Customer expierence

"To complete the required noise maps for the UK national noise mapping project, we carried out over 15 billion calculations. Lima gave us the capacity to carry out all of the calculations and effectively handle the data within the allocated six months"

 

Peter Hepworth

Director Hepworth Acoustics UK

"We have now dealt with Stapelfeldt Ing. mbH of Dortmund for over twelve years. The quality of service we receive is excellent with prompt responses to queries and periodic software upgrades and enhancements as required/available"

 

Andrew Jellyman

Principal Technical Officer Acoustics (Birmingham City Council)

"Our organization routinely uses LimA as our in-house modeling package. We are in regular contact with Stapelfeldt Ingenieurgesellschaft mbH for support and have been very satisfied with the level of service and quality of LimA software"

Why they choose us


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 modelling, to traffic noise predictions in large cities, such as Madrid or Hong Kong.


 

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

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).
