How frequently should I change my hearing aid domes?

How frequently you need to change your domes comes down to the law of individual differences. As a general rule it is a good idea to change your domes over for fresh ones about once a month or at most every second month. This is to help keep them clean and hygienic and to reduce the risk of wax and debris clogging up the small pores that are beneath the tiny silicone hood and compromising the hearing aid performance.

If you ear canals produce a lot of soft sticky wax you may have to change them over more regularly, even weekly. It is best to replace them rather than trying to clean and reuse them as you won’t always be able to remove all the wax and debris from inside the tiny pores/holes that allow the sound through and if they are blocking up the sound delivery will be affected.

Hearing aid domes come in different shapes and sizes to ensure a snug and comfortable fit, accommodating the unique twists and turns of your unique ear canal.

So the correct acoustic coupling of hearing aid to your ear is essential for optimal performance, comfort and security.
