Matej Repel, director of Avescentrum Senne enjoys the sound of nearby birds as he sits inside a huge birdsong-amplifier that was recently installed for visitors, on April 24, 2025 near Michalovce, Slovakia. The 3 meter tall and 5 meter deep wooden amplifier is a unique installation in the country and was inspired by a similar amplifier based on a student's project in Estonia.
