Acousticians & Audio Engineers on Sound Performance in a Room
What ACOUSTICIANS and AUDIO ENGINEERS said about RELATIONSHIP between ROOM DESIGN and AUDIO PERFORMANCE?
Produce or listening music with a realistic sound performance is a dream of every musicians, sound engineers and music or audio lover.
“Although it has been traditional to consider the loudspeaker and room as separate entities, this approach is no longer justified. The loudspeakers, room and listener comprise a system within which the sounds and spatial illusions of stereo are decoded, and they must be considered together.”
Jan Abildgaard Pedersen, 1994
Bang & Olufsen, DynAudio
Increasing the reverberation time tends to decrease the position sensitivity, especially at higher frequencies. This is, as expected, due to the fact that the sound field becomes more diffuse when the reverberation time increases. The sound pressure amplitude does not depend on the position in a perfectly diffuse sound field.
David Griesinger, 1998

In rooms where low-frequency envelopment is perceptible, low-frequency instruments in classical music are often perceived as external, while Iow-frequencies in popular music are often "in the head". Low-frequency instruments in popular music, such as the kick drum and the bass guitar, are almost always perceived as coming from inside the head.
Avis, Fazenda, Davies, 2007 Salford University
Given the suggestion that the high-frequency reverberation time may help “mask” low-frequency problems.
“Remember, dollar for dollar the acoustical treatment of your room will make more of an audible difference than any piece of electronic hardware, speaker, or cable.”
ALTA Integra is a multi-discipline building physics engineer designer such as acoustics sound, lights, thermal, air quality, and etc. Research agreed that the built environment is affecting the sensor, emotion, behavior, and biology of humans and other living objects. Our mission is to create a greener, healthier, beauty and comfort to lives in.

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.
