  2. Conductive hearing loss - Wikipedia

    en.wikipedia.org/wiki/Conductive_hearing_loss

    The shape of the plot reveals the degree and nature of hearing loss, distinguishing conductive hearing loss from other kinds of hearing loss. A conductive hearing loss is characterized by a difference of at least 15 decibels between the air conduction threshold and bone conduction threshold at the same frequency. On an audiogram, the "x ...

  3. Weber test - Wikipedia

    en.wikipedia.org/wiki/Weber_test

    The Weber test is administered by holding a vibrating tuning fork on top of the patient's head. The Weber test is a screening test for hearing performed with a tuning fork. [1] [2] It can detect unilateral (one-sided) conductive hearing loss (middle ear hearing loss) and unilateral sensorineural hearing loss (inner ear hearing loss). [3]

  4. Bone-anchored hearing aid - Wikipedia

    en.wikipedia.org/wiki/Bone-anchored_hearing_aid

    A bone-anchored hearing aid (BAHA) [2] is a type of hearing aid based on bone conduction.It is primarily suited for people who have conductive hearing losses, unilateral hearing loss, single-sided deafness and people with mixed hearing losses who cannot otherwise wear 'in the ear' or 'behind the ear' hearing aids.

  5. Sensorineural hearing loss - Wikipedia

    en.wikipedia.org/wiki/Sensorineural_hearing_loss

    PTA can be used to differentiate between conductive hearing loss, sensorineural hearing loss and mixed hearing loss. A hearing loss can be described by its degree i.e. mild, moderate, severe or profound, or by its shape i.e. high frequency or sloping, low frequency or rising, notched, U-shaped or 'cookie-bite', peaked or flat.

  6. Pure-tone audiometry - Wikipedia

    en.wikipedia.org/wiki/Pure-tone_audiometry

    The shape of the audiogram resulting from pure-tone audiometry gives an indication of the type of hearing loss as well as possible causes. Conductive hearing loss due to disorders of the middle ear shows as a flat increase in thresholds across the frequency range. Sensorineural hearing loss will have a contoured shape depending on the cause.

  7. Hearing test - Wikipedia

    en.wikipedia.org/wiki/Hearing_test

    Additionally, the tuning fork is placed on the forehead. The patient is then asked if the sound is localised in the centre of the head or whether it is louder in either ear. If there is conductive hearing loss, it is likely to be louder in the affected ear; if there is sensorineural hearing loss, it will be quieter in the affected ear. This ...

  8. Rinne test - Wikipedia

    en.wikipedia.org/wiki/Rinne_test

    It compares perception of sounds transmitted by air conduction to those transmitted by bone conduction through the mastoid. Thus, one can quickly screen for the presence of conductive hearing loss. [2] A Rinne test should always be accompanied by a Weber test to also detect sensorineural hearing loss and thus confirm the nature of hearing loss.

  9. Cartilage conduction - Wikipedia

    en.wikipedia.org/wiki/Cartilage_conduction

    Air conduction: Sound propagated from a sound source through the air is received by the outer ear, and then transmitted via the ear drum, middle ear, and inner ear. Bone conduction: Sound from a vibrator oscillates the skull bone, and the vibration is transmitted directly to the inner ear without passing through the ear drum and middle ear.
