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.

HESSI Modal Survey FEM Verification

Navcon Engineering was contracted to conduct the modal survey of the High Energy Solar Spectroscopic Imager (HESSI) spacecraft. The primary objective was to identify the damped natural frequencies, damping factors and mode shapes in the frequency band between 70 Hz. and 170 Hz.

SoundPLAN User Training Workshop
Noise Contour Examples from SoundPLAN training

The 2 day SoundPLAN Software Training  is intended for those engineers and technicians with little or no experience with SoundPLAN software and for users who have not had any formal SoundPLAN training.  Attendees will develop several  noise models and predict the noise from an industrial plant, local roads, a rail system, a race track, a constru

Zero-Position-Controller

The APS 0109 Zero-Position-Controller automatically controls the zero position of a vibration exciter irrespective of the payload. It is essential to employ a position controller of type APS 0109 especially when working with a vibration exciter without any integrated load compensation.

SoundPLAN - essential

SoundPLAN-essential is a single document application including all the basic information for noise control modeling and planning. It calculates noise from roads, railways or industrial noise sources. The computation can include one or multiple noise sources.

APS Power Amplifier 125 & 145

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.

Environmental Noise Training
Noise Measurement, Noise Modeling, Noise Assessment

The 2 day Environmental Noise Seminar is intended for engineers, technicians and hygienists working in the fields of environmental, community, and/or Industrial noise measurement, analysis and control.
