Tinnitus and hearing aids

A Legacy of Innovation and Inspiration

There exists a notable connection between hearing loss and tinnitus. In essence, the lack of external sound is replaced by internal perception of sound. However, this experience varies among individuals, as some with normal hearing may also encounter tinnitus.

Even if one isn’t aware of any hearing loss, it’s advisable to undergo a check-up, as the loss can occur gradually and unnoticed. Many individuals are surprised upon discovering they have hearing impairment.

It’s common for people to attribute their hearing difficulties to tinnitus rather than recognizing the underlying hearing loss. Upon identifying a hearing loss, the process of exploring solutions such as hearing aids can commence.

The primary goal of hearing aids is to address any hearing loss, with the expectation that this intervention may also alleviate tinnitus symptoms. Research indicates that wearing hearing aids consistently throughout the day yields the greatest benefits.

Bilateral hearing aids, worn in both ears, have demonstrated greater effectiveness compared to using only one aid.

The advent of digital hearing aids allows for more precise customization to individual needs, leading to an increased positive impact on tinnitus.
Even if individuals perceive their hearing loss as acceptable for their age, any hearing impairment causing difficulties should be addressed. Some audiology departments may recommend hearing aids even for mild hearing loss cases, often employing open-fit hearing aids for such instances.

About hearing aids

A hearing aid is a small electronic device worn in or behind the ear to amplify (or mask) sound for individuals with hearing loss

01
Open field

Open-fit hearing aids utilize a slender tube or a speaker positioned in the ear canal to convey sound, in contrast to traditional ear mould aids. This design enables amplification without obstructing external sounds or inducing discomforting occlusion effects, which were commonly associated with ear mould aids.
Occlusion effects occur when resonance builds up in the blocked ear canal, resulting in a sensation akin to having one’s head inside a barrel, particularly noticeable during speech or chewing.

02
Mixed devices

Certain hearing aids incorporate a sound generator feature, which, alongside amplifying external sounds, emits low-level sounds to mitigate the intrusiveness of tinnitus. However, the efficacy of this approach has not been definitively established.
Studies involving a limited number of participants have been conducted, but further research is necessary to differentiate the added benefit of sound generation from that solely provided by amplification. The findings of one study suggested that for the majority of participants, amplification alone led to a reduction in tinnitus annoyance.

03
Maintenance

Regular maintenance is essential for the proper functioning of all hearing aids. Ear wax and moisture can affect many hearing aids, although some are equipped with a protective invisible waterproof coating. Your provider will offer guidance on how to maintain your hearing aid.
Incorrect fitting of a hearing aid, resulting in either over-amplification or under-amplification, can lead to issues. Consulting with an audiologist can help resolve such issues.
Changes in sound quality may also stem from wax buildup on or inside the hearing aid, or from damage to the device. If you suspect a fault with your hearing aid, reach out to the service provider from whom you obtained it.

How can I get hearing aids?

Currently, digital hearing aids are accessible through the NHS in the United Kingdom, offering good sound quality. Ongoing rehabilitation, servicing, and replacement batteries are provided free of charge by the NHS.

Your doctor can refer you to a local audiology service for a hearing test and fitting of a hearing aid. Some audiology services may accept self-referrals.
Alternatively, hearing aids are available for prescription and purchase from private hearing aid dispensers. Opting for private purchase may offer access to the latest technology, including wireless communication accessories and miniaturisation. However, private hearing aids can be costly, with additional expenses for servicing, maintenance, and batteries.

Regardless of the source, it’s crucial to ensure the proper fitting of the hearing aid. This involves verifying the sound delivery to your ear, especially if you have tinnitus. If you feel the settings are not suitable, return to your hearing aid supplier for adjustments. When purchasing a hearing aid privately, ensure it’s covered by insurance for loss or damage, both at home and outside.
