Just as eyeglass frames with prescription lenses must be properly fitted to the wearer’s face, a hearing instrument’s earmold must fit perfectly in the listener’s ear. To get the fit that will literally place the sound of the hearing instrument in the ear, an audiologist will make a cast (known as an “impression”) of the ear. After the working earmold is made from this impression, it will be adjusted to prevent any “feedback” problems that might arise from a loose fit that allows unwanted sounds to leak past the earmold and into the ear. Additional modifications may also be made to address any “occlusion effect” (muffled sounds) or any perception that the user’s own voice is too loud.
P.S. An earmold can be canal size (tiny), half-shell size (medium), or even “full shell” size (large), depending on the wearer’s type and degree of hearing loss and anatomy.
The future of the hearing industry is bright. There is amazing technology already available in modern hearing instruments, and there is no limits to the technological advances that will be available in a few short years.
