We generate a huge amount of noise, whether it’s our rumbling roads, pumping parties, or talkative tourists. And the topic of noise also generates a lot of questions from our listeners. In this episode we explore three of them, with the help of acoustic scientist Kurt Fristrup and neuropsychologist Catherine Loveday. Listener Dominique finds it hard to experience even one minute of a natural soundscape without some intrusion of human-made noise. He wonders how noise pollution is affecting both the natural world and us humans. We discuss just how noisy our modern world is, and visit a National Park in California to hear how they’re encouraging more peace and quiet there. Meanwhile Michelle, having witnessed her husband wince in pain at the sound of squeaking takeaway boxes, asks why certain noises are particularly unpleasant or even painful to some people. And finally, Jennifer has a sonic mystery for us to solve: why does the time of day make such a difference to the distant noises reaching her remote home? With contributions from Professor Catherine Loveday, Dr Kurt Fristrup and Mia Monroe.
