Structural Dynamic Modification
APS Dynamics Inc. Shaker & Amplifiers

The Company began operations in Anaheim, California in 1971 as Acoustic Power Systems, Inc. Initially, the Company specialized in the development of high power acoustic generators. Subsequently, the company focused on the development of electro-dynamic shakers and power amplifiers. The Company's name was changed in 1989 to APS Dynamics, Inc.

SIDLAB Measurement

SIDLAB Measurement

This is a post-processing module for measurement data. It handles two types of measurements: 

IRIS 3D Acoustic Impulse Response
IRIS Software Hedgehog display

IRIS is a room acoustics measurement system developed by Marshall Day Acoustics in New Zealand. It was released at the beginning of 2014 as a fully integrated hardware and software system for making 3D impulse response measurements.

SoundPLAN User Training
Noise Contour Examples from SoundPLAN training

The 2 day SoundPLANnoise software training is intended for those engineers and technicians who are responsible for developing indoor and outdoor acoustical models used for noise planning, noise impact assessments, noise mitigation, etc. SoundPLAN is used extensively throughout the training, however, the training will be of interest to anyone wor

ELECTRO-SEIS Long Stroke Exciter - Ball Bearing

The ELECTRO-SEIS® is a force generator specifically designed to be used alone or in arrays for studying dynamic response characteristics of structures such as automobiles, aircraft, bridges, floors, missiles, piping systems, spacecraft, towers, etc.

SIDLAB Flow
SIDLAB Double Plug Muffler Flow Model Schematic

SIDLAB Flow is a very quick 1D tool to calculate the pressure drop introduced by the designed muffler system. It calculates the flow distribution and pressure drop inside the network using a two-port formulation, and feeds the results into the acoustic calculation in SIDLAB Acoustics.

dBSea - Underwater Noise Prediction
dBSea - Underwater Propagation

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.

SIDLAB Acoustics
SIDLAB Double Plug Muffler Model Schematic

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.
