For materials that absorb incident sound energy, sound-absorbing materials are mainly used to control and adjust indoor reverberation time, eliminate echoes, improve indoor listening conditions, reduce noise in noisy places, and improve living environment and working conditions (see sound absorption reduction noise); it is also widely used to reduce noise in ventilation and air conditioning ducts.
With the prosperity and hustle and bustle of the city, people's lives have begun to enrich, but for some street owners, they can't help but worry that how to reduce noise has become a topic of their concern. The emergence of sound-absorbing materials has solved this problem well, so which is better? Come and see today!
Improve the sound insulation effect of thin walls. Such as gypsum board, calcium silicate board, FC board, TK board, fire-resistant magnesium cement board, etc., the interlayer can be filled with porous sound-absorbing materials such as glass wool, rock wool, mineral wool, etc., so as to improve the sound insulation effect of this board wall.
For materials that absorb incident sound energy, sound-absorbing materials are mainly used to control and adjust indoor reverberation time, eliminate echoes, and improve indoor listening conditions; they are used to reduce noise in noisy places and improve living environment and working conditions (see sound absorption reduction noise); it is also widely used to reduce noise in ventilation and air conditioning ducts.
Flexible materials that absorb sound by resonance (e.g. closed-cell foam, absorbs mid frequencies), film-like materials (e.g. plastic film or cloth, canvas, linoleum and artificial leather, absorbs low and mid frequencies), plate-like materials (e.g. plywood, hardboard, asbestos) Cement boards, gypsum boards, etc. absorb low frequencies) and perforated boards (made by perforating various sheet materials or metal plates to absorb medium frequencies).
Although the car weather strip is a small part in the body, it can ensure the stability and weight of the door opening and closing, and can also protect the car from wind, rain and dust, heat and sound insulation, and play the role of decoration at the edge of the door and window junction. Effect, when the body is subjected to vibration and deformation, the sealing strip also plays the role of buffering, shock absorption, and protecting the glass. Therefore, car maintenance is not a trivial matter, and any link cannot be ignored.
