Acoustical Materials Acoustical Solutions AlphaSorb Get the best of both worlds: our AlphaSorb Barrier/Absorber Combination Wall Panel in combination

Acoustical MaterialsAcoustical Solutions AlphaSorbGet the best of both worlds: our AlphaSorb Barrier/Absorber Combination Wall Panel in combination with our Audioseal Sound Barrier. With a NRC of .85-1.05 and an STC of 29, you can achieve sound absorption and isolation without additional building construction. Panels available in sizes up to 4x10 feet and thicknesses of 1-1/8 or 2-1/8 inches. Covered in standard Guilford Fabric.

Acoustics First Corp. BassEraserThe BassEraser designers employed state-of-the-art particle propagation theory algorithms to evolve a truly new bass trap design. For typical applications, the standard broadband insert will solve most low-frequency problems. For correction of low-frequency anomalies, the BassEraser can be configured to create a tuned diaphragmatic bass trap. Stackable, trapezoidal enclosure mounts vertically or horizontally. Visible face cover is available in 48 Guilford of Maine FR701 colors.

RPG Diffusor Systems Room SizerThe first Windows program that automatically determines the best length, width and height for a room, given a range for possible lengths, widths and heights. Just enter the dimension ranges, and the optimum dimensions are determined. You can have the flexibility of choosing solutions for rooms that will use electronic equalization, or will not use electronic equalization.

RPG Diffusor Systems CATT AcousticsCATT acoustics is the industry's leading acoustical predication and auralization software. Room acoustics prediction is the process where using geometrical acoustics, octave-band echograms are predicted based on a 3D CAD model of a room. Frequency-dependent material properties (absorption, diffusion) are assigned to room surfaces, and frequency-dependent source directives are assigned to sound sources. Auralization is the process where predicted octave-band echograms are converted to binaural impulse responses that can be convolved with anechoically recorded speech or music giving an impression of how the music or speech would sound if replayed in the modeled hall.
