Is the occlusion effect primarily a high frequency phenomenon?

The occlusion effect is not primarily a high frequency phenomenon, which supports the answer that it is false. The occlusion effect occurs when the ear canal is blocked, typically by an ear plug or hearing aid, leading to an increase in sound pressure level in the ear canal. It can affect both low and high frequencies, but it is particularly noticeable for lower frequencies. This is due to the way sound waves transmit through the ear and how the ear canal acts as a resonating chamber.

In contrast, the perception of occlusion may vary among individuals based on their hearing loss or ear canal structure, but it is not limited to just particular frequencies. Therefore, the claim that it is primarily a high frequency phenomenon does not hold true, making the correct answer that the statement is false. Understanding this helps hearing aid specialists in managing clients' experiences with hearing aids and addressing any occlusion effects they may encounter.
