A hydrophone is the instrument commonly used to measure sound underwater. It works by converting sound waves into electrical signals that can then be analyzed and recorded. It is a vital tool in various fields like oceanography, marine biology, and underwater acoustics.
An echocardiography is performed using an ultrasound machine that sends high-frequency sound waves into the chest area to create images of the heart's structure and blood flow. This machine uses a probe that emits the sound waves and captures the echoes bouncing off the heart.
A telephone is an instrument that sends voices using electricity. Sound waves are converted into electrical signals, transmitted through wires or wireless networks, and then converted back into sound at the receiving end, allowing people to communicate over long distances in real time.
Pitch is another name for the frequency of sound waves . . . that is, how close the waves are together. Pitch is a term usually used in terms of music.
A seismometer is the instrument used to measure waves, such as seismic waves, within the Earth. This device detects and records the vibrations caused by seismic events like earthquakes. Seismometers are essential tools for studying the structure and properties of the Earth's interior.
A microphone is an instrument used to capture and magnify sound by converting sound waves into electrical signals.
Most modern systems use audio electronic amplifiers. The old horn type hearing aid would concentrate sound.
an amplifier
A device called a echo sounder or sonar is used to measure the depth of the ocean using sound waves. Sound waves are emitted from the instrument and the time taken for the sound waves to bounce back from the ocean floor is used to calculate the depth.
An Amplifier is used to increase the volume of an electrical musical instrument by boosting the signal of the instrument and "amplifying" it through a speaker system.

Acoustic mirrors were used in the early 20th century as early warning devices to detect approaching enemy aircraft by reflecting and amplifying sound waves. They were part of experimental sound detection systems before the invention of radar technology.
what machine can be used to measure sound waves
The microphone belongs to the family of devices known as electroacoustic transducers, which converts sound waves into electrical signals. It is commonly used for recording and amplifying sound in various applications such as music, broadcasting, and communications.
The phonograph is an early device used to record and play back sound. It works by using a needle to trace sound waves on a rotating disk then amplifying them through a horn. Invented by Thomas Edison in 1877, the phonograph revolutionized the way music and other sound recordings were produced and enjoyed.
