US Patent:

7011180, Mar 14, 2006

Filed:

Apr 9, 2003

Appl. No.:

10/410429

Inventors:

James E. Gallagher - Kingwood TX, US
Michael P. Saunders - Kingwood TX, US

Assignee:

Savant Measurement Corporation - Kingwood TX

International Classification:

F01N 7/02
F01N 1/10
F01N 1/12

US Classification:

181232, 181252, 181256, 181279, 181280

Abstract:

A method is employed to attenuate ultrasonic noise propagating in a flow stream of a fluid flow system. In particular, the method attenuates the noise propagating between a noise source and a reference point in the flow stream (wherein the reference point and the noise source are positioned in the flow stream in direct acoustic line of sight relation). The method includes positioning an absorbent element in the flow stream between the noise source and the reference point. Then, the ultrasonic noise is directed past vicinity of the absorbent element such that indirect ultrasonic noise is absorbed by the absorbent element. Preferably, the method also includes deflecting the ultrasonic noise to convert direct noise to indirect noise prior to directing the ultrasonic noise past the vicinity of the absorbent material in the flow stream. Such a method may be employed to attenuate ultrasonic noise by up to about 20 dB to 45 dB.
