People who are buying the hearing aid will come across the term “Hearing Aid Domes”. It is a soft, little bell-shaped piece of plastic that is placed at the tip of the hearing aids, especially the receiver in the canal hearing aids. The dome is attached to the tubing on the hearing aid, and it fits snugly inside your ear.
A hearing aid dome will help to direct the boosted sound signal coming from the hearing device to the ear canal. This will allow greater sound and frequency detection with fewer unwanted external sounds. However, hearing aid domes do not come in universal sizes. Hence, each individual must work with the Audiologist to find the right type of dome that fits them perfectly
Once the correct size dome is chosen; the next important step is to select the right size. Domes are of different sizes and diameters and an Audiologist must ensure that the fit is adequate for each client. The ear dome should be just big enough such that it forms a snug fit in the ear canal but not so big that it becomes too uncomfortable or puts pressure on the ear. If the selected dome is large, one can experience pain and the sounds heard will be too deep. If the dome is too small, it may fall out of place very easily and will not provide adequate sound quality.
Ear domes have to be changed once every two months ideally or when the Audiologist recommends one to do so. Replacing them consistently will ensure the best functioning and sound quality from the hearing aids.
