2. Sound level meter - Wikipedia

   en.wikipedia.org/wiki/Sound_level_meter

   A sound level meter (also called sound pressure level meter (SPL)) is used for acoustic measurements. It is commonly a hand-held instrument with a microphone. The best type of microphone for sound level meters is the condenser microphone, which combines precision with stability and reliability. [1]

3. Spectral noise logging - Wikipedia

   en.wikipedia.org/wiki/Spectral_noise_logging

   Spectral noise logging (SNL) is an acoustic noise measuring technique used in oil and gas wells for well integrity analysis, identification of production and injection intervals and hydrodynamic characterisation of the reservoir. SNL records acoustic noise generated by fluid or gas flow through the reservoir or leaks in downhole well components.

4. Data logger - Wikipedia

   en.wikipedia.org/wiki/Data_logger

   A data logger (also datalogger or data recorder) is an electronic device that records data over time or about location either with a built-in instrument or sensor or via external instruments and sensors. Increasingly, but not entirely, they are based on a digital processor (or computer), and called digital data loggers (DDL).

5. Acoustic Doppler current profiler - Wikipedia
