From the L.F.N. expert team to the Centre for Acoustic Measurement Technology: our path, our way of working, our commitment to standards.
An information website on low-frequency sound became a specialist centre; each step arose from a question that no one had been able to answer before.
Publication of the information website “Low-frequency sound of unknown origin”.
Founding of the L.F.N. expert team; systematic measurement concept for locating noise sources, assignments throughout Germany. The information website on low-frequency sound continues to be maintained.
Extension to measurements of known noise sources.
First articles are published, including Sound perception and Infrasound. All articles →
Founding of the Centre for Acoustic Measurement Technology; extension to noise forecasts and noise control engineering.
Contribution in the DIN/VDI standards committee NALS to the revision of DIN 45680.
Our engineers are represented in the following organisations and committees, among others. The memberships are held by individuals, not by the company.

The professional society for acoustics in the German-speaking countries. It organises conferences and technical committees and provides access to the current state of the art. Our engineers are registered there as individual members.
The part of DEGA that deals with noise control and noise effects, i.e. exactly the questions that arise in our assessments. Participation is through the same people as in DEGA.
The professional body representing engineers in the state, with a code of professional conduct and binding continuing education requirements. Individual engineers are registered there if they are members; the obligations also apply to them.
Personal contribution in the NALS standards committee, working group NA 001-01-02-11, to the revision of DIN 45680. Experts, not companies, are appointed to such a committee.
Our loan devices travel in reusable containers. The container comes back, is cleaned and goes out again instead of ending up as a cardboard box at the recycling centre. What this achieves in figures and where the really big lever lies is shown right below.
A measuring device travels in a cardboard box, padded and taped. Produced once, transported once, then disposed of, anew with every shipment.
The same container is used many times. Spread over its cycles: around 76 % less CO₂ and 94 % less waste per shipment.
Packaging, however, is not the big item: a single car journey weighs more than a hundred packages. For long-term measurements, we therefore send the device instead of an employee.
The lever lies in logistics, not in the office: remote read-out saves journeys, reusable packaging saves material, in that order.
The values in the illustration are orders of magnitude, not an audited calculation. We do not keep a certified carbon footprint; what we can substantiate is listed here:
What follows from this is not climate neutrality but a ranking: avoiding journeys matters more than optimising packaging, and both matter more than anything that happens in the office.
