What is a Boundary Layer Microphone?

A boundary microphone, also known as a pressure zone microphone or PZM mic, is a small diaphragm condenser mic capsule that is mounted into a housing to lay on or attached to flat surfaces that are sturdy enough to experience fewer falls. These microphones are typically compact but can record great distances, usually with a cardioid or supercardioid polar pattern. 

Pressure zone microphones are used for picking up multiple audio sources in a room. Ideally, the best place to put a boundary microphone is on a flat area, like a wall or a table. This is because it is made specifically to pick up sound that is reflected off the desired surface it’s on. 

Many premium quality 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.

What are Boundary Mics Good For?

Pressure zone microphones are designed to capture audio within a specific area, making them a versatile choice for a variety of applications. PZM microphones are good for:

  1. Conferences and meetings. Premium microphones capture high-quality audio, improve speech intelligibility and reduce background noise.
  2. They are also used by music artists to record audio in any room sound. As these mics provide a crystal clear sound, artists can perform using acoustic instruments easily.
  3. Capturing audio for live events, performances, or on-stage presentations, delivering high-quality audio, and amplifying sound for audience members. This is perfect for a pressure zone mic that has a great frequency response.
  4. Sound reinforcement. They enhance the audio quality of video recordings, providing clear and natural sound for video content. Using a condenser pressure zone mic provides much better sound optimization. 
  5. Providing directional audio pickup in noisy or reverberant environments, reducing ambient noise and room reflections. Users with good control ideas can gain control of the different sounds that the mic captures, significantly lowering unwanted sounds.

Do Boundary Mics Need Phantom Power?

A condenser pressure zone mic requires a phantom power supply 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.

Frequently Asked Questions

While a pressure zone mic works fantastically for indoor settings, it may not be as reliable outdoors. Instead, consider dynamic microphones which can capture the speaker while controlling ambient noise effectively.

Which mic is best for distance?

A shotgun mic is one of the best microphones for capturing audio from a distance, as they have a directional pickup pattern and are able to focus on a specific source of sound while rejecting background noise.

What type of mic is best for dialogue?

Dynamic microphones with an omnidirectional pattern are great for recording dialogue in outdoor settings. For indoor recordings, a large-diaphragm condenser mic works well.

Final Note

Whether you’re a public speaker, working in conference calls, or performing music, pressure zone microphones are a fantastic and relatively inexpensive means to record larger spaces with high-quality sound. It can be difficult to determine which mic is the best. Fortunately, if you’re on the hunt for a new mic that can serve you multiple or specific purposes, we decided the top ones for you! This list has more than a handful of microphones you can choose from at costs you can afford.
