    Here's how to read an audiogram and a doctor's explanation of the most common results including sloping hearing loss, notched hearing loss, cookie-bite hearing loss and reverse-sloping hearing loss.

  3. 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.

  4. Sensorineural hearing loss - Wikipedia

    en.wikipedia.org/wiki/Sensorineural_hearing_loss

    Hearing loss completely recovers in around 35–39% of patients with SSNHL, usually within one to two weeks from onset. [34] Steroid treatment within seven days, a lower initial severity of hearing loss, the absence of vertigo, younger patient age, and a history of cardiovascular disease are all associated with complete hearing recovery. [35]

  5. Audiogram - Wikipedia

    en.wikipedia.org/wiki/Audiogram

    Audiograms are unable to measure hidden hearing loss, [15] [16] which is the inability to distinguish between sounds in loud environments such as restaurants. Hidden hearing loss is caused by synaptopathy in the cochlea, [17] as opposed to sensorineural hearing loss caused by hair cell dysfunction. Audiograms are designed to "estimate the ...

  6. Minimum audibility curve - Wikipedia

    en.wikipedia.org/wiki/Minimum_audibility_curve

    This is not the best threshold found for all subjects, under ideal test conditions, which is represented by around 0 phon or the threshold of hearing on the equal-loudness contours, but is standardised in an ANSI standard to a level somewhat higher at 1 kHz . There are several definitions of the minimal audibility curve, defined in different ...

  7. Tone decay test - Wikipedia

    en.wikipedia.org/wiki/Tone_decay_test

    A tone at the frequency of 4000 Hz is presented for 60 seconds at an intensity of 5 decibels above the patient's absolute threshold of hearing. If the patient stops hearing the tone before 60 seconds, the intensity level is increased by another 5 decibels with the procedure repeated until the tone can be heard for the full 60 seconds or until no decibel level can be found where the tone can be ...

  8. Diagnosis of hearing loss - Wikipedia

    en.wikipedia.org/wiki/Diagnosis_of_hearing_loss

    Given that hearing loss can vary by frequency and that audiograms are plotted with a logarithmic scale, the idea of a percentage of hearing loss is somewhat arbitrary, but where decibels of loss are converted via a legally recognized formula, it is possible to calculate a standardized "percentage of hearing loss", which is suitable for legal ...

  9. Audiometry - Wikipedia

    en.wikipedia.org/wiki/Audiometry

    Pure tone audiometry is a standardized hearing test in which air conduction hearing thresholds in decibels (db) for a set of fixed frequencies between 250 Hz and 8,000 Hz are plotted on an audiogram for each ear independently. A separate set of measurements is made for bone conduction.
