Is it true that the occlusion effect is minimized with deep-fitting hearing instruments?

• A. True
• B. False
• C. Depends on the model of hearing aid
• D. Only in certain conditions

Answer: (A)

The statement regarding the occlusion effect being minimized with deep-fitting hearing instruments is indeed accurate. Deep-fitting hearing aids are designed to sit further within the ear canal, which can significantly reduce the occlusion effect, a phenomenon where the amplification of low-frequency sounds (like the wearer’s own voice or chewing) is perceived as being overly amplified or distorted. When the hearing aid is properly fitted deep into the ear canal, it helps to create a seal that reduces the likelihood of sound waves reflecting back into the canal, therefore lessening any sensation of fullness or pressure that can be caused by the occlusion effect. In contrast, more shallow fittings do not provide the same level of isolation from ambient noise and can lead to a more pronounced occlusion effect. So, it is primarily the design and fitting depth of the hearing aids that influence this auditory phenomenon.
