Noise Baffle For Drain Pipes
US Patent:
5159789, Nov 3, 1992
Filed:
May 14, 1990
Appl. No.:
7/523019
Inventors:
Randy M. Haapanen - Durham CA
International Classification:
E04D 1308
US Classification:
52 16
Abstract:
A noise baffle for reducing noise in rain gutter systems is provided. A screen or other perforated or fibrous surface is secured beneath a vertical downspout section and above the surface of an angled downspout section for reducing the noise caused by water striking the surface of angled downspouts. The screen eliminates or substantially reduces the noise by breaking the fall of the water falling in the vertical downspout section and dispersing the stream into tiny droplets which do not strike the bottom of the angled downspout section with sufficient force to create noise.
