When you wear hearing aids, there are a number of factors to consider such as the fit, battery accessibility and of course overall comfort. As the seasons change and the temperature rises across the country, it is helpful to know how heat may affect your hearing aids. Your audiologist will be able to guide you in finding the best hearing aid for your needs and answering any questions that may arise.


Heat can adversely affect any type of hearing aid. High temperatures can melt the plastic in a hearing aid. Leaving your hearing aids in an unoccupied vehicle will shorten the battery life, reduce the sound quality and the life of the hearing aids, themself. Instead, store them in a cool and dry location.

Excessive sweat mixed with skin oils, lotion, dust and dirt will clog up the external components. Sweat, like water, has the potential to damage the device’s internal elements causing them to short or cease functioning. Due to the greater likelihood of sweating during the summer, be sure to remove your hearing aids before going to bed to give them time to dry. This will help release any moisture that has accumulated throughout the day. Routinely cleaning your devices will increase their longevity and maintain clarity.

In the Ear (ITE)

ITE hearing aids are situated behind the ear entirely. A narrow, attached tube is positioned directly into the ear canal. Since the tube is so small the ear canal is more open than with other styles. ITE hearing aids are placed entirely inside the outer ear. An audiologist will generally recommend them for those who experience mild to severe hearing loss. The case housing the electronic parts is comprised of plastic, making it susceptible to extreme temperatures and any damage related to exposure to them.

Behind the Ear (BTE)

BTE hearing aids are comprised of a hard plastic case that is fitted behind the ear and connects to a plastic earmold that fits directly inside the outer ear. The case behind the ear holds the electronic components. BTE hearing aids are recommended for people who experience all levels of hearing loss.

Completely in Canal (CIC) 

CIC hearing aids are smaller than other models and almost completely concealed within the ear canal. They are recommended for those experiencing mild to moderately severe hearing loss. Due to their more diminutive size, they are usually endorsed for use by adults.

In the Canal (ITC)

ITC hearing aids are designed to sit in the lower section of the outer ear curvature. Due to their design, they are comfortable and user-friendly. They are larger than CIC hearing aids and can hold a bigger battery, thus leading to longer battery life. Audiologists recommend these for a wide range of hearing loss.

If you are experiencing hearing loss, seek out care from an audiologist who will provide testing to determine your level of hearing loss. Your audiologist will discuss your options and fit you with the best hearing aid to fit your unique needs so you can hear again and live your best life.
