Diplacusis comes from the Greek words “diplous” and “akousis”, which means double hearing. It is the condition that characterised by the perception of a single sound as two separate sounds that may differ in voice,pitch,tone or timing.
Diplacusis also heard as “diplacusis binauralis” or “interaural pitch difference” (IPD). Patients with sensorineural hearing loss (SHL) may experience diplacusis.This is the most common type and it will occur when the people hearing two different sounds from their ears and when the differences become too great to ignore your brain may interrupt them as a two different sounds and differences in the pitch are common and can’t be consider by our brain when it’s low.
Different types of Diplacusis
According to a recent study online published in the U.S. National Library of Medicine National Institutes of Health, the Diplacusis is of four types :-
1. Diplacusis dysharmonica :-
It is the type of disorder in which you perceved the correct pitch normally in one ear while the other ear heard the different pitch. There is the fluctuation in the pitch of the voice which can be recognised by the brain.It’s the most common diplacusis disorder.
2. Diplacusis Binauralis :-
It is the disorder in which the you hear same sound differently in each ear like one ear may hear a sound different pitch and timing with the other it is slightly same to the diplacusis dysharmonica but the difference is its doesn’t hear the sounds from each ears at the same time.
3. Diplacusis Echoica :-
It occures when the timing of tones repeated in a regular interval of time and you sense it like an echo and it is the unusal form of diplacusis disorder.
4. Diplacusis monauralis :-
It occures when the ear hears the same sound as two different sounds it may vary in pitch,time and tone.
What causes Diplacusis?
When people experience some hearing loss in one ear or miscommunication of voice in the ears or uneven hearing in the both the ears which is either in the form of pitch,tone and timing. It may happen sudden due the ear infection,tumor,head trauma or excess amount of earwax inside the earlobe. People may also experienced a ringing and buzzing noise in the affected ear. Which may result in the sensorineural hearing loss, and it may also happen when the ear don’t able to transmit the message to the brain but because of the blocked ear canal but fluids or earwax but that is not always the case.
Diplacusis can be caused by due to some inner ear damage as a result of :-
- ear infection
- Earwax build up
- damage to the inner ear
- a number of other health conditions which impact upon hearing
- Clogged sinuses
- Noise-induced hearing loss (NIHL)
- Trauma to the head
- Certain medications
This hearing loss can be either temporary or permanent in nature.
Test for Diplacusis
According to the experts and professional listening the high variation in volume or pitch my caused the human suffer from the diplacusis. Mostly the musician suffer from the diplacusis because they were used their musical instrument at very high node and constantly vary the volume of the instrument without any interval of time due to this they Suffer from the diplacusis.This is the most commonly reason why musician get high priority to suffer the diplacusis but nevertheless you compare to the other.
In comparison to 1.5% of the general population, widely 5% of musicians admitted experiencing a form of Diplacusis.
Treatment is done only when if it is temporary means, if your diplacusis is caused due to the obstruction. It can be easily resolved by removing the ear wax or ear mud inside the earlobe either you would clean your infected fluid in the earlobe. But if it is permanent then their is no such operation that can remove the diplacusis either you’ve to use the hearing aids or cochlear implants. This will help you to remove the negative symptoms of diplacusis and it is very important to notice the symptoms of diplacusis so that professional can judge the type of diplacusis so that they can apply the correct treatment for the diplacusis. So if you notice any symptoms of hearing loss my contact with your family consultant so that they can applied the treatment without without facing any anomaly.
