THE PERFORMANCE OF SOUND ABSORPTIVE, REFLECTIVE, AND T-PROFILE NOISE BARRIERS IN TORONTO

A 4 M (13 ft) high highway noise barrier in Toronto was tested first with an absorptive side, second with a reflective side, and finally with a horizontal cap 75 cm (30 in) wide mounted on its top to create a t-profile. Sound measurements in the residential community behind the barrier showed the t-profile barrier to produce a noise reduction 1-1.5 db(a) greater than the same barrier without the cap. There was no statistically significant difference between the noise reductions produced by the absorptive and the reflective configurations. (Author/TRRL)
