In some teaching spaces you may find boundary microphones.

• These are microphones placed flat on a desk or table.
• They are designed to pick up sound from people standing or sitting nearby, such as during group discussion or seminars.
• They rely on their position on a flat surface to work effectively.

Important things to know:

• Boundary microphones are strategically positioned to capture sound correctly.
• They must not be moved, covered, or unplugged.
• Moving them can significantly reduce audio quality or stop them working as intended.

You may not notice these microphones immediately, as they are often unobtrusive and do not look like traditional handheld or lapel microphones.
