A Swiss city has banned silent disco events due to concerns about noise.

Locals in Lausanne on the shore of Lake Geneva has lodged noise complaints over rooftop events in the city's Flon neighbourhood and the Place de l'Europe.

The organiser of these events, Oliver Meylan, had applied to stage a series of silent discos on bistro rooftop terraces in the Flon neighbourhood on June 12 and September 4 running until 5am on both occasions.

Despite being backed by the owner of the bistros and the neighbouring municipality of Pully where similar events have been - the application was denied.

Florence Nicollier, the head of the city's business regulation department, told 20 minutes: "Since 2014 numerous complaints from neighbours have been lodged

"They involve noise problems caused by musical events and other activities taking place on terraces of establishments in the Flon neighbourhood and the Place de l’Europe, in particular those on rooftops

"During silent discos, the noise caused by the clientele is not negligible."

There was concern that people attending silent discos often sing along.

Mr Meylan replied to the city's decision: "Given our experience in the neighbouring municipality of Pully, we should have been able to at least try a test in the centre of Lausanne and take stock afterward, but no.
