چکیده
Urban road traffic noise pollution causes various human health ailments. There is very limited research has been focused on different road traffic noise emission, which is significant to design environmental noise abatement measures. We studied different road traffic noise emission in roadside outdoor and indoor microenvironments, by field noise monitoring, traffic attribute study and meteorological data measurement (Jan-Dec, 2019) near a busiest G.S. road of Guwahati city and SoundPLAN 8.2 based FHWA TNM 2.5 noise modelling. The results depict that the measured noise level at outdoor and indoor were violated the WHO guidelines of 53 dB(A). The modelling study shows that with increasing the building floor level noise was increased up to 60 dB(A) at day and 56 dB(A) at night. The car was found as the leading noise producing vehicle in that study area, which contributed 66.9 dB (A) at day and 61.4 dB(A) at night. However, bike movement mostly contributed 250 Hz noise frequency of about 61.7 dB(A) and truck and bus contributed > 1 kHz noise frequency of > 50 dB(A). The results further showed that nearly 15%, 12%, 8% and 6% exposed people at outdoor could experience the highly sleep disturbances (HSD) due to truck, car, bike and MUV movements. Similarly, 4%, more than and around 3% exposed people at indoor could experience %HSD related to bike, car, MUV and truck movement. This finding could be useful for different noise abatement measures, including Noise Low Emission Zone (Noise LEZ) for controlling the urban noise pollution.
