Silence is Golden

With mixed-use buildings now the norm the reduction of audible structure-borne sounds is vitally important, and understanding the design and science of sound is an essential component to any gym design. The most important consideration is how sound, and energy will travel within your gym.

Noise can be transmitted through a building in a wide range of airborne and structure-borne methods. A good example of air-transmitted noise would be music that slips under doors during an aerobics class or the grunting of a weightlifter pushing themselves further. Structure-borne noise usually occurs with the impact of a blunt force object into the floor or the vibrations of cardio machines. The shock and vibration energy will transfer through the rigid building structure itself and easily into neighbouring spaces. There are two major sound influencers; construction materials and people/equipment.

Construction Material

You must have a holistic approach to noise mitigation and take into account the construction materials of not just your own space, but of adjoining spaces.

Every physical element of a fitness center influences its ability to funnel, absorb or reflect noise:
1. Shape – the corners and curves of surface walls, ceilings and floors
2. Material – cement walls, drywall and drop ceilings, vinyl flooring, interior doors and electrical outlets
3. Equipment – hard, sound-reflective gym equipment

The Effects of People & Equipment

When a weightlifter drops a dumbbell, the energy produced will travel anywhere it can. In most cases, the acoustics of a fitness center will allow the sound to travel under floor mats, through walls and beyond ceilings, disrupting those using adjourning rooms, businesses or living spaces.

The effects of noise from people and equipment go far beyond weights. Circuit training, treadmills, spin classes, dance, CrossFit and aerobics all create unique challenges.
