Acoustics+2



Achieving good auditorium acoustics is difficult because it requires a balance between dead sound and alive sound. This can be done using a combination of absorption and diffusion. The new trend in auditorium design is to create spaces which are large concrete boxes that have been decked (decoradas) out with sculpted wooden, plastic, metal, sheetrock (yeso) and sometimes even glass panels. Is very useful to cover the hall with curved panels that are suspended off the walls and again high overhead. The acoustic clouds are intended to adjust the signal to noise ratio in a direct and effective way.
