A boundary microphone (or pressure zone microphone) is one or more small omnidirectional or cardioid condenser mic capsule(s) positioned near or flush with a boundary (surface) such as a floor, table, or wall. The capsule(s) are typically mounted in a flat plate or housing.
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 room sound, such as in a conference room, by being mounted on a wall or table. When used to record a soloist or small musical ensemble along with the room acoustics (e.g. reverberation), a boundary microphone prevents phase interference between direct and reflected sound, resulting in a natural sound with a flatter frequency response than can be obtained with a stand-mounted microphone at the same distance (explanation below).
Examples of high quality Boundary microphones: MS-COURT-BOUNDARY, SP-USB-HG-BUNDLE, SP-USB-HG-BUNDLE-1, MS-COURT-BOUNDARY-XLR and SP-USB-BOUNDARY-1
