What is Diplacusis?

  1. Diplacusis

Considered uncommon, a hearing disorder known as diplacusis can exert a significant impact upon stricken individuals. Those with this condition often hear the same sounds but different ways. Beltone Audiology, a hearing care company dedicated to helping those with hearing impairments live healthy and productive lives, invites our clients interested parties to learn pertinent information surrounding the audio malady.

Causes of Diplacusis

In many instances, the illness’s onset is immediate. The disease can be precipitated by a variety of different factors. Some of these factors can be the result of acute causes such as an ear infection, ingestion of certain medications or head trauma caused by a fall or accident. However, the ailment might also be elicited by chronic exposure to loud noises like booming music, a gradual obstruction in the ear canal brought on by earwax or more serious issues like tumors or underlying medical conditions like autoimmune disorders.


The physical manifestations individuals may experience will depend upon the specific type of diplacusis. Typically, diplacusis occurs in both ears which is medically classified as diplacusis binauralis. Though not as common, it can occur in one ear. In such cases, the correct scientific classification is diplacusis monoauralis.

Those diagnosed with diplacusis often experience issues with the specific pitches and speed with which certain sounds are heard. For example, those with the binauralis manifestation usually hear one sound in one ear and the same sound but in a different pitch in the other ear. Hearing different pitches is known as diplacusis dysharmonica.

In other cases, impacted persons might hear the same sound but at different speeds. For example, one ear will hear the original sound and the other ear will hear the same sound but following a short duration. This form of the ailment is categorized as diplacusis echoica.

In addition to the bizarre hearing patterns those with diplacusis typically experience, individuals might also have other symptoms such as hearing loss and tinnitus (ringing in the ears).

Potential Treatment Options

There is no one specific treatment for diplacusis. The therapeutic protocol employed by a physician or hearing specialist will depend upon the exact underlying cause. For example, if the ailment can be traced back to an obstruction, infection or usage of specific medication, eliminating the pathogen in question, alleviating the blockage or cessation of the offending drug might provide swift relief. That said, the problem could be longer lasting or possibly permanent if the underlying cause is was some type of traumatic or chronic ear damage.
