Acoustic Design Review (ADR)

Everyone wants a little advice on getting the best sound in their home theater and advice is usually worth the price you pay for it. In the case of an HAA Trained Technician's ADR, their advice is based upon many years of professional experience, supported by the resources of the Home Acoustics Alliance. The Acoustic Design Review (ADR) is our opinion of your system or room but it is based on the training of an alliance of professionals. It is a qualitative analysis of a system design. It is the first half of a complete system review and calibration. The ADR process begins with a site survey of your listening room in person or via detailed drawings. The process continues with a short but very thorough analysis of the design. We review every relevant element of system design in the context of desired acoustical goals.

These goals include:

• Clarity: Clear understandable dialogue, low level sonic detailing.
• Focus: Localization of sounds within the front sound stage.
• Impact: Dynamics: dynamic contrast, clarity even when at peak sound levels.
• Smooth Response: Minimize the booms, ringing and shrills, correct timbre.
• Sonic Envelopment: Smooth front to back panning, swimming in sound.
• Large Sweet Spot: Each listener should hear the above qualities

Every element of your current system or proposed system is reviewed for suitability. The HAA ADR is designed to be a "sanity check" to make sure your expectations of sound quality will be met for a proposed system or how to improve an existing one.

The final report is a concise list of recommendations by the calibrator for proposed modifications to the design. The ADR is not a guarantee of great sound nor does completing the ADR function as a calibration of your system. Rather, it is the first step in creating a calibration plan to be accomplished separately by the calibrator, or by you. Each ADR is authored by the individual technician, and will be explained in detail by that technician.
