This option may be required when a more controlled sound environment is needed in the host room. 

Exterior ventilation fans have a 38dB noise rating. This slight noise can be eliminated by positioning each fan into an Exterior Fan Silencer (EFS). The number of EFS units needed depends on the size of the WhisperRoom™ and the number of ventilation systems required.
