Insul is a quick and accurate tool for predicting the sound insulation in walls, floors and ceilings.

With extensive drop down menus to select materials, and simple choices for construction details you can quickly evaluate different constructions. INSUL shows a picture of your construction and a graph of the 1/3 octave TLs.

 


 

INSUL can be used to quickly evaluate new materials and systems, or to investigate the effects of changes to existing designs. It models materials using well known elastic plate theory including allowances for thick panel effects as published by Ljunggren, Rindell and others. More complex partitions are modelled using work by Sharp, Cremer and others.

 


INSUL takes account of finite size effects which are very important when predicting small samples such as windows and also for normal elements at low frequencies.

Like any prediction tool INSUL is not a substitute for measurement. However, comparisons with test data indicate that INSUL reliably predicts STC values to within 3dB for most constructions.

INSUL will greatly enhance the ability of acoustic consultants and product manufacturers to quickly and confidently specify constructions in order to achieve a desired airborne sound insulation.


It can predict the effect of installing an acoustic blanket in the stud cavity. It has evolved over several versions into a very easy to use tool that takes advantage of the Windows environment, and has been refined by continued comparison with laboratory tests to provide acceptable accuracy for a wide range of constructions.

Test data can be entered to permit easy comparison with predictions and constructions can be saved for later recall.
