ACOUSTICS: REFLECTION MODULE
Reflection Free Zone & Diffuse Field Zone
At this stage, we have optimized the modal response up to the transition frequency between wave and geometrical acoustics (referred to as the Schroeder frequency). If you would like to optimize the frequency range above the transition frequency, we offer the Specular Reflection Module.
This module optimizes the two design criteria proposed by Dr. Peter D’Antonio, three decades ago, which have withstood the test of time. This is referred to as the RFZ/DFZ design.
The Reflection Free Zone (RFZ) refers to the time between the direct sound and the first arrival from the rear of the room, and it is ideally between 20 and 30 dB below the direct sound. Treatments applied to control the first order interfering reflections are positioned to satisfy this criterion. It ideally extends from the highest frequency all the way down to 125 Hz, but it depends on the broad bandwidth absorption control of the employed treatments for mid and high frequencies and the splaying and length of the front side walls for lower frequencies. The RFZ is essential to create a real stereo image.
The Diffuse Field Zone (DFZ) begins at the arrival of the rear wall reflection and is characterized by being a zone of high temporal density, typically created with reflection phase gratings diffusors. The DFZ typically extends down to 500 Hz and can be extended below that if a modulated fractal design is employed in the application of the diffusors. The DFZ is essential to create envelopment at the listening positions.
ARCHITECTURE & AUDIO
We conclude the optimization by reviewing the client's final design to determine if any acoustical modifications are necessary.
Following this step, REDI Acoustics provides a final report as the deliverable. The report is your guide to optimal acoustical performance without altering the direct sound.
It enables the reproduction system to be tuned to preference without being hindered by any acoustical issues that will prevent it from operating with its full potential.
