sonometer

A doctor uses a sonometer to test a patient's hearing.

Definition
  1. Noun:
    • An instrument for measuring hearing sensitivity: A device used in audiology and acoustics to test and quantify the sensitivity of a person's hearing, often by presenting sounds at various frequencies and intensities.
    • An instrument for measuring sound frequencies or vibrations: In physics, a sonometer can also refer to an apparatus, typically consisting of a wire stretched over a sounding board, used to demonstrate the relationship between the frequency of a sound and the tension, length, and mass per unit length of the vibrating string.
Usage Examples
  • Noun:
    • The audiologist used a sonometer to determine the patient's precise hearing thresholds.
    • In the physics lab, we calculated the frequency of the wire's vibration using a sonometer.
Advanced Usage
  • Clinical Application: In a medical context, a sonometer is a key tool for conducting audiometric tests to diagnose hearing loss.
    • The results from the sonometer were plotted on an audiogram.
  • Experimental Physics: Used to verify Mersenne's laws of vibrating strings.
    • The experiment required adjusting the tension on the sonometer's wire while keeping its length constant.
Variants and Related Words
  • Audiometer (n): A more specific, modern type of electronic instrument used for measuring hearing acuity. While often used interchangeably in some contexts, "audiometer" is the standard term in clinical audiology.
  • Monochord (n): A historical and musical instrument similar to a sonometer, consisting of a single string stretched over a resonating body, used for tuning and demonstrating musical intervals.
Synonyms
  • Audiometer: An instrument for measuring hearing acuity. (Note: This is a near-synonym, but "sonometer" can have a broader physical acoustics application.)
  • Acoumeter: An older term for an instrument used to test hearing.
Related Phrases and Compounds
  • Sonometer reading: The measurement or data obtained from using a sonometer.
    • The sonometer reading indicated a mild high-frequency hearing loss.
