Auditory and Burn
| Question | Answer |
|---|---|
| Air Conduction | The process by which sound is conducted to the inner ear (cochlea) via the air medium |
| Ambient noise level | The audible alterations in air pressure cause by the present noise of the environment. |
| Amplitude | Air pressure increase at a given point during the occurrence of sound |
| Auditory evoked potential | An acoustically stimulated electrical charge, recorded from specific part of the brain with electroencephalic audiomentry (EEA) |
| Auditory feedback | Return of one;s speech auditory (both via air and bone conduction) |
| Auditory figure-ground discrimination | The ability to shift attention between two sources of auditory stimuli, the primary becoming the figure and the secondary stimulus becoming the ground. |
| Auditory pathways | The major synaptic junction of the V111 cranial nerve located in the medulla and pons area of the brain |
| Bone conduction | The process by which sound is conducted to the nerve of hearing through the cranial bones. |
| Decibel (dB) | A useful measurement for comparing the loudness of two sounds. The decibel in the logarithm of a ratio of two values of power/equal charges in dB represent equal ratio. |
| End Organ | the end organ of hearing is the organ of Corti within the cocklea, where sound stimuli are transduced into electrochemical impulses to be interpreted and acted upon by the brain. |
| Narrow-band masking noise | A masking noise having most of its energy within a narrow, definable band, usually at one-half octave above and one-half octave below a given frequency. |
| Phonetically balanced word list (PB) | Lists of fifty monosyllabic words scientifically chosen so that each list contains samples of speech sounds in the same proportion with which they occur in English speech. |
| Psycholinguistic approach | A field of study that combines behavioral psychology and linguistics. |
| Reverberation time | The time in seconds for sound level in a room to drop 60dB (or to one millionth of its previous intensity). |
| Sound field | A defined region containing sound waves transmitted through loudspeakers rather than earphones. |
| Temporal lobe | The area of the cortex primarily responsible for auditory function. |
| BURN | BEGIN NEW SEDTION |
| Allografts | Skin grafts using cadaver skin which is preserved in a graft bank and then utilized as temporary covering |
| Autografting | Grafting using the individual's own skin |
| Blebs | A primary skin lesion which is irregularly shape and contains fluid at lease one centimeter in diameter |
| Bullae | Circumscribed, fluid-containing, elevated lesions of the skin usually larger than 5 mm in diameter. |
| Chemical Burns | Burns resulting from contact with a corrosive material such as a strong alkali or acid |
| Debriderment | Removal of foreign material or devitalized tissue from an adjacent to a traumatic or infected lesion to expose healthy skin |
| First degree | Burns gave tissue damage limited to the outer layer of the epidermis |
| Second Degree | Burns extend through the epidermis and involve the dermis, but not sufficiently to interfere with rapid regeneration of the epithelium. |
| Third Degree | (full-thickness) burns destroy both epidermis and dermis with destruction of nerve endings |
| Dermis | True skin |
| Electrolyte | A substance that dissociates into ions in solution thus becoming electricity. |
| Enzymatic Debridement | Debridement by means of proteolytic enzyme which selectively digest necrotic (devitalized) tissue with harming adjacent viable tissue |
| Epidermis | The outermost, non-vascular layer of skin which consists of five layers |
| Epithelialization | Healing by growth of epidermis over a denude area |
| Eschar | Necrosed tissue separated from living tissue produced by thermal burn, corrosive application, or gangrene |
| Esposure Method | Burn treatment by exposing wound area to light and maintaining a cool environment, utilized to control bacterial colonization |
