Impact sound acoustic performance using rubber ball: feedback from adivbois measurements on CLT floors

Résumé

Laboratory and field measurements of the acoustic performance of a CLT wood based floors were carried out within the scope of AdivBois acoustic technical commission with the objective of defining wood building constructions fulfilling defined requirements. French national regulation requires the use of the standardized tapping machine for impact sound performance measurements. Since the early 2000s, rubber ball impact source has been standardized in Japan and Korea to measure and evaluate the low frequency impact sound performance of floors; this excitation source is now part of international standards concerning acoustic measurement in laboratories and in-situ. Indeed, the impact sound level associated to this soft impact source is supposed to provide a better correlation with annoyance from jumping and/or running children. The paper reviews the measurements performed using the standard tapping machine and the rubber ball as impact source, on CLT based floors in a laboratory, as well as those on the CLT based building mockup. Results are presented and discussed. The necessity of measuring with both impact sources, or only with the tapping machine is examined.
