The Sound of Silence: beamforming and the importance of what is not heard
STIM Tech Bites: thematic pills on news, trends and curiosities related to the AV & Modern Workplace market, on the occasion of ISE 2024 - AUDIO
In the digital age, where sound compression and streaming are incredibly sophisticated, we expect ahigh quality audio experience that allows us to hear and be heard optimally, without disruptive elements. This need is especially relevant in meeting rooms, where clarity of communication is paramount.
Technology comes to the rescue in this regard: beamforming is a signal processing technique for directing the sound waves of a microphone system to capture sound from a specific direction, excluding unwanted background noise.
Beamforming: how it works
Beamforming uses microphone arrays that work together to focus on a specific sound source-for example, a speaker in a meeting room-while simultaneously attenuating sound from other directions. This means that participants can be heard clearly even in noisy environments, significantly improving the quality of remote communications, such as video and teleconferences.
Not just background noise: beamforming and soundproofing specific areas
In addition, beamforming can be used to "draw" zones of silence, where microphones are programmed to ignore sounds from certain areas of the room. This is particularly useful for excluding disturbing noises such as air conditioning, computer keyboards or side conversations, which can distract or interfere with the meeting.
In conclusion, the adoption of this technology in meeting rooms leads to a more acoustically controlled environment where communication is more effective and participants' attention can remain focused on the topics discussed.
In the modern business environment, where meetings often include remote participants connecting from various parts of the world, ensuring clear and interference-free audio transmission is essential for successful collaborations and business decisions.When planning, therefore, it is highly advisable to consider not only design, furniture and hardware, but also the acoustic study of the space in order to choose the appropriate technology.
