Sound levels

I used ear plugs and Bose QC noise-cancelling headphones in the film Oppenheimer at a Vue cinema, and it was still too loud.

I downloaded a db app and tried it in my Y6 classroom when the children were working on a group activity a couple of days ago - the peak recorded was 98db - about the level of a petrol lawnmower.

Around 9-10 o’clock on the knob.

Rough end of Kent that.
