The best auditorium seat is composed of a chair, a chair back, an arm rest and a standing foot. Under normal conditions, the standing foot and arm rest will produce a solid arm rest structure, which is generally composed of steel and wood structure or rigid plastic structure.
The best auditorium seats are suitable for the auditorium, theater, theater, lecture hall and other such places. They provide a good view during the conference and performance period. The best auditorium seats should be convenient for maintenance and cleaning. They should be comfortable and not easy to get tired when used. In most cases, the fabric sofa type cushion is used, in order to better facilitate people to disperse their concentration when leaving the field, and the cushion can be rotated back. The best auditorium seats in the auditorium should take into account the serial number of the best auditorium seats and local lighting fixtures, so that customers can identify and find the best auditorium seats. According to the needs of application software and on-site solutions, the best auditorium seats in the auditorium need to place documents and writing boards for recording. In particular, the auditorium also needs the integration of logical thinking and simultaneous interpretation machines and equipment, as well as network voting and video voice machines and equipment; Some theatres or auditoriums also need seats and air conditioning units to cooperate with each other.
The temperature and ambient humidity of the best auditorium seats in should be suitable. Generally, the indoor temperature is 18-25 ℃, and the ambient humidity is 60% - 80%. In order to ensure proper room temperature and ambient humidity, air conditioning system software can be installed in the auditorium to complete heating, humidification, refrigeration and natural ventilation. The auditorium provides fresh air, and the ventilation volume of each person per hour is not less than 18 cubic meters. The noise level of the auditorium is set at 40dB (A) to form an excellent natural environment. If the room is noisy, such as air conditioning noise, it will greatly harm the characteristics of the sound system.
Lighting design and lighting regulation: indoor lighting is the basic regulation of the video auditorium. Because the videoconference is held at will from beginning to end, the artificial synthetic cold light lamp shall be used in the room to avoid sunlight. The windows and doors of the auditorium should be covered with dark brown window cloth. The light source does not harm the vision of the eyes of the people. Three natural colors (led color temperature 3000-3500K) are more suitable. In order to ensure the accurate image color and camera self-balance, please judge that the light directly shining on the face of the participants should be uniform, and the light intensity should not be less than 500lux. The light intensity around the display screen and projection TV is 50-80 lux, and direct light should be prevented. The orientation of the light is more critical than the intensity of the light. The lens used to spread the light can fully spread the light and make the face of the participants be evenly lit.
The tricolor lamp is generally installed on the ceiling of the auditorium, the L-shaped structure should be installed on the ceiling, and the led lamp tube should be installed at the corner of the L-shaped structure, so the light is not easy to immediately shine on the objects and participants, but only depends on the reflection and transmission of the light on the ceiling, lighting the auditorium.
In addition to the above two points, in order to achieve good practical results, we also need to pay attention to: avoid the sun from shining on the best auditorium seats, the situation and the camera lens, in order to prevent glare and obvious gap. Avoid the headlights and side lights coming from the outside of the window from lighting up immediately. Such lighting will immediately lead to dark shadows. Apply auxiliary lights, advocate the use of fluorescent lights, avoid the use of colored plate lighting effects, and prohibit the use of flash photography flash. It is recommended to use immediate light source or reflect mild light from flat wall. It is suggested to use auxiliary light when the light is very weak, but direct exposure should be avoided.
