How much wind noise is generally decreased in a CIC fitting?

In a completely-in-canal (CIC) hearing aid fitting, users typically experience a reduction in wind noise due to the design of the hearing aid. The CIC style is custom-molded to fit deep within the ear canal, which not only benefits the device's aesthetics but also enhances its wind noise reduction capabilities.

The answer indicating a decrease of 26 dB in wind noise is grounded in the acoustic properties of the device. When the hearing aid fits snugly in the ear canal, it creates a physical barrier against wind turbulence, significantly diminishing the amount of wind sound that would otherwise be captured and amplified. This reduction of wind noise can greatly enhance the user experience, particularly in outdoor settings or windy conditions, allowing for clearer hearing without the distraction of unwanted noise.

The other choices reflect levels of noise reduction that may not be commonly observed for CIC fittings. This is likely due to variability in hearing aid construction and design, as well as different environmental factors affecting wind noise. In practical applications, the 26 dB decrease is most commonly emphasized as a reliable expectation for CIC fittings.
