| Enclosure Design Rule #2: Ventilation |
 |
Heat build-up inside acoustical enclosures can be dissipated using forced ventilation fans and blowers in a draw through (see right) or blow through design. The intake and discharge of forced ventilation systems must be acoustically treated with louvers, lined baffles, hoods or duct silencers. The owner or designer of the enclosed equipment needs to determine what is sufficient air flow to dissipate heat. The formula at left is a good guideline. Proper placement and location of intake and discharge openings should ideally bring in air low on one side or end of the enclosure and draw air over the equipment before exiting high on the opposite end or side. |

| Enclosure Design Rule #3: Access |
  |
Removable panel sections (bottom left) can allow for infrequent maintenance access in a limited area. Hinged doors (at right) provide for more frequent access but require clearance for the door swing outside the enclosure. Sliding doors (see left) also provide easy access without protruding into work area space outside the enclosure. Acoustical performance of sliding doors is less than that of hinged doors. Double doors provide access to a larger area. Sliding or removable roof panels and sections are best for major repairs requiring a crane. Small enclosure designs can be a knock down design where all panels are latched together for quick and easy disassembly. |
