Sound is a major distraction, particularly in a commercial building. The staff does not want to listen outside their workplace to the crescendo of heavy traffic. Even if you are at home, you would not like the sound of jets roaring overhead late in the night.
With an additional layer of insulation, our green spaces can trap up to thirty percent of emissions from ambient noise. You can get on with the job, away from distractions, or rest in your bed at night more comfortably.
