When you increase the input ratio for medium sounds, what is the effect on gain?

Increasing the input ratio for medium sounds indicates that the device is set to a point where it can handle a higher volume of sound. When this happens, the gain, which is the amplification provided by the hearing aid, is reduced. This is because the hearing aid is designed to prevent distortion or discomfort from loud sounds, so it will adjust the gain downward as the input level, or sound intensity, increases.

This process is integral to how hearing aids manage sound to ensure comfort and clarity for the user, especially in dynamic environments with varying sound levels. Thus, a higher input ratio typically results in decreased gain for medium sounds, helping to maintain audio fidelity and preventing sudden spikes in volume that could be damaging or uncomfortable.
