Noise monitoring of loud vehicles in four Dutch cities
conference paper
Noise from loud cars, motorcycles, mopeds, trikes and quads is commonplace in Dutch cities and is a major source of annoyance for residents. In order to assess the sources, causes and potential mitigation solutions, TNO performed a series of roadside noise monitoring campaigns in four major cities including vehicle identification. Data was acquired at 3 locations in each city for several days. Vehicle noise was separated from other noises, and attributed to the correct vehicles. The resulting analysis provided insight into the types of vehicles and driving conditions causing most noise. A set of characteristic driving conditions were derived, including high acceleration, engine revving, engine backfire, high engine speed and others. These conditions were also investigated in EU project LENS. Besides driving behaviour, vehicle modifications such as louder exhausts, removed dB-killers and mechanical or electronic engine modifications are common causes of high noise levels. Also an overview of suggested mitigation options and a future outlook is given, based on the findings of the analysis.
