Therapy in helping the patient understand the cause of the symptom and tinnitus retraining may provide some relief. In at least some cases, amplification makes no difference and there is no treatment other than waiting for natural resolution. Some individuals may find the provided amplification also increases the audibility of their pitch discrepancy. If onset is linked to an underlying medical cause, i.e. sudden sensorineural hearing loss, appropriate medical treatment is recommended. Etymology
Diplacusis is from the Greek words "diplous" (double) and "akousis" (hearing). See also

The letter h may represent /h/ as in the name of the Székely town Hargita; intervocalically it represents /ɦ/ as in tehén; it represents /x/ in the word doh; it represents /ç/ in ihlet; and it is silent in cseh. As part of a digraph, it represents, in archaic spelling, /t͡ʃ/ with the letter c as in the name Széchenyi; it represents, again, with the letter c, /x/ in pech (which is pronounced [pɛxː]); in certain environments it breaks palatalization of a consonant, as in the name Beöthy which is pronounced [bøːti] (without the intervening h, the name Beöty could be pronounced [bøːc]); and finally, it acts as a silent component of a digraph, as in the name Vargha, pronounced [vɒrgɒ]. In Ukrainian and Belarusian, when written in the Latin alphabet, ⟨h⟩ is also commonly used for /ɦ/, which is otherwise written with the Cyrillic letter ⟨г⟩. In Irish, ⟨h⟩ is not considered an independent letter, except for a very few non-native words, however ⟨h⟩ placed after a consonant is known as a "séimhiú" and indicates lenition of that consonant; ⟨h⟩ began to replace the original form of a séimhiú, a dot placed above the consonant, after the introduction of typewriters. In most dialects of Polish, both ⟨h⟩ and the digraph ⟨ch⟩ always represent /x/. In Basque, during the 20th century it was not used in the orthography of the Basque dialects in Spain but it marked an aspiration in the North-Eastern dialects.
