BAD Panel

Combined absorber and diffuser

Kategorier: ,

RPG BAD panels combine absorption with diffusion and scattering.

Traditional absorbent panels absorb all the way to the highest frequencies, which may in certain applications lead to an overly dead and dry acoustic environment. The BAD Panel performs a diffusion starting at around 800 Hz and will therefore remain ambiance and energy to a greater degree. In addition, BAD panels give higher low frequency absorption than regular absorbents. BAD panels use an optimal binary pattern of perforations through a class A fire rated rigid template. The result is an excellent balance between sound absorption and diffusion and scattering, which gives an alternative to traditional purely absorptive fabric wrapped panels.
