The exact causes of<unk>  and the associated pathways and mechanisms are still being studied. Some of the popular theories include: Introduction of artifacts in audio material Musicality, especially on the radio, contains musical aspects (timbre, emotional impact, melody), and artifacts that arise from non-musical aspects (soundstaging, dynamic range compression sonic balance). The introduction of these sonic artifacts affects the balance between these musical and non-musical aspects. When the volume of music is higher, these artifacts become more apparent, and because they are uncomfortable for the ear, cause<unk> s to "tune out" and lose focus or become tired. These<unk> s may then unconsciously avoid that type of music, or the radio station they may have heard it on. Sensory overload When exposed to a multitude of sounds from several different sources, sensory overload may occur. This overstimulation can result in general<unk>  and loss of sensation in the ear. The associated mechanisms are explained in further detail down below. Sensory overload usually occurs with environmental stimuli and not noise induced by listening to music.
