Many audio conferencing systems employ beamforming microphone technology. Here we compare the characteristics of this traditional technology with Microphone Mist technology (only available in Nureva audio conferencing systems) for performance in small (up to 18' x 18'), mid-size (up to 25' x 25') or large (up to 30' x 50') rooms.
Microphone Mist technology – Microphone Mist technology provides true full-room coverage. It fills a room with thousands of virtual microphones (blue), so there is always a pickup point (virtual microphone) near every person in the room no matter how far apart they sit, where they move or which direction they face.
Beamforming – Audio is picked up within the beams (pink) that emanate from the mic array. Sounds in the dead zones outside the beams can be significantly suppressed or missed completely. Overlapping beams (if you choose to widen them for greater coverage) and beam transitions can cause signal confusion and poor audio.
Microphone Mist technology – Microphone Mist technology is flexible enough to meet the challenges of today’s meeting rooms. There’s always a virtual microphone nearby, even if people need to move around the room or sit far apart from each other.
Beamforming – People moving around a beamforming-enabled room may move in and out of the beams, which can make them hard to hear. Beam tracking technology, an evolution of beamforming technology, may help reduce this issue by directing beams to “follow” a person speaking. However, all sounds within the beam will still be amplified, which can make it difficult to hear the primary person speaking when there are competing sources.
Microphone Mist technology – Each sound in the room is isolated based on its position in the room. Thanks to advanced processing power, Microphone Mist technology listens to each virtual microphone simultaneously and zeros in on the predominant sounds (no matter where they come from in the room) and optimizes them for clear conversations.
Beamforming – A beamforming system picks sounds based on the direction a given beam is pointed. If multiple people are talking or other sound sources occur (e.g., HVAC) in a beam, they each receive the same level of gain, which can make the primary sound source hard to hear.
Microphone Mist technology – Microphone Mist technology listens to, and processes, all virtual microphones simultaneously. This results in quicker transitions and more complete pickup, so conversations sound natural.
Beamforming – A beamforming or beam tracking system must switch between beams to pick up two or more people talking. This delay in switching can cause beginnings and endings of phrases to be muffled or lost, which can make conversations hard to follow.
Microphone Mist technology – Nureva audio’s advanced processor focuses on the best sound source and defocuses room noises. Nureva audio systems also have intelligent sound targeting, a feature that uses adaptive learning algorithms to preemptively identify unwanted sounds (like HVAC) and simply stop targeting them.
Beamforming – Beamforming solutions for unwanted sounds, such as HVAC in ceiling vents, may entail modifications like separating the mic array from the HVAC, moving the HVAC or adding dampening material.
Microphone Mist technology – You can hang an HDL200 or HDL300 system on the wall yourself in 30 minutes or less, and the Dual HDL300 system takes about 60 minutes. There’s no need to bring in a technician for initial startup. And all three products feature continuous autocalibration that automatically adjusts the system so you can reconfigure a room as often as you need – Microphone Mist technology will simply adapt.
Beamforming – Installing an in-ceiling beamforming system can be costly and time-consuming. Reconfiguring a room will likely require a qualified technician to aim the beamforming lobes to the new seating positions.
Microphone Mist technology is only available in Nureva audio conferencing systems. Learn about the benefits of this revolutionary technology, including true full-room coverage, easy installation, continuous autocalibration and patented innovation.
