| time-varied gain control | In ultrasonography, an increase in receiver gain with time to compensate for loss in echo amplitude with depth, usually due to attenuation. Synonym: attenuation compensation, depth compensation, time compensation gain, time-compensated gain, time-varied gain control, time-varied gain. (05 Mar 2000) |

| automatic | 1. Having an inherent power of action or motion. "Nothing can be said to be automatic." (Sir H. Davy) 2. Pertaining to, or produced by, an automaton; of the nature of an automaton; self-acting or self-regulating under fixed conditions; especially. Applied to machinery or devices in which certain things formerly or usually done by hand are done by the machine or device itself; as, the automatic feed of a lathe; automatic gas lighting; an automatic engine or switch; an automatic mouse. 3. Not voluntary; not depending on the will; mechanical; as, automatic movements or functions. "Unconscious or automatic reasoning." (H. Spenser) Automatic arts, such economic arts or manufacture as are carried on by self-acting machinery. Origin: Cf. F. Automatique. See Automaton. Source: Websters Dictionary (01 Mar 1998) |
| automatic audiometer | An audiometer that is operated by the patient, enabling him to control the intensity of the tone presented to him and thus track his own hearing thresholds. (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) |
| automatic beat | In contrast to forced beat, an ectopic beat that arises de novo and is not precipitated by the preceding beat; thus escaped and parasystolic beat's are automatic. Synonym: automatic contraction. (05 Mar 2000) |
