| 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) |
| Bekesy audiometer | An automatic audiometer in which the tone sweeps the audiometric scale while the patient controls intensity by pressing a button when he cannot hear the tone; may be operated either at a fixed frequency or at steadily changing frequencies. (05 Mar 2000) |

| self-limited disease | A disease process that resolves spontaneously with or without specific treatment. (05 Mar 2000) |

| sex-limited inheritance | Inheritance of a trait that can be expressed in one sex only, e.g., testicular feminization. (05 Mar 2000) |
| speech audiometer | An audiometer that provides spoken material at controlled sound pressure levels to obtain speech reception thresholds, tolerance for loud speech, and discrimination ability, utilizing either a live voice with a microphone or a recorded voice played over a turntable or tape recorder.

| limited habitat | A habitat type that is rare or has been significantly reduced from its historical distribution, either locally or statewide, and is of special importance meeting the general life requirements of many wildlife species. (09 Oct 1997) |
| range | The set of conditions throughout which an organism (for example, plant species) naturally occurs. (09 Oct 1997) |
| range, normal | Normal results can fall outside the normal range. By convention, the normal range is set to cover ninety-five percent (95%) of values from a normal population. Five percent (5%) of normal results therefore fall outside the normal range. (12 Dec 1998) |
| range of accommodation | The distance between an object viewed with minimal refractivity of the eye and one viewed with maximal accommodation. (05 Mar 2000) |
| range of convergence | The distance between the near point and far point of convergence. Synonym: range of convergence. (05 Mar 2000) |
| range of motion | The range through which a joint can be moved, usually its range of flexion and extension. Due to an injury, the knee may for example lack 10 degrees of full extension. (12 Dec 1998) |
