Planet earth is a particularly noisy place. From the hustle and bustle of people, traffic clogging the streets and new construction in our cites to the song of the nightingale and the sounds of water cascading down a waterfall in the countryside, we are subject to all manner of sounds, often without giving them a second thought. From the downright painful to the serene, sound impacts on the health and wellbeing of us all, never mind the impacts it may have on the other animals we share this planet with. In this edition, we seek out tranquillity and how to measure it, explore the balancing act of noise pollution mitigation in construction and learn how to safely deter bats from flying into danger.
