A boundary microphone is a type of microphone that is designed to be placed on a flat surface, like a wall, floor, or table. This design allows the microphone to pick up sound in a unique way, leveraging the surface it's placed on to capture sound more effectively.
These microphones are known for their ability to produce a clear, natural sound with less phase interference and noise. This is because they are placed on a surface, which reduces the number of reflective sound paths.
