What is a Boundary Microphone Used For?

A boundary microphone, also known as a pressure zone microphone, is a small diaphragm condenser microphone capsule that is mounted into housing to lay on or be attached to flat surfaces. These microphones are typically compact but can record great distances, usually with a cardioid or super-cardioid polar pattern. 

Boundary microphones are used for picking up multiple audio sources in a room. The flat surface that it is placed on, like a wall or table, is ideal because the best boundary microphone is made specifically to pick up sound that is reflected off the surface it’s on. 

These microphones are most commonly found in settings like business meetings, but they can also be seen in other applications such as churches, sports (like hockey boards for body check sound effects), small musical ensembles, stage presentations, and more.

Frequently Asked Questions

Do boundary mics need phantom power?

A condenser boundary microphone requires phantom power to function, as the mic needs current to create a voltage that powers the internal circuitry, unlike dynamic and ribbon mics which make their own current.

Which microphone is best for outdoor recording?

While boundary microphones work fantastically for indoor settings, they may not be as reliable outdoors. Instead, consider dynamic microphones which are able to capture the speaker while controlling ambient noise effectively.
