An open fit hearing aid is a behind-the-ear hearing instrument that has a slim tube and a small non-custom earpiece called a “dome.” This type of hearing aid is specifically designed to meet the needs of patients with a high frequency hearing loss.

 

In the past, hearing aid wearers with a high frequency hearing loss often complained regarding the unnatural sound quality of their voice and/or a “plugged up” sensation. Traditional behind the ear or custom in-the-ear hearing aids closed or “plugged” the ear canal preventing unnecessary low frequencies from escaping the ear canal. These low pitches are most often the cause of an unnatural voice quality and/or a “plugged” sensation. Open fit hearing aids have a small earpiece or “dome” that replaces the occluding behind-the-ear earmold or custom in-the-ear hearing aid. This dome has several vents or “holes.” The vents allow unnecessary low pitch sounds to escape resulting in a more natural quality to your voice.
