Operator Cab Interior Noise Reduction Material Selection Test Method 891946
The noise insulation of operator cabs for agricultural and construction equipment has become increasingly important in the last few years. Cabs that are noise insulated promote two-way communication and operator comfort, both being desired by the agricultural and construction equipment consumers.
This paper presents a discussion concerning a method which quiets the interior of a cab using noise control materials effectively, efficiently, and in a cost effective manner.
A method of determining the noise paths into the operator cab, the window technique, will be examined. Selection of appropriate absorption, damping, barrier materials, and the effective placement of these materials to achieve reduced noise levels will be discussed.
