• Recording Studios

Recording and Broadcasting studios will require minimum noise levels due to the nature of the working environment, with lower speed fans with silencers and acoustic linings more suited for these applications.

The general requirement is to provide a comfortable environment within the constraints imposed by the production of music and broadcast programs. Specific issues that need to be addressed include:

  • High lighting loads in studios
  • High occupancies for shows with audiences
  • Rapid changes in load
  • Variable operation times, periods and multiplicity of studio arrangements
  • Sensitivity to air movement and noise
  • High equipment loads in technical areas
  • Critical areas requiring a high degree of reliability and 24 hour operation
  • Adaptability to respond to changing technological and business requirements.

Mechanical ventilation systems for recording and broadcasting studios need to provide a high level of reliability, as the ventilation system is critical to the functioning of the building.

Television studios may have 2-3 lighting rigs to suit different requirements. For programs such as news and current affairs, which will have less need to create visual interest and that run all day, fluorescent lighting may be used in addition to tungsten, thereby reducing lighting load , these factors highlight the need for appropriate ventilation design.

Variations in heat loads is an element of ventilation design that should be taken into consideration. Game shows duration is between 30 minutes to an hour, during which time, lighting may be brought up and down on the audiences. In drama studios, there are a number of sets that may be fully lit at any one time. Setting up studios for shows can take several days, during which time loads will be low.

Humidity control in recording and broadcasting studios can be challenging due to the swift load changes. Vigilance of tape storage areas is needed to reduce potential deterioration, although preferable that tapes are stored under the same environmental conditions as the room in which the tapes are to be used, which minimises sticking and problems occurring due to static electricity.

As in other applications, background noise from a ducted air system provides a degree of masking of unconnected noise in adjacent areas. If background noise levels are substantially lower than the criterion set, then unconnected noise normally masked by the ventilation could become apparent.

Elta Fans provide a wide range of ventilation products tor recording and broadcasting studios, with particular emphasis placed on providing acoustically lined fans, so for more information, please look at examples of typical products that could be used for these applications, or alternatively, please contact us to discuss your specific application requirements.
