Description
Technical Field
The utility model relates to the technical field of indoor suspended ceilings, in particular to a novel indoor sound absorption suspended ceiling system for a building.
Background
Suspended ceiling refers to a decoration of the top of the living environment of a house. The decoration pursuit of the suspended ceiling has different understanding in different ages, from ancient and antique old buildings to modern buildings which are exquisite and fashionable nowadays, no figure of the suspended ceiling exists, the building development of hundreds of years is carried out, and the suspended ceiling is subjected to the transition and reform of the generation. From ancient times, people attach great importance to roof decoration, ranging from the most popular "algae well" in ancient times to the very crude woven bags, plastic color strip paper ceilings, and the like. With the time of the alternation, lime smallpox began to prevail in the last 50 th century, and nearly modern household suspended ceiling decorations also experienced wave-by-wave tide.
At present, modern suspended ceilings have been developed to be mainly composed of gypsum boards, mineral wool boards, PVC plastic boards, aluminum pinch boards and metal integrated suspended ceilings. The function industry of suspended ceilings is developed from the original decorative components to modern functions of heat preservation, heat insulation, sound insulation and sound absorption, and is also a concealed layer of engineering such as electric, ventilation and air conditioning, communication and fireproof, alarm pipeline equipment and the like.
In recent years, with the improvement of national living standard, people have put higher demands on the control of vibration and noise in various building sites.

When inside a building, air and solid sounds can generally be mutually converted, as the vibration of the air sound can force the member to vibrate into a solid sound, which when radiated out of the sound also becomes an air sound. The reduction of the transmission of air sound starts from the reduction or prevention of the vibration of the air, and the reduction of the transmission of solid sound must adopt a vibration isolation or damping method.
At present, the action principle of the sound absorption (or sound insulation) suspended ceiling mainly aims at the characteristics of noise transmission, and the purposes of comprehensively improving the indoor sound environment and isolating noise interference are achieved through the combination and arrangement of specific structural layers and the collocation and use of various building materials with good sound absorption (sound insulation) performance.

Detailed Description
The utility model is described in further detail below with reference to the drawings and the specific examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
Sound insulation: sound insulation refers to a measure that when sound waves propagate in air, various substances which are easy to absorb energy are used for consuming the energy of the sound waves, so that the sound energy is blocked in a propagation path and cannot directly pass through the propagation path, and the measure is called sound insulation.
Vibration isolation: suitable elastic means are employed to isolate the vibration.
Sound absorption: after sound enters the porous material or causes the flexible deformed plate to vibrate, the acoustic energy is converted into the effect of thermal energy. It is classified into air sound absorption and material sound absorption. The phenomenon that sound waves are spread in the air and the sound energy is converted into heat energy due to vibration friction of air particles, and the sound waves are gradually attenuated along with the increase of the propagation distance is called air absorption and sound absorption; when sound waves are incident on the porous sound absorbing material, a substantial portion of the sound energy is converted to heat energy to be absorbed, due to the viscous drag of the air, which is in vibratory friction with the walls of the holes, known as material sound absorption.
Air sound: the vibration of surrounding air particles is caused by the vibration of a sound source, and the surrounding air particles are spread out in the form of longitudinal waves with alternate densities. It can be transmitted to adjacent or farther rooms from corridor or door window entrance and pipeline and hole gap; vibration of the wall and floor slab may also be excited to transmit acoustic energy to an adjacent chamber.
Solid sound: the noise is generated by directly transmitting vibration energy to the building structure by directly contacting the vibrator of the sound source with the building structure or by directly transmitting the vibration energy to the solid between the solids. Noise heard under the floor is, for example, solid sound due to walking of people on the floor, furniture movement, and the like.
Reverberation: when the sound wave propagates indoors, the sound wave is reflected by barriers such as walls, ceilings, floors and the like, and each reflection needs to be absorbed by the barriers. Therefore, after the sound source stops sounding, the sound waves are reflected and absorbed for a plurality of times in the room and finally disappear, and the sound source is perceived to be mixed with a plurality of sound waves for a period of time after the sound source stops sounding (the sound continuation phenomenon still exists after the sound source stops sounding in the room). This phenomenon is called reverberation and this period is called reverberation time.
Keel: is a building material for supporting modeling and fixing structure. The method is widely applied to indoor decoration, ceilings and other positions. Is a decorated framework and a decorated substrate, and is very commonly used. The keels are various and can be divided into wood keels, light steel keels, aluminum alloy keels, steel keels and the like according to different manufacturing materials.
