Thanks to the experience acquired in underwater sound, no longer as a therapeutic application, but as repellent signals for Ifremer (Brest) as part of the PREDATOR project, we have considered a lasting solution to prevent fish coming down the river from entering. in the water supply channel of the hydroelectric power station.

This being identical to a concrete swimming pool, and with our expertise in this field of sound, it was enough to imagine creating a repulsive vibratory barrier at the entrance to the canal.
