Abstract
The present invention relates to a noise attenuating window comprised of two panes of glass separated by a spacer tube. The spacer tube contains T-shaped acoustic resonator capable of targeting a single mode or multiple-mode to be attenuated.
Claims5
A noise attenuating window, comprising a spacer frame;
- two glass panes attached to opposite sides of the spacer frame;
- a T-shaped acoustic resonator array embedded into the spacer frame;
- and
- an outer frame adapted to hold the spacer frame and the two glass panes,
- wherein the T-shaped acoustic resonator array includes a plurality of T-shaped resonators, and the T-shaped acoustic resonators in the array have more than one working resonance frequencies, and
- wherein each of the T-shaped resonators are separated by a pair of end caps, and at least two of the T-shaped resonators, with different working resonance frequencies, share the same end cap.
