Auditory suppression can be described as the experience of audible sound becoming perceived as distant, quiet and muffled. This effect can significantly decrease both the volume of noise and the general level of quality in which it is perceived. That is, it is usually described to make comprehension and to pay attention to music and other sounds difficult.
