Sound Pressure Levels

Due to the potential volume levels available with our FOH system that may come into the building with a show, the MFAC has adopted a very strict policy regarding SPL. The following maximum db level restrictions have been set for the protection of our audience members, crew, and artists. At no time shall the maximum A-weighted SPL ever reach above 110db at the Center of the House (COH) in Row 'EE.' MFAC reserves the right to direct their Head Audio Engineer or his designate to reduce system levels to remain within acceptable SPLs.

A-weight SPL @ COH Maximum Time

  • 95db 4 hours
  • 97db 2 hours
  • 100db 1 hour
  • 102db 30 minutes
