Types Hearing aid styles may be broadly classified as “standard” and “custom.” Standard hearing aids include behind-the-ear (BTE), mini-BTE, and receiver-in-the-canal (RIC) devices. These products are designed to fit most ears and usually require some customization of the earpiece and the connection of the device to the earpiece. Custom hearing aids include in-the-ear (ITE), in-the-canal (ITC), and completely-in-the-canal (CIC). These products require a custom-molded shell that houses the electronics. Standard and custom hearing aids come in a variety of colors, shapes, and sizes. (AAA, 2011)
The choice of hearing aid styles and features is based on several factors including the exact type and degree of hearing loss, your individual needs (such as communication requirements, lifestyle, and manual dexterity), and your medical and audiological history and related findings.
If both ears need amplification, your audiologist will recommend two hearing aids. Research has shown that two hearing aids provide superior benefits for the majority of people with regard to better word recognition in quiet and noisy backgrounds, better quality of sound, better localization ability, more natural hearing. Research has also shown that when both ears are candidates for hearing aids and only one ear is fitted, the unaided ear may lose speech recognition ability more rapidly than the fitted ear.

After your hearing aids have been selected, they must be fitted appropriately. Hearing aids must amplify sounds so they can be heard comfortably without causing discomfort, and hearing aids must be secure and physically comfortable in the ear. The hearing aids are adjusted using a computer in the audiologist’s office, and the results can be measured. However, the audiologist’s office does not usually represent the variety of sounds heard in everyday life, and so your new hearing aids will need to be evaluated in the sound environments important to you; a daily journal is useful for this purpose. By working with your audiologist, the hearing aids can be adjusted to perform most functions optimally and automatically in these environments. Your audiologist will likely suggest specific hearing assistive technologies to supplement the hearing aids and to address specific complaints. (AAA, 2011)
Maintenance and Insurance
Your audiologist will review with you the details of your insurance coverage (if available), financing options, loss, theft and damage insurance, warranty, service protocols, maintenance advice, as well as introductory periods and return policies.
As with all electronics, hearing aids require care and maintenance. This includes handling them carefully, not exposing the hearing aids to water and chemicals, and keeping them very clean. Your audiologist will discuss and demonstrate proper daily care as well as maintenance techniques and maintenance products. The hearing aid user’s manual will review many of these same points. Given the hostile conditions (temperature extremes, high levels of humidity, ear wax, etc.) under which hearing aids operate, daily cleaning and maintenance is recommended. Proper care and maintenance clearly reduces the need for repair. (AAA, 2011)
Expectations and Outcomes
Even with the best technology, it is important to maintain realistic expectations. While hearing aids make sounds easier to hear, they will not restore normal hearing. Hearing aids re-introduce you to a world of sound, and it takes time to become accustomed to the new sounds. Some people adjust quickly, others take longer. Your audiologist will discuss auditory training programs, communication strategies, and hearing assistive technologies to alleviate difficulties in these situations.
Untreated hearing loss impairs memory and may cause difficulty related to learning new tasks. Untreated hearing loss may result in decreased job performance and has been shown to negatively impact wages and earnings. Hearing loss treated with hearing aids has been shown to decrease fatigue, irritability, risk to personal safety, and withdrawal from social situations. Further, in many research studies, hearing aid use has been shown to increase the wearer’s quality of life. (AAA, 2011)
