| Abstract: | Acoustical requirements and the design approach of a digital audio laboratory is presented in this paper. The main efforts are given to frequency spectrum of reverberation and sound field diffusion due to the special acoustic characteristics of a small room. Noise abatement measures are taken to achieve a low level of background noise. Field measurements and subjective evaluation show that acoustics in the digital audio labratory has the desired effects. |
