| Useful Tips | 1. If you plan to perform video in a big room, use a wide screen video projector. There are projectors mounted into the ceiling. They can be very beneficial but you should perform the movable regime of such a facility. A portable LCD projector works fine for medium sized groups (the number of students may not extend 25), and it’s possible to move it from one class to another.
2. When choosing the performing computer or audio-video equipment, try to purchase Multiscan units if you have at least some spear money. Multiscan projectors and monitors can display satellite and TV programs and computer (VGA, SVGA, Macintosh) images.
3. Relationship of the projector screens and TVs to the lighting is also important. Light should not cause glare, reflections on TV screens or washout images on projection screens.
4. Whiteboards should also have no more than 50% reflectance so as to not cause glare to the cameras or participants. A light grey, beige or cream color would be preferred over stark white.
5. Ambient noise level measured in any of the eight octave bands from 20 Hz to 10,000 Hz shall not exceed NC-30 when the unoccupied room is in normal operation with all ventilation systems and machinery running, including those in adjacent spaces.
6. Sound transfer coefficient (STC) shall be greater than or equal to STC.
7. Reverberation RT-60 shall be less than or equal to 500 milliseconds.
8. Do not locate your classroom next to noise generating equipment and spaces such as mechanical rooms, toilets, elevators, etc. However, public facilities, such as rest rooms and vending should be conveniently located.
9. There are special telephone lines where you can access if you need some help. The consultants will assist you in your particular equipment problem.
10. Staff offices usually do not need as much wiring and other treatments as a classroom, but will need to have at least two voice and data jacks in each single occupant office to allow flexibility in furniture placement.
