a Sound Pressure Level Meter is used to measure sound levels.See related link.
Sound level meters Loudness meters Noise dosimeter
Used to measure earthquake activity with sound waves.
A frequency meter is the instrument that is used to measure the amplitude of sound. It reads the energy from a sound wave.
A microphone is an instrument that uses electricity to measure sound waves. It converts sound waves into electrical signals that can be amplified, recorded, or processed by electronic equipment.
A decibel meter, also known as a sound level meter, is used to measure the loudness of sound. It quantifies the intensity of sound in decibels (dB) and can be used to assess noise levels in various environments.

A sonar instrument emits sound waves to measure the ocean floor. The sound waves travel through the water and bounce back when they hit the seafloor, allowing the instrument to calculate the depth and map the topography of the ocean floor.
A decibel is a unit used to measure the intensity or loudness of sound. It is a logarithmic scale that compares the sound pressure level to a reference level. The higher the decibel level, the louder the sound.
Audio Analyzers are instruments that test and measure instrument audio performance. They are used as a way to measure the quality and sound of a specific instrument.
You measure the sound pressure with a sound pressure level meter (SPL meter).
The measure of the loudness or intensity of sound is called decibels (dB). It quantifies the level of sound pressure that is perceived by the human ear. The higher the decibel level, the louder the sound.
