Impact Sound Transmission Field Data for Concrete and Wood Joist Floors

A recent paper describes methods of evaluating the resistance of floors in buildings to impact sound such as footsteps [1]. The field measurements were combined, with laboratory results [2] previously collected on surface additions to a 4-in. reinforced concrete slab. As both papers are concerned with test methods rather than with test results for specific floors, the individual floor constructions were not described. Further details of the floors considered in Reference 1 are given in this Note; the constructions studied in Reference 2 have already been described [3].Une publication r\ue9cente rend compte des m\ue9thodes d'\ue9valuation de la r\ue9sistance au bruit d'impact tel que les pas [1] dans les \ue9difices. Les mesures effectu\ue9es sur le terrain ont \ue9t\ue9 combin\ue9es \ue0 deux r\ue9sultats de laboratoire [2] d\ue9j\ue0 compil\ue9s sur des mat\ue9riaux ajout\ue9s \ue0 la surface d'une dalle de b\ue9ton arm\ue9 de 4 pouces. Les deux documents traitent des m\ue9thodes d'essai plut\uf4t que des r\ue9sultats d'essai sur des planchers sp\ue9cifiques et ne d\ue9crivent donc pas la construction de chacun des planchers. Le pr\ue9sent document contient des d\ue9tails sur les planchers dont il est question dans la r\ue9f\ue9rence 1. Les constructions \ue9tudi\ue9es dans la r\ue9f\ue9rence 2 ont d\ue9j\ue0 \ue9t\ue9 d\ue9crites [3].Peer reviewed: NoNRC publication: Ye
