An auditory distortion is the experience of perceived alterations in how audible noises present and structure themselves.     These distortions can manifest in many styles, but commonly take the form of echoes or murmurs which rise in the wake of each sound and are accompanied by fluctuating changes in speed and pitch    . This can intensify up to the point where sounds are consistently followed by continuous reverberation  , often rendering the original sound completely unrecognizable. However, it often quickly resets to base level and starts over if the source of noise is stopped or changed. The experience of this effect can be broken down into three distinct levels of intensity. These are described and documented below:
- Mild - At the lowest level of intensity, auditory distortions consist of subtle and spontaneous reverberation, echo effects, and changes in pitch of noises within the external environment. They are fleeting, low in intensity, and easy to ignore.
- Distinct - At this level, auditory distortions consist of distinctly noticeable, spontaneous echo effects and changes in pitch attributed to noises within the external environment. They are long and drawn out and loud enough to become difficult to ignore.
- All-encompassing - At the highest level, auditory distortions become constant and impossible to ignore. The complexity of the resulting alterations quickly renders the original sound as unintelligible.
