The sound of rain falling all around you, an arrow or bullet whizzing by your head, or the panning
effect of a jumbo jet flying over, these are the kind of head - spinning, duck - for - cover audio experiences that create a more convincing audio experience.
A 2010 Stanford University study found that these domes act like pressure cookers, exacerbating pollution's harmful health
effects, and may already be responsible for up to 1,000 excess deaths across the country, the equivalent
of two
jumbo jet crashes every single year.
