Arguments motivating remote experimenting are given. It follows from the presentation that basic experiments can be done automatically using “remote design”. The mo...

ADAPTIVE RESONANT MODE ACTIVE NOISE CONTROL Adam K. Smith, MS University of Pittsburgh, 2005 Low frequency sound waves propagating in a duct is ideally suited for active noise control (ANC) applications. Unlike passive treatments, ANC utilizes an acoustic actuator (loudspeaker) to cancel unwanted sound fields. There are two main control topologies when considering the active suppression of soun...

First-day spacecraft failures frequently occur as a result of the loads experienced during launch into orbit. These loads include structural vibrations transmitted at points of structural contact, and structural-acoustic vibrations created by the excitation of the payload fairing cavity. Structural control techniques, using piezoelectric actuators, have previously been studied as cost-effective...

Industrial machines like punching machines and presses can generate structure-borne impact noise, with noise levels exceeding the tresholds, imposed by legal regulations on noise emission. This paper presents an approach of non-collocated active structural acoustic control of transient noise, produced by a repetitive impact excitation. Although there is a significant difference in nature betwee...
