Auditory acuity suppression
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 which it is perceived in. This can result in music and other sounds becoming extremely difficult to comprehend or pay attention to.
