For those with more severe hearing loss, a well-fitting earmold helps to create enough volume without leaking sound out or causing undesired whistling or feedback. Earmold For Flat Hearing Losses
The primary purpose of the earmold is to direct sound from the hearing aid into your ear canal without sound leaking out. Earmolds come in various colors, so you can choose one that best matches ...
An earmold (also spelled; ear mold, ear mould or earmould) is a device worn inserted into the ear for sound conduction or hearing protection. Earmolds are anatomically shaped and can be produced in different sizes for general use or specially cast from particular ear forms. [ 1 ]
Ear cups are usually lined with a sound-absorbing material, such as foam. The cups should be fit so that the center of the ear canal aligns with the ear canal opening. [1] The soft cushions seal around the pinna of the ears. The head band, centered at the top of the head, applies force/pressure to seal the ear cups over the ears. [1]
The case is attached to an earmold or dome tip by a traditional tube, slim tube, or wire. The tube or wire courses from the superior-ventral portion of the pinna to the concha, where the ear mold or dome tip inserts into the external auditory canal.

Real-ear attentuation at threshold (REAT) measurements test how narrowband noises of varying frequency are attenuated with and without the custom mold in place. Testing for low-frequency attenuation can help to verify the earmold fit while testing high-frequency attenuation can verify the properties of the filter used. [6] [21]
