Speech Intelligibility in the multi-media conference room

For superior audio quality in multimedia conference system, it’s important

to calculate human voice, microphone, and loudspeaker

technical factors before installation

Multimedia conferences in Boardrooms can bring your meetings to life – integrating audience - engaging capabilities such as voice, video, graphics, and data into your presentations. But the design focus should be on your message speech intelligibility, not on the technology.

In order to design multi-media conference audiovisual technology integration that can deliver your message clearly, ALTA Integra always calculates the  following factors:

Human Voices Factors: speech level at normal to raise vocal effort (reference 60 dB to 66 dB at 1 meter), sound directivity, and distance to the microphone. Microphone Factors: Microphone sensitivity, directivity, and position. Loudspeakers Factors: loudspeaker level, directivity, distance to human ear and microphone to avoid audio feedback. Last but not least Acoustics Environment factors such as ambient noise and reverberation time.  

Integrating Architectural Building Physics knowledge such as Acoustic, Lighting, Thermal, Air Quality, and other disciplines play important role in making a better space for human-being. So let’s join our mission to share this belief and passion to make our world a better place.
