Audiology Terms as a review for exam
Term | Definition | Description |
---|---|---|
Audiometry | (blank) | (blank) |
Audiometer | device for presenting sounds to the patient at precisely controlled intensity | (blank) |
Pure Tone Audiogram | patient's thresholds of auditory sensitivity for pure tone stimuli | (blank) |
Conductive Hearing Loss | caused by diseases or obstructions in the outer or middle ear (the conduction pathways for sound to reach the inner ear). | ((The air-bone gap (ABG) should be at least 10 db.))Hearing by AC is poorer than hearing by BC and BC is within normal limits |
Sensorineural Hearing Loss | hearing losses result from damage to the delicate sensory hair cells of the inner ear or the nerves which supply it. | ((No ABG)) Hearing by AC=BC and both are impaired to the same degree |
Mixed Hearing Loss | hearing loss refers to a combination of conductive and sensorineural loss and means that a problem occurs in both the outer or middle and the inner ear. | ((ABG))Hearing by AC is poorer than hearing by BC and both are impaired |
