Acoustic Diffusers
The Royal Albert Hall was opened in 1871 and at the time of the first acoustic tests an echo was identified. Although various methods were used to try and muffle the echo that reverberated around the auditorium the issue was not addressed properly until 1968 when 'mushroom' acoustic diffusers were installed. Originally there were 135 mushrooms but in 2001 these were reduced and reconfigured to 85 following more advanced acoustic testing.
