dead air

Silence, meanwhile, is typically seen as a sign that one side is stumped—dead air is for losers.

Was it a mere thrill of the dead air, too slight to be heard, but quivering in every spiritual sense?

Just as they rode down by the first buildings a low whistle sounded on the heavy, dead air.

The walls are of concentric shells of copper and zinc with two of wood, between which is 'dead air,' an effective heat insulator.

And through the dead air came ever the low moaning of a distant sea, towards which my feet did bear me.
