AUDIOLOGY AND HEARING AIDS PLEASE CONTACT KUNNAMPALLIL GEJO 09995270260

Department Of Audiology



Our centre has air conditioned two individual newly built acoustically designed sound treated room. with two room setup. equipped with high quality audiometers and impedance meters with ANSI standards calibration.
We have other tests like Auditory brain stem Response (BERA) Auditory steady state Response (ASSR), DPOAE,TEOAE, in newly built acoustically designed sound treated room.
  • 1. Puretone Audiometry (PTA)

    -Helps to rule out type and degree of hearing loss.
    -In PTA a wide range of frequencies (250 Hz to 8 KHz) are being tested.
    -Special Tests Like(SISI, TDT, ABLB, STENGER) helps to find out the site of lesion.
    -Speech – Audiometry (SRT, SDT, SAL,MCL,UCL) helps to find out the Speech discrimination level.
  • 2. Impedence audiometry

    -Helps to rule out middle ear status and function
    -Provides information regarding middle ear pressure, compliance and ear canal volume
  • 3. Auditory Brain Stem Respomse (BERA)

    Electro physiologic measures play a critical role in the assessment of hearing in infants and young children. ABR are generated by the cochlea and auditory path way neurons. ABR represents the neural activity of 8th nerve centrals and tracts with in brain stem. ABR is recorded by placing electrodes on scalp and stimulating ear with brief auditory signals.

    -It helps to provide information about degree of hearing loss in children difficult to test patients.
    -To rule out site of lesion.
  • 4. Auditory steady state Response (ASSR)

    -Helps to provide information about degree of hearing loss in children / difficult to test patients.
    -Frequency specific threshold estimation is possible (250 Hz – 8KHz)
    -Helps in providing APT amplification devices to children.
  • 5. OTOACOUSTIC EMISSION (OAE)

    Otoacoustic emissions are sound produced either spontaneously or evoked by the cochlea specifically the outer hair cells, and measured in the outer ear canal.
    There are three types of otoacoustic emission.

    1. Spontaneous (SOAES)

    These are recorded without any presentation of a stimulus and are not typically of any clinical use. They occur in about 35 to 50 % of normal hearing ear’s.

    2. Transient evoked (TEOAEs)

    These are evoked response from stimulating the cochlea with a transient signal such as a click or tone burst acoustic signal.
    TEOAEs are a wide frequency response in the 500 to 5,000Hz range.
    They typically do not occur in hearing loss of about 30 dB or greater.

    3. Distortion product (DPOAEs)

    These are evoked response OAEs from stimulating the cochlea with two simultaneously presented pure tones of different frequency. This type of OAE can be recorded in individuals with greater frequencies with more frequency specificity. DPOAEs are obtainable in the frequency range of 500 to 8000KHz.
    The presence of otoacoustic emissions suggests normal outer hair cell function, Which in turn correlates to normal hearing.
