| Zusammenfassung | In general, airborne sound power is considered to be independent of direction, distance and environment. Nevertheless, for single tone or low frequency sound sources, the sound power emitted into rooms depends also on the environment and on the exact position in the room. This effect is investigated using Monte-Carlo-Simulations. It is then proposed to describe a source by the sound power that would be emitted into a free sound field. The consequences of this approach for measuring sound insulation are discussed. Page: 325-327 |
