The INSUL software is developed by Marshall Day Acoustics, Auckland  - New Zealand. Navcon is the INSUL distributor for USA, Canada and Mexico.

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.

SIDLAB Measurement

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

This marks our 29th year presenting the Hands-On Modal Testing & Analysis Training. Join the more than 1160 engineers and technicians who have tested a Navcon JimBeam and a fully race prepared Porsche.

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
