About us

Company

From the L.F.N. expert team to the Centre for Acoustic Measurement Technology: our path, our way of working, our commitment to standards.

Development

A question became a centre.

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.

  1. 2022

    Publication of the information website “Low-frequency sound of unknown origin”.

  2. 2023

    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.

  3. 2024Early

    Extension to measurements of known noise sources.

  4. 2024Mid

    First articles are published, including Sound perception and Infrasound. All articles →

  5. 2024Late

    Founding of the Centre for Acoustic Measurement Technology; extension to noise forecasts and noise control engineering.

  6. Since then

    Contribution in the DIN/VDI standards committee NALS to the revision of DIN 45680.

Memberships

Where we contribute.

Our engineers are represented in the following organisations and committees, among others. The memberships are held by individuals, not by the company.

German Acoustical Society (DEGA)

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.

DEGA Noise Working Group (ALD)

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.

Chamber of Engineers of Baden-Württemberg

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.

DIN – German Institute for Standardization

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.

Sustainability

We ship in reusable packaging.

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.

The cardboard box

A measuring device travels in a cardboard box, padded and taped. Produced once, transported once, then disposed of, anew with every shipment.

The reusable container

The same container is used many times. Spread over its cycles: around 76 % less CO₂ and 94 % less waste per shipment.

The journey

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.

What this means

The lever lies in logistics, not in the office: remote read-out saves journeys, reusable packaging saves material, in that order.

Context Where the figures come from

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:

  • Packaging. The savings of 94 % waste and 76 % CO₂ compared with single-use boxes come from a study by the Ökopol institute for the provider of the reusable system we use (provider's information). They apply to its system assumptions, not in general.
  • Journey. Calculated with the average value of the German Environment Agency for car traffic, applied to a round trip of 180 km. The actual value depends on vehicle, occupancy and route.
  • What is not included. Manufacture and disposal of the measuring devices, electricity during operation, server operation for remote read-out. The comparison shows the difference between two ways of working, not the overall footprint of an assignment.

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.
