| Term | Definition |
|---|---|
| Tinnitus | auditory perception not produced by an external stimulus |
| Habituation | Less and less electrical responses are evoked due repeated exposure to a stimulus |
| Consent | Everyone has a right to know what procedures will take place; the patient gives a verbal or written agreement |
| Assumed Consent | Informal consent; assumed for non invasive procedures, including case history |
| Assent | Agreement to take part in a procedure is given but not required by law |
| Protected Health Information (PHI) | Information that would be found on a patient's medical chart |
| Immittance | Total amount of resistance and ease with which energy flows through the middle ear system |
| Impedance | Amount of resistance to flow energy has through the middle ear system |
| Admittance | Amount of ease with which energy flows through the middle ear system |
| Equivalent Ear Canal Volume (ECV) | mmho under the curve at +200 daPa on a tympanogram |
| Static Admittance | total ear volume-ECV; in mmho |
| Peak Pressure | pressure level where energy has the least amount of impedance in the middle ear |
| Acoustic Reflex | Tensing of the stapedius and tensor-tympani muscles in response to a loud sound |
| Acoustic Reflex Threshold (ART) | Lowest intensity at which immittance changes in the middle ear |
| Otoacoustic Emissions (OAE) | Sounds that are produced by the middle ear |
| Motility | the contracting and lengthening of the outer hair cells in the ear causing OAE |
| Auditory Brainstem Response (ABR) | Electrical activity in the auditory nerve and brainstem |
| Auditory Evoked Potentials (AEP) | Electrical activity we can measure on the surface of the head in response to sound |
| Tympanogram Types | A, Ad, As, B, C |
| Hearing Loss Types | Conductive, Sensorineural, Mixed |
