Abstract:
An algorithm for auralisation of sound insulation in buildings was developed. It allows modelling of the influence of sound transmission paths through building structures and of the receiving room. One-third octave band sound insulation data of building products are used as input data to synthesize a transfer function from the source room to the receiving room. Any desired monophonic signal can be processed with this transfer function to obtain the sound impression in the receiving room. The auralised sound gives a natural binaural impression both concerning loudness and coloration. The software is running under Windows 95/98/NT. Generation of a receiving room signal requires in total 10 seconds on a Pentium II PC with 233 MHz. Sound reproduction is performed by any plug-in PC sound card.
