A boundary microphone is designed to rest on a table or flat surface. The flat surface becomes part of the microphone’s sensor. You place the microphone on a surface that becomes, in effect, a larger eardrum. The table helps to capture the sound of people conversing. A boundary mic is good for capturing a number of people who are, say, sitting around a table reminiscing about events.
It’s half-omni directional—picking up sound from all over the room in a half-dome above the table pickup pattern.
Advantages: Boundary mic is good for capturing sound from a group at a table.
Disadvantages: Boundary mics also pick up any activity on the table. Tapping, pounding table, bracelets or jewelery that strikes the table will be amplified.
