Advanced Calibration Plan (ACP)

The Acoustic Design Review (ADR) is a qualitative analysis of a system design and the System/Room Analysis and Measurement (SAM) is a quantitative measurement of performance. From each, the calibrator can draw conclusions about problems or potential improvements possible in a system redesign. After completing these reviews, if significant changes are needed, a further proposal can be created; the Advanced Calibration Plan (ACP). This plan in effect becomes a new design crafted to reduce or perhaps even eliminate a sonic objection. Basic calibration involves minor adjustments and changes. Advanced calibration involves larger changes designed to correct room acoustics or equipment shortfalls. The best calibrators will usually achieve good results with basic calibration techniques despite most common system or room limitations. Given the clients priorities and budget, the ACP is designed to tackle larger issues, specifies the cost of any major system redesign or more sophisticated calibration procedures. ACP is also needed when a room is being created or remodeled. Knowledge of acoustical properties should be used when designing a room. Overall, the Advanced Calibration Plan will specify the cost of any system redesign or calibration or detail requirements for proposal by others.

Common Plan Proposals:

  • precise positioning of listening chairs to achieve a smooth frequency response
  • precise positioning of speakers and subwoofer(s) for best response, clarity and sound stage presentation
  • rearrangement of furnishing to optimize acoustical value (sometimes moving a chair or bookcase can be as effective as buying an acoustical treatment)
  • redesign of wall surfaces, room dimensions, or addition of room treatments
  • addition or substitution of equipment such as sub woofers, speakers, amplifiers
  • proper equalization of sub woofers or in some cases all speakers
  • entertainment system cabinet redesign or modification
  • repair or upgrading of existing components
  • changes in furniture, wall coverings, window treatments, doors, insulation etc.
