Wide-band membrane absorbers shrink non-environment rooms to fifteen square meters

Evidence

These rooms require wide-band absorbers as shown in Figure 7.12. These absorbers can take up a considerable amount of space. As one can see in Figure 7.12, the absorbers can occupy more than 50% of the volume. However, it is possible to use wide-band membrane absorbers, as discussed in Chapter 6, with a structure similar to that shown in Figure 6.48 with a limp membrane in place of the perforated sheet. Using this type of absorber it is possible to achieve sufficient wide-band absorption with a depth of 30 cm, which allows this technique to be applied in much smaller rooms whose area is approximately 15 m2. — David Howard, Jamie Angus, coustics and Psychoacoustics, 2295
