Dr Sarah Goldingay’s mission, she assured her listeners at the start of this wide-ranging Sabbath morning half-hour (19 February), was to reimagine, re-evaluate or even re-sanctify noise; to listen out, as she put it, “to divine noise in and amongst the din”. If this realised a certain amount of jargon-heavy academic chat about “sonic situations”, it also produced some intriguing insights from the percussionist Dame Evelyn Glennie, profoundly deaf from the age of 12, about what noise “felt like” when you could not technically hear it, and the visceral quality that lay at its core.

It was no surprise to find that the medical profession had begun to appreciate the healing properties of sound.
