Study conducted to measure the magnitude and consistency of the occlusion effect for the Post Auricular Canal (PAC) from SeboTek Hearing Instruments, which is a deep-fitting hearing aid that utilizes a linkage from a miniature sound processor to a receiver. One of the main advantages of the PAC’s natural-style fitting is its ability to significantly reduce the occlusion effect, which was measured on 36 adult participants via the determination of intersubject, intrasubject, and different test site variability. Results indicated that the hearing aid significantly reduced the occlusion effect when compared to traditional fittings. A technological evaluation of the PAC and the testing procedures is presented.
