Acoustic Isolation of Gymnasia

A gym by its very nature is a place where people participate in noisy activities – running, jumping, shouting, ball sports and weight lifting etc are all part of typical gym usage; any construction must withstand this treatment whilst maintaining acoustic separation to prevent noise and structural vibration transmission.

Of primary consideration are nearby rooms- above, below or adjacent to the gymnasium. The comfort of the people in these rooms, especially sensitive areas such as IT centres, offices, auditoria, residential or libraries mean that the gym will require acoustic and vibration isolation. In these situations it is imperative to consider isolating the flooring from the main structure and if necessary we may also recommend additional isolation for the walls and ceilings and sometimes it may be necessary to isolate separate parts of the same room, for instance a running machine or free weights area.

Floating Floor Types

There are several types of floating floor systems available to provide acoustic separation. Depending upon your needs you may choose one over another. A popular choice for a gymnasium is a sprung wooden floating floor, which is very effective for aerobic and dance studios. For more demanding applications a spring or LDS (Low Dynamic Stiffness) rubber jack up concrete floating floor may be deemed more suitable. These floors are stronger more effective at absorbing dynamic loads and can be covered with different finishes to achieve the owner’s requirement.

Isolated Walls

If necessary, we can also isolate the walls of a gym. This can be done in one of two ways; firstly they can be built directly onto the floating floor (known as the ‘Box in a Box’ technique). Or, separately use SWW wall isolating plates at the base and AB-716 head restraint at the top. Acoustic sway braces can be attached in-between, tying resiliently the internal acoustic wall to the external building structure. The use of these products also creates an air gap which increases the acoustic performance.

Suspended Ceilings

A suspended ceiling may also be required; forming the ‘lid’ of the acoustically isolated box. There are several types of acoustic hangers available and for standard suspended ceilings we recommend the use of our HDQF hangers, which are available in either spring or L.D.S rubber. The HDQF hanger has been designed to easily clip onto the main support channel section of the ceiling grid system making it quicker, easier and a more reliable installation saving time and money for the contractor.
