INDOOR TRAFFIC NOISE IN A HIGH-RISE CITY

The investigation reported in this paper was initiated to determine the relationship, if any, of the indoor noise level due to traffic in a high-rise city, Hong Kong, with the outdoor level. Eight concrete buildings within the high-rise city were chosen for their similar construction and interior decoration, and noise measurements were made in rooms one or two floors above street level and in rooms with windows facing the road. Two Bruel and Kjaer sound level meters, with one inch microphones and Nagra tape recorders were used. The results of simultaneous measurements of outdoor and indoor noise levels are discussed. Best fit curves were found to fall within a band having a width of about 2.5 db(a), and further investigation is recommended to isolate factors such as variations due to different building construction, interior furnishings, etc. /TRRL/
