Four buskers on Grafton Street, Dublin with their decibel levels

Further to all the Busking Noise Hullaballoo, some science is needed. I got interested in this one day during the summer when lots of buskers were out out of Grafton Street. I downloaded an app to measure decibels and which also allows you to take a photo of the source at the same time. The results were interesting.
The loudest busker I recorded was 93 decibels. That is almost four times louder than the average background street noise of about 74 decibels (The decibel scale is logarithmic). Most “miked-up” buskers came in at 90-92 decibels, though I once recorded one at 97 decibels! Non-boosted performers come in at 75-83 decibels. That is over five times times quieter than their electric cousins…
