To have constructive meetings it is important that we hear each other clearly; everybody should be able to easily follow and participate in the conversations, presentations and discussions. However, it is also important to prevent the sounds of the meeting from spreading to others in the office.
A meeting room is almost always furnished with lots of equipment, such as humming projectors and speakers for telephone and video conferences. At the same time there are often two glass walls and a third that has the obligatory whiteboard. Speech will bounce off all these hard surfaces, creating echoes that obscure speech.
To keep sound from entering and leaving the space, to ensure speech clarity by preventing wall-to-wall echoes and low-frequency disturbance.
Superior sound insulation, a sound-absorbing ceiling with good absorption qualities at low frequencies and wall absorbers covering at least one wall, but preferably two adjacent walls.
