DMR (Dansk Miljørådgivning A/S) is one of Denmark's larger environmental consultancies. Their bat team handles acoustic surveys for building, biogas, and infrastructure projects across Sjælland and Jutland.

In summer 2025 they tested BioSonic on a single project. By spring 2026 the whole team had switched.

Why they switched

Before: BatSound

Files on a shared drive. Building sonograms one by one. Getting a second opinion meant emailing files back and forth.

After: BioSonic

Everything in one browser tab. Click a file, see the spectrogram, see the AI suggestion, agree or correct, move on.

The team also wanted features BatSound didn't offer: detection tables per species, downloadable graphs for reports, and a way to see flight patterns between detectors at a site.

The first test

DMR met BioSonic on 13 June 2025. Josef ran a demo for Lars and his team. Lars was honest: he needed a strong economic case before his boss would say yes.

So they started small. DMR's next project was a building survey covering 15 buildings and 25 hectares, expected to generate around 5 GB of recordings. One test, no commitment.

The result

Noise filtering

Noise files filtered out automatically

One place

“It's seldom wrong”

“It's been helping me a lot. It's been saving me at least 10 hours for this project, and actually probably much more, because with BatSound I almost gave up trying to find the files and making new sonograms. With BioSonic I have everything in one place. I can click through it easily, find my file, find my sonogram, and look through those that I might be in doubt of. It's seldom wrong.

Lars Michael Nielsen, biologist, DMR

“It's saving my time, it's much more precise, it's actually fun using it. Sometimes I just look at it because it's interesting, and I learn things as well. I love that you have several species in one sonogram. It's just a great experience.”

Rolling out to the team

After the first project, the question changed from "should we?" to "when does the rest of the team start?"

Through autumn and winter 2025, BioSonic shipped the features DMR asked for: detection tables, downloadable graphs, weather data overlays, and better visualisation of activity patterns between detectors.

On 25 March 2026, the full bat team was onboarded in a single 56-minute training session. Seven users now share a DMR workspace inside BioSonic.

Why the team stayed

Speed

10+ hours saved on the first project alone. That time goes back into writing better reports.

Accuracy

"Seldom wrong" is a high bar for a Danish biologist. Strong noise filtering and reliable species classification means less manual review.

One workflow

Files, sonograms, species correction, report graphs. All in one browser tab instead of BatSound, a shared drive, and Excel.

What's next

DMR feeds feature requests into BioSonic. BioSonic ships them. Both teams stay in regular contact through a shared Teams channel.

If your consultancy uses BatSound, Kaleidoscope, or another desktop tool, the path DMR took is straightforward: start with one project, measure the time, decide from there.
