[1][2] The onset is usually spontaneous and can occur following an acoustic trauma, for example an explosive noise, or in the presence of an ear infection.
Diplacusis can be particularly disruptive to individuals working within fields requiring acute audition, such as musicians, sound engineers or performing artists.
[10] Place theory posits that the cause is looking for the edge of the wave for the pitch and could explain diplacusis as a small differences between the two cochleas.
[citation needed] The pitch may be difficult to match because the SNHL ear hears the sound "fuzzy".
Treatment of diplacusis includes a full medical and audiological examination that may explain the nature of the problem.
