Environmental noise measurements (e.g., traffic noise) are of great importance for understanding and mitigating the effects of noise pollution in society. Accurate measurements provide valuable insights into the extent of noise exposure that the population experiences.
By measuring traffic noise levels, we can identify particularly affected areas and determine whether they exceed recommended noise limits. This data assists urban planners and decision-makers in making informed decisions when designing new roads, implementing noise barriers, or determining land use. Furthermore, measurements contribute to assessing the validity of noise models and reduction measures, as well as evaluating the success of noise reduction policies.
Additionally, noise measurements aid in understanding patterns such as maximum noise periods, noisy vehicle categories, and areas with higher vulnerability due to noise-related health impacts. In the long term, measurements enable society to work towards a quieter and healthier acoustic environment, improving overall well-being and quality of life.
The Institute of Environmental Science uses noise measurements to compare with the results from noise calculations for evaluating the validity and uncertainty of model calculations, such as Khan et al. (2023). Noise measurements using portable sensors are also conducted to study the temporal and spatial noise patterns at traffic hotspots. The institute possesses high-quality equipment for portable noise measurements.
