Soundscapes, SPL and Standards
Was talking with a workmate earlier about environment sounds and why urban planners don’t spend more time designing our cities soundscapes. Perhaps stricter laws need to be enforced for SPL (sound pressure level) outdoors and not just in the workplace. A quick look at the Canadian laws regarding SPL: Levels of Sound – Canada Occupational Health and Safety Regulations, Part VII.
And from the Canadian Centre for Occupational Health and Safety: “Sound is what we hear. Noise is unwanted sound. The difference between sound and noise depends upon the listener and the circumstances.” Great quote!!
If you have an interest in the affects of SPL in the workplace, education establishments and cities check out Julian Treasure’s TED talk below on encouraging designers to focus more on SOOOUND.
