Description
Hardwood Diffuser, 4" wide in varying lengths, used to produce a diffuse scattering of high frequency sound and control unwanted flutter echo. Grooved channels in the surface are a sequence of 7 elevations designed based on quadratic theory and the work of German acoustician M.R. Schroeder. Optional slotted back for adding sound absorption.
Composition
1" thick hardwood, type and finish selected by the designer. Typical length is a maximum 96" depending on the wood species selected.
Acoustical Performance
Unlike sound absorption testing (ASTM C423) and sound transmission control testing (ASTM E90), a test for sound diffusion does not exist in the American Society for Testing of Materials (ASTM) standards. The Audio Engineering Society has documented a test for diffusion characteristics. This information document, AES-4id2001 - was used to test HighTones Diffusers. The results indicate that sound diffusion begins to occur at approximately 3150 Hz and continues in higher frequencies throughout the audible spectrum.
Applications
Auditoriums, Lecture Halls, Music Performance and Rehearsal Spaces and other critical listening environments. Create high frequency clarity and acoustical brilliance without unwanted flutter echo.
Mounting
Attach with finish nails into wood furring behind each panel.
