Puretone Audiometry (PTA)

Pure Tone Audiometry is a hearing test used to check how well a person can hear different sounds at different pitches and volumes. It’s like a simple way to measure your hearing ability.

Here’s how it is performed

  • The person being tested wears headphones that play sounds, usually beeps, at different volumes and pitches (like high or low sounds).
  • The test involves a series of tones that get quieter and quieter, and the person has to press a button or raise their hand every time they hear a sound.
  • The results show the quietest sounds that a person can hear at different frequencies, which helps the doctor or audiologist understand if there’s any hearing loss and how severe it might be.

It’s a standard test used to check hearing, especially for conditions like hearing loss, and it’s often done for children or anyone who might need a hearing evaluation.

Our Specialists are highly qualified and trained to let you know on the following information;

After this test performed You get to know about

  • Your hearing status overall
  • If any abnormal findings then
  • Type of hearing deviance
  • Amount of hearing deviance
  • Need for further assessment
  • Necessary Information on Type of treatment
  • Posttest counselling and education

Impedance Testing (Tympanometry):

This is a type of hearing test that measures how well your middle ear is working. It’s often used to check for issues like ear infections, fluid in the ear, or problems with the eardrum or the bones in the middle ear.

    The Test Procedure:
  • A small, soft probe is placed in the ear canal. The probe sends a gentle puff of air into the ear, which causes the eardrum to move slightly.
  • The test then measures how the eardrum reacts to the air pressure, which helps doctors understand how well the middle ear is working.
    • What It Measures:
  • Tympanic membrane (eardrum) mobility: If the eardrum is moving properly, it indicates that sound is traveling efficiently through the ear.
  • Middle ear pressure: This can show if there’s fluid or other blockages in the ear.
  • Acoustic reflex: This is the ear’s natural reaction to loud sounds, helping to assess how well the ear’s muscles and nerves are functioning.
    • Why It’s Important
  • Ear infections (which can cause fluid buildup)
  • Eustachian tube dysfunction (which can affect ear pressure).
  • Hearing loss that might be caused by issues in the middle ear, not the inner ear.
    • The Test is Quick and Non-Invasive:
  • It’s a painless test, takes just a few minutes, and doesn’t require any special preparation.
  • Children who have recurrent ear infections
  • Adults who have unexplained hearing issues
  • Routine screenings in clinics or schools

By performing this test, our specialists get a clearer picture of the health of the middle ear and whether there might be any need for further treatment or tests.

Otoacoustic Emissions (OAE) Testing

This is a quick, painless test used to measure the sounds your inner ear (cochlea) makes in response to sounds. It’s commonly used to screen for hearing loss, especially in newborns and young children, but can also be used for adults in certain situations.

    The Test Procedure:
  • A small probe is placed in the ear canal, which includes a tiny speaker and microphone.
  • The speaker plays a series of soft sounds (like clicks or tones) into the ear.
  • The microphone picks up any sound that the ear generates in response.
  • The test lasts just a few minutes and is completely painless. It doesn’t require you to do anything except stay still.
    • What It Measures:
  • OAE Response: If the cochlea is healthy, you’ll get a normal response, meaning the ear produces the otoacoustic emissions.
  • Absent or Abnormal Response: If there’s a problem with the ear or hearing loss, the response may be weak or absent. This doesn’t necessarily mean a person is completely deaf, but it indicates there may be some hearing loss or other ear issues.
    • Why is OAE Testing Important?
  • For Newborns and Infants: OAE testing is often used in newborn hearing screenings because it can help detect hearing loss early. Early detection allows for prompt treatment, such as hearing aids or other interventions, which can greatly improve speech and language development.
  • For Adults and Children: It can also be used to detect damage to the cochlea (inner ear) caused by things like loud noise exposure, certain medications, or aging. It’s a helpful tool in diagnosing hearing loss early.
  • Hearing loss that might be caused by issues in the middle ear, not the inner ear.
    • What Does the Test Help Diagnose?
  • Hearing Loss: If the cochlea or inner ear is not functioning properly, you may not produce normal otoacoustic emissions, suggesting hearing loss.
  • Middle Ear Problems: Sometimes, issues with the middle ear (like fluid or a blocked ear) can interfere with OAE results, so the test can sometimes help indicate the need for further evaluation.
    • Benefits of OAE Testing:
  • Fast and Non-Invasive: It’s easy and quick, and there’s no need for any discomfort or preparation.
  • Reliable: It gives clear results about the function of the cochlea and can be an excellent tool for detecting early hearing issues.
  • For All Ages: It’s used for newborns (often as part of routine hearing screenings), as well as for adults or older children when hearing problems are suspected.
    • What Happens After the Test?
  • If your results are normal, your hearing is likely functioning well in the inner ear (cochlea).
  • If the test shows abnormal results, it doesn’t automatically mean you have hearing loss—it could mean there's a temporary issue like fluid or an ear infection. Your doctor might recommend further tests to determine the cause.

Brain Stem Evoked Response Audiometry (BERA)/ Auditory Brainstem Responses (ABR):

The Brain Stem Evoked Response Audiometry (BERA) is an objective test that gives us the approximate average hearing threshold level of the subject. It is a very reliable yet sometimes time-consuming test to objectively evaluate the hearing thresholds of an adult or child. This test is used to check the structural and functional integrity of the auditory pathway from the inner ear to the midbrain. Many neurotological disorders that present with vertigo or deafness have defects in this portion of the auditory pathway in the brain. This is hence one of the basic investigations in patients suffering from vertigo, imbalance, hearing deficit and tinnitus. The test is also used to determine the degree of hearing loss objectivity in pediatric patients as well as in difficult to test patients who do not respond reliably to the subjective tests of hearing like the pure tone audiometry and allied tests.

    Our specialists are effective to perform this assessment under the following conditions:
  • When children present with multiple difficulties
  • To provide excellent hygienic conditions.
  • To precisely locate neurological abnormality.

Tinnitus assessment & management:

Tinnitus is the perception of sound in the ears or head without an external source. It is often described as ringing, buzzing, or hissing noises, and it can range in severity. Assessing tinnitus requires a comprehensive approach to understand its causes, severity, and impact on the individual. Here’s an overview of our specialists’ approach towards tinnitus assessment procedures.

    Detailed patient history: Including onset, description, and impact on daily life
  • Physical examination: To rule out ear or neurological issues.
  • Audiological assessment: Including hearing tests and other measures to assess ear function.
    • Tinnitus Matching and Masking
  • Tinnitus Pitch Matching: A test in which the patient is asked to match the perceived pitch of their tinnitus to an external sound. This helps to characterize the frequency of the tinnitus and can guide management strategies.
  • Tinnitus Loudness Matching: The patient is asked to match the perceived loudness of the tinnitus to an external sound at different levels.
  • Tinnitus Masking: This test involves playing white noise or other masking sounds to determine whether the tinnitus can be masked or alleviated by external sounds, which is an important aspect of treatment planning.
    • Questionnaires: To assess the severity and impact of tinnitus on quality of life.
  • Imaging: If needed to investigate underlying structural causes.
  • Psychological assessment: To evaluate the emotional and mental health impact.
  • Laboratory tests: For systemic or underlying medical conditions.

    • Tinnitus assessment is a multifaceted process that requires careful consideration of both medical and psychological factors. Accurate diagnosis is crucial for effective management and improving the patient’s quality of life.
