Best Boundary Microphones: Top 10 Models and Brief Review!

Introduction

A boundary microphone (or pressure zone microphone) is a number of small omnidirectional or cardioid condenser mic capsule(s) positioned close to or flush with a boundary (floor) similar to ground, desk, or wall. The capsule(s) are sometimes mounted in a flat plate or housing. The association offers a directional half-space pickup pattern while delivering a comparatively phase-coherent output signal.

The boundary microphone can be utilized as a piano mic by inserting it inside the piano lid, a strategy that may acquire a higher pickup of the piano’s mixture of sharp percussive transients and delicate undertones than different microphone picks. Boundary mics are used on hockey boards for body examination sound results.

When used to record a soloist or small musical ensemble together with the room acoustics (e.g. reverberation), a boundary microphone prevents phase interference between direct and mirrored sound, leading to a pure sound with a flatter frequency response than will be obtained with a stand-mounted microphone on the identical distance.

Boundary mics are normally inexpensive than different mics, though there’s nonetheless a variety of worth factors that varies, relying on the variety of capsules and the absence or presence of further options, similar to on-off switches, wireless capabilities, and levers to reposition the capsule(s).

We just want to let you know that we’ll list these Boundary Microphones reviews in no particular order. They’ll be randomized as we don’t wish to sort them from best to worst.

Listed below are our Top 10 Boundary Microphones:

Conclusion

The boundary microphone, additionally known as a pressure zone microphone or PZM microphone can present superb efficiency for a number of purposes. Boundary microphones are sometimes used with pianos which are usually tough to record successfully.

They’re additionally usually mounted on partitions to file a full room sound. They might even be used to file music in a room together with the room acoustics. Via its operation, the boundary microphone can forestall phase interference between the direct and mirrored sound, and this leads to an extra pure sound.

It’s discovered that for a 1dB discount in acoustic loss, the gap between the boundary and the microphone diaphragm has to be only 1/13 of a wavelength. In actual phrases, this equates to a distance of solely 0.13 centimeters for frequencies of 20kHz on the high of the usually accepted frequency vary. Then for a 3dB drop, the gap has to be lower than 1/8 wavelength which equates to 0.22 centimeters.

Boundary mics have a comparatively flat profile, they’ve got the benefit of being much less visually obtrusive, resembling when they’re positioned on a convention desk or the ground or a musical theater stage.
