Diplacusis : Facing the Bizarre Reality of Double Hearing

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 :-

  1. ear infection
  2. Earwax build up
  3. damage to the inner ear
  4. a number of other health conditions which impact upon hearing
  5. Clogged sinuses
  6. Noise-induced hearing loss (NIHL)
  7. Tumor
  8. Trauma to the head
  9. 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.

Stuttering and Stammering: Symptoms, diagnosis, and Causes

What is Stuttering and Stammering?

It is Speech Disorder in which the flow of speech is disrupted (break), Stuttering is also known as stammering. Stuttering and Stammering both are different words but describe the same thing. Speech is disrupted means involuntary repetitions and delay of sounds, syllables, words or phrases, silent pauses or blocks, who stutters they are unable to produce clear sounds. Who stutter they have abnormal hesitation or pausing before speech, Usually they face problem to speak vowels and semivowels words. Repetition is the primary problem. This connect the fears of sound to specific vowels and consonants, anxiety, Shame, stress, self-imposed isolation.

Stuttering is not a physical problem to production of sounds or putting thoughts in words. Nervousness and stress do not causes of stuttering but we can say trigger stuttering in people who have the speech disorder. The disorder is also variable, means that in certain situation, like talking on the telephone or in a group and during a presentation to a large crowd.

This speech disorder affects less than 1% of all adults, Mostly this problem occurs in children when they learning to speak. For this problem some kind of professional help available such as speech therapy.


A person who stutters they repeats words or phrases,they have problems to starts some words (some may vowels and semivowels, consonants , they may blink rapidly.

The main symptom is they want to say some words when their mouths are correct position to say the words, but virtually no sound comes out.

Here some common signs and symptoms :-

  1. Repeating a sounds, words and phrases.
  2. Hesitation
  3. Problems starting a words and sounds
  4. Rapid blinking
  5. Trembling lips
  6. Trembling jaw
  7. The face and upper body tightens


Now I discussed some main characteristics of Stuttering and Stammering :-

A.   Primary behaviors

 Repeating sounds, words or phrases, silent blocks and delay of sound. These differ from the normal speakers, for produce the words and phrases they effort and strain. For example :- “on on on a chair”, “ c c cold”, mmmm.

B.   Variability

 Like public speaking and speaking on telephone, they are greatly feared who suffer stuttering problem.


No single cause of stuttering and stammering, experts are not completely sure what is main cause but some genetic problem and it always arises from repetition of sounds or words, sometimes it include physical trauma. When the signals are not working between nerves and muscles are not working properly, and adults also affect after a brain injury. Here some causes of stuttering :

  1. Stroke
  2. Head trauma
  3. Block of blood flow to the brain
  4. Tumors


Stuttering is diagnosis by the DSM-5 diagnostic codes through clinical psychologists with expertise.

Psychological factors:- It make stuttering worses for people who already stutter. In other words anxiety, nervousness, and stress do not causes of stuttering.


Several treatments are available for individuals to control their speech. First learning strategies minimize stuttering through speed deficiency, breathing regulation, and speech language pathologists teach people who stutter to control and monitor the rate at which they speak.

Some therapy for control the stuttering and stammering :-

  • Fluency shaping therapy
  • Modification therapy
  • Electronic fluency therapy
  • Medications
  • Support
