A floor is the bottom surface of a room or vehicle or even possibly the surface on which people dance, commonly referred to as a dance floor. Floors vary from simple dirt in a cave to many-layered surfaces modern technology. Floors may be stone, wood, bamboo, metal or any other material that can support the expected load.
Floating floors as used in sound studios can be either just larger versions of the domestic variety, or much larger constructions with slabs of concrete to keep the resonance frequency down. The manufacture of integrated circuits uses massive floating floors with hundreds of tons in weight of concrete to avoid vibration affecting mask alignment.
Nightingale floors are floors that make a chirping sound when walked upon. These floors were used in the hallways of some temples and palaces, the most famous example being Nijō Castle, in Kyoto, Japan. Dry boards naturally creak under pressure, but these floors were built in a way that the flooring nails rub against a jacket or clamp, causing chirping noises. It is unclear if the design was intentional. It seems that, at least initially, the effect arose by chance. An information sign in Nijō castle states that The singing sound is not actually intentional, stemming rather from the movement of nails against clumps in the floor caused by wear and tear over the years. Legend has it that the squeaking floors were used as a security device, assuring that none could sneak through the corridors undetected.
Raised Floor Design Many office buildings now use access flooring to create more flexible and sustainable spaces. When underfloor air is designed into a building from the start of the project, the building can be less expensive to build and less expensive to operate over the life of the building. Underfloor air requires less space per floor, thereby reducing the overall height of the building, which in turn reduces the cost of the building facade. The blowers and air handlers required for underfloor air are much smaller and require less energy, since hot air rises naturally through the space as it comes in contact with people and equipment that warm the air and it rises to the ceiling.
