Pitch, loudness and frequency selectivity in low-frequency
Chronic exposure to noise causes a progressive destruction of inner and outer hair Although diplacusis is usually indicative of cochlear pathology, to our knowledge causes in the central nervous system (“central diplacusis”) have not been mentioned in the available literature. A case of central diplacusis involving a lesion in the posterior thalamus is now reported that resulted in diplacusis binauralis. A neuro-audiological explanation is offered to explain this Diplacusis, also known as diplacusis binauralis, binauralis disharmonica or inter aural pitch difference (IPD) is a type of hearing disorder that is the perception of a single auditory stimulus as sounds of a different pitch in the two ears. Can cause a negative reaction to loud sounds. Diplacusis- Generally occurs when one ear has sustained more damage than the other. Diplacusis Dysharmonica-Present when a tone is perceived normally in one ear but at a different pitch in the other ear.

Diplacusis can be caused by due to some inner ear damage as a result of :- Diplacusis can also occur if you have sensorineural hearing loss in both ears, and there is a big difference between the loss in the right and left ear. Loud sounds (e.g. at concerts) often causes sensorineural hearing damage, but usually affects both ears fairly equally. Diplacusis monauralis occurs when one ear hears the same sound as two different sounds at the same time. Treatment depends on what type of diplacusis is present and localizing the source of the problem leading to the diplacusis. Typically, this would entail an examination of the ear followed by a hearing test.

There are two theories on the cause of diplacusis: place theory and temporal theory. 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. Temporal theory posits that the cause is from looking at the phase locking to tell what the pitch is. Most often, diplacusis starts suddenly. Factors that can cause ear damage are noise-induced hearing loss, head trauma, and specific medications.

The prevalence of all types of diplacusis is still unknown even though the first case of diplacusis was discovered in 1907. More research is needed and there’s a need of studies that include larger study groups. Has anyone here had diplacusis and had it resolve? My dipla is strange because I can never notice it by pure tones. It also occurs in both ears, at specific frequencies too.
