by andrea lawson we live surrounded by sounds, but unfortunately not all of them pleasant.
michael schutz, associate professor of music cognition and percussion, is working on how to improve some of those sounds, specifically those in hospitals.
“like most musicians, i’m really interested in sound, and i spend a lot of time thinking about sounds and what makes them good and bad,” he told cbc radio’s
quirks and quarks.
good sounds, like the ones we use in music, are often very complex. even a single note has a lot going on. meanwhile, simple sounds, like the ones used in medical devices, are often very annoying, he said.
in fact, those beeping devices are so annoying, schutz said a nurse once described her workplace as a “beeping hellscape.”
“annoying is fine for some alarms, like a fire alarm, because the purpose of that alarm is to make you want to leave. so there the more annoying, the more effective it is,” he said.
“these medical device alarms have a very different purpose, because here, their goal isn’t to alarm and make medical doctors and patients want to leave, but to inform.”
beyond the annoyance they cause, schutz said these bad medical device sounds lead to alarm fatigue for medical professionals and interrupts patients’ sleep, which can extend recovery time. there is even data from the fda that found problems with these alarms have led to over 500 patient deaths.
