Abstract
The present invention provides for noise reduction during operation of a portable blower by reducing the noise or acoustic energy escaping from the inlet of the blower housing. The noise reduction is achieved in one respect by placing sound absorbing material in a plenum attached to the inlet opening of the blower housing. Other features of the preferred plenum include louvered openings and angled engagement members to draw the plenum tightly against the blower housing.
