| audiometry, pure-tone | Measurement of hearing based on the use of pure tones of various frequencies and intensities as auditory stimuli. (12 Dec 1998) |
|---|---|
| pure tone audiogram | A chart of the threshold for hearing acuity at various frequencies usually expressed in decibels above normal threshold and usually covering frequencies from 128 to 8000 Hz. (05 Mar 2000) |
| pure-tone audiometer | An electroacoustical generator which produces pure tones of selected frequencies and calibrated output. (05 Mar 2000) |
| pure-tone audiometry | Audiometry utilizing tones of various frequencies and intensities as auditory stimuli to measure hearing, including comparisons of results from testing air conduction and bone conduction. (05 Mar 2000) |
| masking | 1. The use of noise of any kind to interfere with the audibility of another sound. For any given intensity, low pitched tones have a greater masking effect than those of a high pitch. 2. In audiology, the use of a noise applied to one ear while testing the hearing acuity of the other ear. 3. The hiding of smaller rhythms in the brain wave record by larger and slower ones whose wave form they distort. 4. In dentistry, an opaque covering used to camouflage the metal parts of a prosthesis. 5. In radiography, superimposition of an altered positive image on the original negative to produce an enhanced copy photographically. See: subtraction. (05 Mar 2000) |
| perceptual masking | The interference of one perceptual stimulus with another causing a decrease or lessening in perceptual effectiveness. (12 Dec 1998) |
| unsharp masking | In radiography, superimposing a blurred negative of a radiograph to cancel large density differences, leaving fine detail more visible. (05 Mar 2000) |
| affective tone | The mental state (pleasure, repugnance, etc.) that accompanies every act or thought. Synonym: affective tone, emotional tone, affectivity. Fundamental tone, the component of lowest frequency in a complex tone. (05 Mar 2000) |
| tone | 1. The normal degree of vigour and tension, in muscle, the resistance to passive elongation or stretch, tonus. 2. A particular quality of sound or of voice. 3. To make permanent or to change, the colour of silver stain by chemical treatment, usually with a heavy metal. Origin: Gr. Tonos, L. Tonus (18 Nov 1997) |
| tone colour | The distinguishing quality of a sound, by which one may determine its source. Synonym: tone colour. Origin: Fr. (05 Mar 2000) |
| tone decay test | The sounding of a continuous tone at threshold for 1 min; if the intensity must be increased by more than 5 dB for continued perception, it may be a sign of retrocochlear damage. (05 Mar 2000) |
| Traube's double tone | A double sound heard on auscultation over the femoral vessels in cases of aortic and tricuspid insufficiency. (05 Mar 2000) |
| feeling tone | The mental state (pleasure, repugnance, etc.) that accompanies every act or thought. Synonym: affective tone, emotional tone, affectivity. Fundamental tone, the component of lowest frequency in a complex tone. (05 Mar 2000) |
| low tone deafness | Inability to hear low notes or frequencies. (05 Mar 2000) |
| red-cell aplasia, pure | Suppression of erythropoiesis with little or no abnormality of leukocyte or platelet production. (12 Dec 1998) |
