Hearing Aids and Their Fitting and Selection

Before you make your decision, it is helpful to have some background information on hearing aids and their fitting and selection. This article covers the process, instruments used, and the costs involved. The audiogram is a visual representation of your hearing loss, showing you the device you need.

For example, a person with conductive hearing loss may need a bone-anchored device, while a person with sensorineural hearing loss will likely need a more traditional hearing aid. In addition, someone with a more active lifestyle may need a device with more features. Visiting a Tinnitus Specialist Santa Monica will help determine your condition and guide you on the next steps.


In selecting hearing aids for patients, clinicians must carefully consider many factors. Not all hearing aids are equally effective, and there is no single best fitting for every patient. The clinician must consider the patient’s needs and goals, as well as the assessment of their hearing loss.

The first step in hearing aid fitting and selection is assessing your hearing condition. The audiologist will examine your ear canal and determine whether your hearing aid will fit comfortably. It should not cause any pain when you wear it. The second phase in the procedure is programming the hearing aid, which is often done when you make a Costco hearing aids appointment. Hearing aids are generally generic, but your audiologist will program them to suit your hearing loss and lifestyle.


Hearing aid fitting and selection involves identifying the factors that affect the quality of amplification and determining the best fit. Some of these factors include the microphone effect and directivity index. An excellent fitting process should also consider the environment in which the hearing aid will be used. For example, the degree of reverberation and distance can impact DI, as well as the angle and position of the listener relative to the sound source.

A standardized approach to hearing aid fitting is essential to ensure a comfortable fit and accurate sound output. Most dispensers follow guidelines based on the patient’s audiogram and auditory threshold. The most current standard of care involves using a probe microphone in the ear canal to accurately measure the hearing aid’s output parameters.

Physiological Factors

In addition to the clinical process, physiological factors must be considered when fitting hearing aids. For example, if a patient has a high degree of hearing loss, a device that does not work correctly can cause discomfort. If a patient has a high degree of noise sensitivity, a hearing aid with a mixed or conductive component may be best.

However, these findings only apply to some. They may depend on various factors, including the degree of sensory impairment and cognitive decline. One of the most common reasons for purchasing a hearing aid is subjective awareness of deteriorating hearing. Other cognitive resources impacted by hearing loss include visual and fine motor skills. Working memory and inhibitory capacity are two necessary cognitive resources that may differ between non-users and full-time users.

Anatomical Factors

There are a variety of anatomical factors that affect hearing aid selection and fitting. These factors can influence the choice of hearing aids for individuals of different ages and physical abilities. For example, agility, mobility, and hand size affect how hearing aids are inserted and removed. Additionally, a patient’s condition may affect tactile sensitivity.

A clinician must consider these factors when determining which type of hearing aids best suits a patient. The first step in the fitting process is determining the hearing loss the patient experiences. This is done through a comprehensive exam. This will involve a thorough exam of the ear canal and the eardrum. The clinician may also use a Needs Assessment Questionnaire.
