Melbourne Recital Centre, a venue for live music in Melbourne which was opened in 2009, has a 135 meters stage with optional 51 meters extension that can accommodate 45 to 65 musicians; however, the centre was not built to cancel out noise making it easy for people to hear to music from the inside.
Melbourne Recital Centre To eliminate noise from the nearby Southbank Boulevard cars and trams, it is surrounded by 250mm of concrete, mounted on 38 steel springs.
