We were asked by the Canal and River Trust to treat their new observation chamber at the Diglis Fish Pass. Being a concrete construction, underground chamber with a metal staircase the acoustics were terrible. We measured the reverberation time at 3.97s Tmf however at the low end 63Hz we measured 11.96s. After treatment by Woolly Shepherd we brought the time down to 0.76s Tmf. Unfortunately, due to budget restrictions, there is still an issue with the low end reverberation however the overall acoustics are hugely improved as you can hear in the video.
