Project Information
The in clusion of a new bowling alley operated by Hollywood Bowl at the new Derby intu Shopping Centre required careful acoustic planning.

Formed within the existing level 3 car park above the second level retail units, high levels of impact and airborne noise from both the pinsetters, and the dropping and rolling of balls on the lanes and run-up area, had to be mitigated.

A target of NR35 in the retail units below was set. To achieve this target the steelwork frame supporting the pinsetters was suppo rted on a number of Sylodyn NF isolatio n pads at 37.5mm thickness, providi ng a natural frequency < 8Hz, compl ete with TVS Resilient Washers to isolate the anchor bolts.

Similar ly a RESi FFS concrete floating floor of 100 mm depth, with a minimum void of 100mm, supported on TVS 505008 isolators with a natural frequency of 8.5Hz, provided suffic ient isolation to support the bowling lane and run-up areas.
