Sound Maps Can Be Used To Predict Changes In Bird Song Due To Noise Pollution

There is growing evidence, from multiple species on multiple continents, that anthropogenic noise strongly influences the characteristics of songs performed by urban birds. However, the studies that have uncovered these relationships have generally relied on ambient noise recordings collected at the same time as male song recordings, and by the same researchers. A recent study describes how, for the first time, a team of scientists has attempted to correlate variations in song parameters with noise levels generated by sound maps--a type of map often produced by urban planners in order to assess which areas of a city are loudest.read more
