    The open edge of the bracket indicates the ear tested, with < or [ representing a right bone conduction threshold and > or ] representing a left bone conduction threshold. When colors are used on an audiogram, red indicates the right ear and blue indicates the left ear. [8] [9]

    en.wikipedia.org/wiki/Pure-tone_audiometry

    When the thresholds obtained via air conduction are examined alongside those achieved with bone conduction, the configuration of the hearing loss can be determined. However, with bone conduction (performed by placing a vibrator on the mastoid bone behind the ear), both cochleas are stimulated. IA for bone conduction ranges from 0-20 dB (See ...

    Stapells and Ruben, in 1989, demonstrated bone-conduction tone burst ABRs in infants with conductive hearing loss. [7] Hatton, Janssen and Stapells (2012) present bone-conduction tone burst ABR results in infants with normal bone-conduction thresholds or sensorineural hearing loss. [8] BC ABR methods are described in 2010 review chapter by ...

  5. Bone conduction - Wikipedia

    en.wikipedia.org/wiki/Bone_conduction

    Bone conduction is the conduction of sound to the inner ear primarily through the bones of the skull, allowing the hearer to perceive audio content even if the ear canal is blocked. Bone conduction transmission occurs constantly as sound waves vibrate bone, specifically the bones in the skull, although it is hard for the average individual to ...

  6. Sensorineural hearing loss - Wikipedia

    en.wikipedia.org/wiki/Sensorineural_hearing_loss

    Bone conduction thresholds can differentiate sensorineural hearing loss from conductive hearing loss. Other tests, such as oto-acoustic emissions, acoustic stapedial reflexes, speech audiometry and evoked response audiometry are needed to distinguish sensory, neural and auditory processing hearing impairments.

  7. Conductive hearing loss - Wikipedia

    en.wikipedia.org/wiki/Conductive_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" represents responses in the left ear at each frequency, while the "o" represents responses in right ear at each frequency.

    Thus, a "positive" result indicates the healthy state, in contrast to many other medical tests. Therefore, some prefer to avoid using the terms "positive" or "negative", and simply state if the test was normal or abnormal. For example: "Rinne's test was abnormal in the right ear, with bone conduction greater than air conduction".

  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.
