Noise Annoyance Due To Urban Road Traffic with Powered-Two-Wheelers: Quiet Periods, Order and Number of Vehicles
This paper aims to assess the influence of different acoustical characteristics of urban road traffic including powered-two-wheelers on noise annoyance. The factors studied under laboratory conditions are the number and order of the different urban road traffic noise events, and the
position and duration of quiet periods between noise events as well as their cumulative duration. Several listening experiments were carried out. The urban road traffic noise sequences were presented to a panel of participants for short-term noise annoyance assessment.
First, the presence of quiet periods was found to reduce noise annoyance but there is no effect of the duration and the position of quiet periods on noise annoyance due to urban road traffic noise. The order of the noise events within the sequence was not found to impact noise annoyance. It seems that annoyance due to urban road traffic noise is determined by the presence of a particularly annoying noise event. The findings of this study will contribute to the understanding of the influence of the studied acoustical factors on noise annoyance due to urban road traffic. Furthermore, the gained knowledge may be used to develop models for the assessment of noise annoyance due to urban road traffic.
