    Our Goal

    is to provide you with dedicated software and services to take on the full-range of environmental impact analysis with high efficiency - producing results that will gain the respect and trust of your customers

Why they choose us

Proven Performance

Proven Performance For the past 30 years, our products have proven their performance across a variety of projects, ranging from small-scale applications, such as industrial plant emission modeling, to traffic noise predictions in large cities, such as Madrid or Hong Kong.

Dedicated Support

Dedicated Support Your challenge is our challenge. Our customers benefit from an open-door policy and can rely on our help when accepting projects beyond the beaten path. Our experience in consulting keeps us in touch with the reality of environmental emission modelling and translates into continuous improvement and innovation for our products.

Custom Solutions

Custom Solutions We believe in lean processes that avoid repeating tasks and redundant work. Our software products are designed to enable clients to tailor them to specific processes and automate their workflows. Any function of our products can be integrated in batch-processes and our extensive library of macros provides for individual solutions to complex problems.


Powerful LimA has been independently proven to be the fastest noise propagation software on the market. In the comparison study by Hepworth Acoustics, LimA was compared to three other noise modelling software solutions and was found to calculate almost twice as fast as the next best competitor


Scalable We offer additional computation resources with flexible plans so that our customers can upgrade their computational capacity when the need arises. This option enables our customers to tackle large-scale projects, for example computing the world's largest noise map in the UK


Up-to-date Requirements to noise and emission modelling methods change constantly. To ensure that our software and customers are always up-to-date, we actively participate and contribute in all major national and international standard committees such as ISO 17534 (software noise calculation) and DIN 45682 (noise mapping).
