Did you know that room size is an important aspect when buying a conference phone? Room size can impact the success of a conference call, especially the audio quality. Therefore, it is important to know which product is right for you and your company and if you need to buy additional accessories. Conferencing is becoming more and more popular amongst businesses due to its many benefits. It can also help with plans for growing your business further. For example, it can help improve efficiency and productivity; thus ensuring better communication between employees and employers. The information below offers advice about conferencing based on different room sizes, complete with recommendations for each size room.


Small rooms

Up to 4 people
Room size (approx.): 12′ × 10′
Recommended microphone coverage: 5-7 feet

This room could be a home office, a small work office or small conference room. Due to the small size of the room, the participants are close to the microphones and also the loudspeaker. Therefore, this ensures excellent sound quality for both parties. In addition, the small size and furniture in the room limits the possibility of echo noise.
