Grinder – Stairwell – Recording gear
Had a chance to record an occluded mechanical grinder throughout our buildings twelve stories. One of the most interesting sounds was in the stairwell, walking up and down each floor was like adjusting the wet / dry mix.
Over 45 minutes of audio was edited using different mics and perspectives. How to turn an awful sound into library 101. Here are some samples of the recording to download.
Mono 24bit / 96KHz
Rode NT4, NTG3
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.
This sound was captured from a UFO take off from the Hôtel de la Montagne terrace, in Montréal. Standing around 70 meters away, the sound pressure level must’ve topped 130 dB! Captured with a Zoom H2.
Recorded by Alexandre Saba in February 2012.
