Beyond decibels

Trevor Cox in the New Scientist:

“One problem with decibel measurement is that it does not differentiate between “negative” and “positive” sounds. Take the sounds made by a fountain in a town square, happy children in a playground or the cheerful toot of the Manchester tram – any one of which might exceed permitted sound levels. Increasingly, researchers have been pressing for these positive sounds to be considered within urban design alongside more traditional noise-control approaches.”
