| Zusammenfassung | The standard ISO 717 is the main link between measured or predicted sound insulation spectra in buildings and legal requirements. It provides the procedures to evaluate representative single-number values from given frequency spectra of sound insulation. At an ISO meeting a few years ago, the wish came up to reduce the large variety of selectable quantities. Thus, a simplified and more straightforward system of single-number quantities was proposed which is now discussed in the corresponding standardisation working group of ISO. The main features of the proposal are the mandatory inclusion of frequencies below 100 Hz, the deletion of the reference-curve shifting system (as used for Rw e.g.), the expression of impact sound insulation in terms of a sound reduction index as well, and a new sound reduction index especially for speech intelligibility. This presentation will report the state of discussion and highlight some aspects like uncertainty of low frequencies, influence of the chosen reference sound source spectra, or how to adjust current sound insulation requirements to the new quantities. The new concept of single-number description will appear as a separate standard ISO 16717 to allow a smooth transition from the existing ISO 717 system to the new one. |
