Abstract

A device for absorbing acoustic energy from a fluid stream passing over a surface on which there is a multiplicity of fibers or filaments operatively attached to the surface and extending into the fluid stream, the device may be employed as a silencer in an automobile in which case the surface may be the interior surface of a conduit for association with an exhaust pipe. Automobile and marine mufflers or silencers employing the invention are effective in reducing or eliminating objectionable noise with only nominal back pressure.
