|---|---|---|---|
| 설명 | 특정한 자극을 귀나 청각에 관계하는 곳에 가해서 청력을 측정하는 방법. 여러 가지가 있지만 대표적인 것은 다음과 같다. ①순음청력검사(pure tone audiometry): 삐-소리가 나는 순음을 크기나 강도를 달리하여 들려주고 들을 수 있는지 여부를 이용하여 청력을 검사하는 방법. ②어음청취검사(speech audiometry): 단음절어나 2음절어를 크기나 강도를 달리하여 들려주고 이것을 듣는지 못듣는지를 알아내어 청력을 검사하는 방법. |

| acoustic impedance | The resistance that a material offers to the passage of a sound wave (colloquial); a property of a medium computed as the product of density and sound propagation speed (characteristic acoustic impedance). Discontinuities in acoustic impedance are responsible for the echoes on which ultrasound imaging is based. Unit: the rayl. (05 Mar 2000) |

| acoustic impedance tests | Objective tests of middle ear function based on the difficulty (impedance) or ease (admittance) of sound flow through the middle ear. These include static impedance and dynamic impedance (i.e., tympanometry and impedance tests in conjunction with intra-aural muscle reflex elicitation). This term is used also for various components of impedance and admittance (e.g., compliance, conductance, reactance, resistance, susceptance). (12 Dec 1998) |
| cardiography, impedance | A type of impedance plethysmography in which bioelectrical impedance is measured between electrodes positioned around the neck and around the lower thorax. It is used principally to calculate stroke volume and cardiac volume, but it is also related to myocardial contractility, thoracic fluid content, and circulation to the extremities. (12 Dec 1998) |
| plethysmography, impedance | Recording changes in electrical impedance between electrodes placed on opposite sides of a part of the body, as a measure of volume changes in the path of the current. (12 Dec 1998) |
| impedance | 1. Total opposition to flow. When flow is steady, impedance is simply the resistance, e.g., the driving pressure per unit flow; when flow is changing, impedance also includes the factors that oppose changes in flow. Thus, deviations of impedance, from simple ohmic resistance because of the effects of capacitance and inductance, become more important in alternating current as the frequency of oscillations increases. In fluid analogies (e.g., pulsatile flow of blood, to-and-fro flow of respiratory gas), impedance depends not only on viscous resistance but also upon compressibility, compliance, inertance, and the frequency of imposed oscillations. 2. Resistance of an acoustic system to being set in motion. (05 Mar 2000) |
| impedance angle | A term expressing the ratio of electric resistance to electric capacitance (ohms to microfarads) in the tissues of the body or any other substance. (05 Mar 2000) |
| impedance method | A method for localizing brain structures by measuring impedance of electric current. (05 Mar 2000) |
| electric impedance | The opposition to the flow of an alternating current, which is the vector sum of ohmic resistance plus additional resistance, if any, due to induction, to capacity, or to both. (12 Dec 1998) |
| audiometry | The measurement of hearing. (12 Dec 1998) |
| audiometry, evoked response | A form of electrophysiologic audiometry in which an analog computer is included in the circuit to average out ongoing or spontaneous brain wave activity. A characteristic pattern of response to a sound stimulus may then become evident. Evoked response audiometry is known also as electric response audiometry. (12 Dec 1998) |
| audiometry, pure-tone | Measurement of hearing based on the use of pure tones of various frequencies and intensities as auditory stimuli. (12 Dec 1998) |
| audiometry, speech | Measurement of the ability to hear speech under various conditions of intensity and noise interference using sound-field as well as earphones and bone oscillators. (12 Dec 1998) |
| auditory brainstem response audiometry | An electrophysiologic measure of auditory function utilizing responses produced by the auditory nerve and the brainstem to repetitive acoustic stimuli. (05 Mar 2000) |
| automatic audiometry | An audiometric technique using an automatic audiometer, which enables the patient to track his own hearing thresholds by controlling the intensity of the signal being presented to him, while the audiometer sweeps through the audible frequency range. (05 Mar 2000) |
| Bekesy audiometry | Automatic audiometry utilizing the Bekesy audiometer; the patient makes two threshold tracings, one in which the tone is rapidly turned on and off (interrupted tone) and one in which the tone is presented steadily (continuous tone); results may be suggestive of middle-ear, cochlear, or eighth nerve lesions.
