Sound calibrators are used in an identical way to pistonphones, providing a known sound pressure field in a cavity to which a test microphone is coupled. Sound calibrators are different from pistonphones in that they work electronically and use a low-impedance (electrodynamic) source to yield a high degree of volume independent operation.

Microphone technique—how to say it into a microphone; These procedures have been developed, tested under the most difficult of conditions, then revised to implement the lessons learned, many times since the early 1900s [clarification needed]. According to ACP 125(G) [2] and the Virginia Defense Force Signal Operating Instructions: [4]
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] The diaphragm of the microphone responds to changes in air pressure caused by sound waves. That is why the instrument is sometimes referred to as a ...
The boundary microphone can be used as a piano mic by placing it inside the piano lid, an approach which can obtain better pickup of the piano's mix of sharp percussive transients and gentle undertones than other microphone options. Boundary mics are used on hockey boards for body check sound effects. They are also commonly used to record full ...

The carbon microphone, by virtue of using a power supply, gives a power gain. This can readily be demonstrated by connecting a battery, microphone and earphone in series. If the microphone and earphone are brought in contact the system will oscillate. This is only possible if the power gain around the loop is greater than unity.
