Thank you for supplying us with your SOUNDEX® acoustic enclosure, we have been using it constantly for two months in the main station concourse area. The main station has an enclosed roof which when we started breaking the existing floor we were told to stop because of safety issues, the station staff could not hear if there were any evacuation announcements. Once we installed your SOUNDEX® E4/2 acoustic enclosure the decibels were reduced dramatically. We monitored the announcements and they were able to hear fine and speaking to the guys on site they were happy to work within the acoustic enclosure. The next phase of our works will be continuing in the same way so we will be using the enclosure again.
