Auditory suppression can be described as the experience of audible noises becoming perceived as more distant, quiet and muffled than they actually are. This effect can significantly decrease both the volume of a noise and the general level of quality in which it is perceived. It is usually described as making it difficult to comprehend or fully pay attention to music and other sounds.
Auditory suppression is often accompanied by other coinciding effects such as auditory distortion and auditory hallucinations. It is most commonly induced under the influence of moderate dosages of dissociative compounds, such as ketamine, PCP, and DXM. However, it can also occur less commonly under the influence of GABAergic depressants and antipsychotics such as alcohol and quetiapine.
