Auditory and Burn

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.
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
