Definition of acoustic thermometry
- Because sound travels faster in warm water than in cold, this method, called acoustic thermometry, could provide a precise method of taking the ocean’s temperature, they reasoned.

- The acoustic thermometer works by transmitting sound waves along a gas-filled tube from a speaker at one end to a microphone at the other. By measuring the amount of time it takes the sound waves to travel along the tube, the temperature can be calculated.
