What is the primary purpose of the peak clipping technique?

The primary purpose of the peak clipping technique is to prevent distortion from sharp sounds. This technique is used in hearing aids to limit the sound levels that are amplified beyond a certain threshold. When sounds exceed this threshold, peak clipping reduces their intensity rather than allowing them to reach a level that could cause distortion. This is particularly important in maintaining sound quality and ensuring that loud impulsive sounds, which can be uncomfortable or harmful to the user, are controlled. The clipping process helps to ensure that the amplified sound remains within a manageable range, thereby enhancing the listening experience without introducing distortion that could occur if the sound was simply amplified without moderation. By focusing on the peaks of sounds, this technique allows for a clearer and more pleasant auditory experience for individuals who are using hearing aids.
