During your RRA assessment of a potential Cisco TelePresence System 1300 room you notice.
• The HVAC diffuser has noticeable noise (measured at48 1dB) which sounds like rushing air
What three recommendations should be made to the customer? (Choose three)
- The customer should turn the fan level down on the HVAC system to insure the fan noise is minimized in the Cisco TelePresence room
- The customer should contact an HVAC specialist to review and recommend an appropriate solution
- The customer should not worry about the HVAC fan noise because the Cisco TelePresence System uses a noise suppression algorithm designed to identify HVAC fan noise and minimize those frequencies
- The customer should replace the diffusers with a diffuser that is rated with a noise criterion of 10 or greater
- The customer should replace the ducting directly above the room with acoustically treated ducting to remove the sound of rushing airflow
