49th Scandinavian Symposium on Physical Acoustics

1–4 February 2026

Post-symposium information

The 49th Scandinavian Symposium on Physical Acoustics was successfully carried out with 59 participants. Over the course of three days, we attended 31 full presentations spanning many topics such as underwater acoustics, ultrasound imaging, acoustic non-destructive testing, transducer technology, and geoacoustics. Along with the regular presentations, we also attended student presentation session for Master students from both the University of Bergen and the University of Oslo, and a special session for retiring professor Per Lunde.

The organisers would like to thank the participants and especially the presenters for making the symposium a success. Finally, we would like to give Erlend Magnus Viggen a heartfelt thanks for his smooth organization of this event for the past years!

We hope to see everyone back at Geilo for the 50th symposium, which is planned for 31 January – 3 February 2027.

Proceedings

Everyone who held a presentation at the symposium is invited to make a submission to the Proceedings of the 49th Scandinavian Symposium on Physical Acoustics. We allow two types of submissions:

  • Full articles, which should give a full account of the work you presented. Article submissions have no page limit.
  • Extended abstracts, which should give a brief summary of the work you presented. Extended abstracts are limited to four pages.

Submissions must be written using the provided LaTeX or Word templates. Please contact us at SSPAGeilo@gmail.com if you have any questions about the proceedings or issues with these templates.

To submit your article, please send it as a .pdf file to SSPAGeilo@gmail.com. The submission deadline is Friday, 15 May 2026.

Pre-symposium information

While the 49th Scandinavian Symposium on Physical Acoustics has now been successfully carried out, we keep the original pre-symposium information below for posterity.

The Norwegian Physical Society is happy to announce the 49th symposium in the series, which will be held at Geilo, Norway. We encourage you to participate, and to distribute this invitation to others who may be interested in joining this symposium!

About the symposium

As always, the theme will be physical acoustics, with an emphasis on ultrasound, marine acoustics, nonlinear acoustics, and sound propagation in general, with applications in technology, medicine, fisheries, environmental monitoring, and defense.

The main purpose of these symposia is to strengthen contacts and exchange information between acoustics groups in Scandinavia. The symposium is held in English, and non-Scandinavian participants are very welcome.

The symposium has a quite informal tone, and is designed to facilitate getting to know colleagues, both during the sessions and during scheduled social activities indoors and outdoors. Geilo is one of the main sites for downhill skiing in Norway and has excellent tracks for cross-country skiing as well.

Program

We will follow the same schedule as usual. The symposium opens on Sunday evening after dinner. On Monday and Tuesday, there are morning and afternoon sessions with a long break in between for networking, skiing, and lunch. On Wednesday, there is a morning session before the symposium closes in time for the trains to Oslo and Bergen.

We invite and encourage our participants to contribute 15-minute talks, though doing so is not mandatory. Furthermore, fresh master and PhD students are invited to give a 3-minute presentation of their project in a special session. Typically, the symposium attracts around 60 participants, holding about 30 talks throughout the five sessions.

Registration

There is no registration fee.

Participants are kindly requested to register as soon as possible, and no later than 17 December. Please use the registration form to indicate your time of arrival and departure, whether you require a single or double room, any accompanying persons, and the title of your talk if you intend to hold one. Rooms are automatically booked for all registered participants, and participants pay directly to the hotel at the end of their stay. If you would like to extend your stay outside the symposium period, it can be arranged by contacting the hotel directly.

Proceedings

After the symposium has been carried out, presenters are invited to submit full articles or extended abstracts for the symposium’s Open Access proceedings. Note that such submissions are voluntary, and are not required for presenting at the symposium. The proceedings submission deadline is usually set to around Easter.

Travel

From the southern half of Norway, the most convenient options to get to and from Geilo are driving a car or taking the train.

Geilo is roughly in the middle of the Bergen Railway between Oslo and Bergen, and the train journey from either end takes about 3–4 hours. Early estimates for the most relevant train times are:

  • Sunday, Oslo–Geilo: 12:03–15:44 or 14:25–17:58
  • Sunday, Bergen–Geilo: 11:49–15:00 or 15:37–18:45
  • Wednesday, Geilo–Oslo: 11:12–15:05 or 15:04–19:05
  • Wednesday, Geilo–Bergen: 11:56–15:00 or 15:49–19:10

More train options, up-to-date train times, and train tickets are available at entur.no or in the Entur app.

If you are joining us from further away, the two best options are to fly either to Oslo or to Bergen and then take the train from there to Geilo:

  • From Oslo Airport, Gardermoen, you can take the Airport Express Train (frequent departures, but more expensive) or a regular train (cheaper, but less frequent departures) to Oslo Central Station and take the train to Geilo from there.
  • From Bergen Airport, Flesland, you can take the Bergen Light Rail to the Nonneseter stop. This is right next to Bergen Central Station, where you can take the train to Geilo.
