Resumen |
Primary noise control measures for existing prefabricated concrete formwork elements were identified by noise measurements. Welding of all contact points, fastening of heating pipes and installation of additional supporting structures were found to reduce the noise level at 1m distance from the formwork from 123dB(A) to 101dB(A). By changing the present design of the support structures and through attachment of sound screens the noise level would drop further to 89dB(A). |
