Speech reception threshold |
Patient repeats two syllable words presented at lower and low levels until a threshold is reached where the patient is incorrect 1/2 of the time |
|
Word recognition score |
Tests how well patients can hear words and understand words
Useful for assessing potential benefits from hearing aid and for identifying Central auditory nervous system lesion |
|
Speech-in-noise tests |
Tests a patients ability to repeat words in the presence of background noise-can be white noise or speech bubble Real world understanding Useful for patients with difficulty understanding in crowded noisy places, but have "normal" hearing on the audiogram |
|
Auditory Brainstem response |
When a sound is heard, various locations in the brain stem generate measurable electrical potentials These waves have presumable latencies If the waves are late, can be indicator of lesions location |
|
When do you need an ABR? |
Used in infant hearing testing, tumors, de-myelinating diseases, auditory neuropathy. Used for possible injuries/abnormalities of the auditory nerve or brain stem |
|
Oto acoustic emissions |
OAE-tests for hearing |
|
Excessive cerumen |
Otoscopy reveals it First tympanogram with low ear canal volume Conductive hearing loss |
|
Clues to Otitis media with effusion |
Patient case history: history of OM Otoscopy reveals fluids behind the TM or bulging TM Fiat tympanogram with normal ear canal volume Conductive hearing loss |
|
Otosclerosis |
Typically unilateral Causes conductive hearing loss with a unique configuration |
|
Nose induced hearing loss |
Patient case history Occupational/recreational nose exposure Normal otoscopy and tympanogram |
