Narration and host environments should be cool, dry, and well ventilated. The air supply should be well filtered because clean air is important for the comfort and well-being of production staff, as well as for reliability of mastering and review equipment.
Most enclosures used as narration environments are not connected to the heating, ventilating, and air-conditioning system of the building but have a ventilation system mounted on the enclosure's exterior. This system uses fans to pull air from the host environment, move it through the enclosure, then exhaust it back into the host environment. Temperature and humidity inside the enclosure are maintained at the ambient temperature and humidity of the host environment, provided there is adequate air flow through the enclosure.
The quality of lighting in narration and host environments is important because the work of narrators, monitors, and reviewers is sight intensive, and many problems with print quality can be ameliorated with good lighting. Full-spectrum light is recommended when working intensively with print material for an extended period of time.
