BB93 Performance Standard 
Within the current BB93 government guideline Cheshire Soundproofing can design and propose the supply and installation of hi impact acoustic panels designed for school sports halls, gymnasiums, sporting venues and five- a -side football pitches. 
A range of Class A-C acoustic absorption products are available for external and internal use. These specialist panels are impact resistant therefore can be installed at low level areas allowing for hits, knocks and disturbance. 
Within the BB93 guidelines most environments have an acoustic performance standard to adhere to. Using these guidelines Acoustico UK will calculate the existing reverberation time (Rt) in any area. By then proposing a coverage of acoustic products the aim is to achieve the performance standard by improving the Rt time resulting in better sound absorption and reverberation control. The performance standards vary if the area is within a new build or a existing building undergoing an acoustic refurbishment.
