The fit of your hearing aids may also need to be adjusted periodically. Excessive feedback or whistling may indicate a problem with the fitting, or that a new earmold is needed. Your hearing may also worsen over time, which will require reprogramming your hearing aids. Hearing aid adjustments can typically be done quickly during an office visit.
BTE hearing aid wearers will need to have the tubes on their aids replaced regularly due to stretching, discoloration, hardening, cracking or moisture issues. For hearing aids that require earmolds, such as a BTE hearing aid, there may be a one- or two-week wait to have a new earmold created.
