Schematic of Small Muffler with two chambers and perforated openings between the chambers.

The APS Dynamics series of air bearing long stroke vibration exciters provide excellent properties for low frequency excitation of accelerometers and other low frequency instruments and sensors. Some models have a horizontal air bearing table coupled to the driver unit that allows high payloads up to 23 kg e.g.

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.

Noise has a multitude of effects on our environment and society.  As part of modern civilizations standards and legal ruling have been developed and are continuously updated to set parameters for equipment limits, city, state or federal requirements.  These standards and legal rulings regulate what is consider audible, acceptable, allowable or s

The APS Dynamics Model 300 Portable Shaker is a self contained shaker and amplifier in an aluminum carrying case. For operation, the unit separates into two sections - the Amplifier Section and the Shaker Section
