A cylindrical micro-perforated panel (MPP) can be used to absorb the sound of a flow system in a circular duct of a vacuum cleaner. A cascaded cylindrical MPP is a special class type where two cylindrical MPPs are arranged in a series to improve soun

Noise produced by a vacuum cleaner is highly unpleasant and may cause hearing damage if exposed to it for a long period. Thus, this study aims to identify the noise source of household vacuum cleaner and provide a solution to reduce its noise level.

An engine mounting system is the primary vibration isolator of the engine from the chassis. The frequency-dependent stiffness and loss factor present a more accurate representation of a rubber mount as opposed to the frequency-independent damping mod
