two groups of SME volunteers are recruited for  all APSO standards.

Those volunteering to develop the adult hearing aid fitting standard  include: 

  • Jason Galster, PhD
  • Douglas Beck, AuD
  • Cynthia Hogan, PhD
  • Joscelyn Martin, AuD
  • Lindsey Jorgensen, AuD, PhD
  • Christine Ulinski, AuD
  • Ryan McCreery, PhD
  • Trent Westrick, AuD
  • Gus Mueller, PhD
  • Erin Picou, PhD
