I visited a nearly privately owned and run Theater & Opera House, the second biggest after the Paris Festival Hall – in Baden Baden.

Being curious about the ideas and implementation actions regarding all improvements on the sound quality I found some details:

This is the entrance hall, the former main train station – where tickets are sold.

The side walls are made and painted with an extra mixture of not reflecting too much waves.

Side corners are equipped with a special glass having some extra inlays on the backside.

The roof side is equipped with dampening buffers.

The stage.

and backstage.
