This marks our 28th year presenting the Hands-On Modal Testing & Analysis Training. Join the more than 1110 engineers and technicians who have tested a Navcon JimBeam and a fully race prepared Porsche.

SoundPLAN is an acoustic ray tracing program for noise propagation prediction written by the German acoustical consulting firm, SoundPLAN GmbH.

This module models the generation and propagation of low frequency sound in complex duct networks. The frequency range is limited to the plane wave region in the connecting pipes. It is based on linear acoustic theory and all elements, e.g., a complex muffler, are reduced to two-ports while terminations and sources are represented as one-ports.

dBSea has been developed by Marshall Day Acoustics as a powerful tool for the prediction of underwater noise in a variety of environments.

dBSea is ideal for the investigation of underwater acoustic problems involving single or multiple sources using solvers covering a wide frequency range.

The APS Dynamics Power Amplifiers are designed specifically to provide drive any vibration and modal exciter requiring 500 VA (Model 125) or 810 VA (Model 145). The output stage uses proven high reliability power operational amplifiers arranged to produce a balanced output.
