Precision air convey acoustical 90.* 90-degree radius elbow Elbow ignorant, blundering constable. [Br. Lit.: Measure for Measure] See : Stupidity engineered as a sound attenuation Loss of signal power in a transmission. Attenuation The reduction in level of a transmitted quantity as a function of a parameter, usually distance. It is applied mainly to acoustic or electromagnetic waves and is expressed as the ratio of power densities. device * Reduces sound pressure levels created during the cutting and evacuating of film, foil and paper as well as other material * Can be custom engineered or retrofitted on existing systems Visit www.precisionairconvey.com, e-mail get-facts@airconvey.com or call 302-999-8000 for more information.
