None, exepct for a crazy hollogram imstument
A speaker is a device that converts electrical energy into sound waves through the movement of a diaphragm or cone driven by an electromagnet. This movement creates vibrations that produce sound waves that we can hear.
A microphone is a device that detects sound by converting sound waves into electrical signals. These signals can then be processed and used for various applications like recording audio or video conferencing.
A sonar device is commonly used to emit sound waves and measure the ocean floor. Sonar works by sending sound waves downward, which bounce off the sea floor and return, providing information about the depth and characteristics of the ocean floor.
A microphone is typically used to convert sound waves into electrical signals. The microphone's diaphragm vibrates in response to sound waves, which causes a coil of wire to move within a magnetic field, generating an electrical current proportional to the sound waves.
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.

I think its like sounds from a computer or a timer or something. Sound waves can be used to find out how deep a cave is before a construction can be done
sonar is a device used underwater for locating submerged objects and for submarine communication by means of sound waves.

Sonar (or Sound Navigation and Ranging) is a type of technology that was designed to help with navigation, communication and locate objects underwater. Sonar projects sound waves then listens for the echo of the emitted sound waves to detect objects.

what machine can be used to measure sound waves
sound energy can be transmitted from gases,plasma andliquids and as longitudinal waves, also called a compression waves. it requires a medium to propagate. through solids it can be transmitted as both longitudnal waves and transverse waves
computer
Sonar, which stands for Sound Navigation and Ranging, is used to locate objects underwater by sending and receiving sound waves. The device measures the time it takes for the sound waves to bounce off an object and return to the source, allowing for the calculation of the object's distance and direction. Sonar is commonly used in various applications such as navigation, fishing, and oceanographic research.
