  • Choosing Hearing Aids

It’s the easiest thing to believe that once you identify a hearing loss problem, all that is needed is the purchase of a hearing aid. We’d like to break that belief, in exactly six steps.

Dr. H. Gustav Mueller, founder of American Academy of Audiology, along with Dr. James Hall, renowned and awarded American audiologist, have described the right fitting of a hearing aid for adult patients with hearing loss through a six-step process.

First Step: Hearing Assessment

Any complaint of hearing loss has to be evaluated for its extent and its causes, with auditory and non-auditory considerations, in order to determine whether a patient qualifies for acquiring a hearing aid. This evaluation is best conducted by a certified audiologist.

Second Step: Treatment Planning

Once the diagnosis is established, a hearing aid would be recommended to increase the patient’s hearing potential. The treatment must focus on not only identifying the right hearing device, but also on enhancing the patient’s ability to communicate.

Third Step: Selection and Fitting

This is a thoughtful process. It relies on the fact that during the assessment of the hearing loss, more than just the auditory factors were taken into account. The patient’s degree of hearing loss, lifestyle and therefore battery requirements, external ear geometry and cosmetic concerns must be carefully  considered, to be able to recommend the optimal hearing device.

Fourth Step: Verification

It’s time to check if the hearing aid fits the patient, not just externally, but intrinsically. The soft sounds must be audible, speech recognition must be consistent or improved, and the loud sounds must be limited to a level of comfort.

Fifth Step: Orientation and Counselling

Hearing aid will definitely help in collecting sounds and sending them to the brain; but it does well to remember than there is also the task of getting accustomed to hearing in a new way, and communicating in a new way. This involves the patient, as well the family. With counselling, time is spent with the patients and their families, helping them adjust to amplified sounds. On an average, the patients require one and a half hour of counselling for the first two months after fitting process the hearing aid.

Sixth Step: Validation

The proof lies in measuring the difference in the patient’s life and the impact of the hearing aid towards this difference. This is an ongoing process, as it can be noted with every visit of the patient while using the hearing aid. It also includes re-programming or fine-tuning the hearing device as require, based on the patient’s feedback on preferred sound requirements.

David P Pascoe, PhD, audiologist and former professor at Washington University in St. Louis observed, “Although it is true that mere detection of a sound does not ensure its recognition, it’s even more true that without detection, the probabilities of correct identification are greatly diminished!” Therefore, it is essential to bridge the gap between a hearing problem and the correct hearing solution with a thorough and systematic approach, rather than a short-cut purchase of a hearing aid.
