King Ethelbert School in Kent
Sports hall acoustics are typically reverberant due to a combination of large areas of hard block walls, corrugated steel ceilings and wood floors. To control a sports halls acoustics a large amount of acoustically absorptive material has to be applied around the hall. Clearly a spray-on material has a distinct advantage over acoustic panels in this situation.
Oscar Acoustics are specialists at controlling sports hall acoustics. Each project is taken as a completely separate case. Prior to installation, acoustic measurements are taken and with purpose designed software computers create a sports hall acoustic model. This enables Oscar to calculate which areas require treatment to achieve the desired results. The sheer size of the project in the photographs, determined that acoustic treatment not only had to be applied to the ceiling in certain areas, but due to the height of the ceiling, the walls also needed treatment to prevent sound polarisation.
Two very different products were used to control this sports halls acoustics. SonaSpray K-13 acoustic decorative finish in white was applied to the centre area of the corrugated steel ceiling, SonaSpray
K-13 in green was applied to the upper section of the steel clad walls, and SoundBlox were used at low level.
SoundBlox building acoustics blocks are the perfect product for controlling sports hall acoustics at low frequency, they absorb both direct and reflected sound by using Helmholtz resonator principles. The selection of blocks along with the use of absorptive cavity fillers for high frequency attenuation enables Oscar to adjust absorption characteristics to suit the requirement. They are also designed to be laid along with standard masonry blocks and can create complete walls or attractive contrasting panel effects. Once installed, they are resistant to impact damage and require virtually no maintenance.
Oscar Acoustics has a range of products to suit most acoustic projects, with attractive spray applied acoustic decorative finishes from textured to plaster smooth, plus a range of SoundBlox and recently introduced are attractive acoustic panels to compliment the other products, Oscar has the answer to perfect sports hall acoustics.
