Climate action
As noted under SDG 11, Sustainable cities and communities the greater reliance on renewable sources of energy as an alternative to carbon-based fuels is not without unwanted consequences, with low frequency noise being amongst them.
However, there is also a positive role for acoustic measurement in climate studies. Research is showing that measurements of infrasound are important in understanding the physical characteristics of the stratosphere. This understanding can be used to enhance weather forecasting and climate change models.
IEC TC 29 is currently active in developing standards for calibration methods at infrasound frequencies, to improve the quality of data obtained from microphones and other acoustic sensors in atmospheric acoustics applications.
