Acoustic engineering refers to the calculation of the sound absorption degree of each material before the construction of the music hall. This is one of the most basic projects, including: acoustic decoration, home sound insulation and noise reduction, pump room noise control, and sound insulation and sound absorption materials Sales are supplemented by multiple implementation projects. Various acoustic decoration, home improvement and tooling sound insulation and noise reduction, computer room noise control engineering and sales of sound insulation, sound absorption and vibration damping materials, and provide practical construction plans. The specific undertakings are as follows: Urban area civil buildings, air-conditioned machine rooms, garages, exhibition halls, hotels, restaurants, shopping malls, supermarkets, hospitals, office buildings, etc. Environmental noise control, sound insulation and anti-vibration projects
Air conditioning host noise reduction
The hazard of noise to sleep: Sudden noise at 40 decibels can wake up 10% of people, and when it reaches 60 decibels, 70% of people can wake up.
Noise hazard
◆ The hazard of noise to hearing: Noise can cause tinnitus, deafness and hearing loss. When it exceeds 55 decibels, it feels noisy. After long-term exposure to noise above 85 decibels, the incidence of deafness will be 20% after 40 years.
Hearing hazards of noise
◆ The harm of noise to the physiology: Noise can cause nervousness, arrhythmia, and blood pressure. Under high noise environment, it will cause some women’s sexual dysfunction, menstrual disorders, and increase the abortion rate of pregnant women.
◆ The harm of noise to children: Noise can hinder the development of children’s intelligence. Children in noisy environments have 20% lower intellectual development than children in quiet environments.
The harm of noise to children
The principle of noise control is to adopt measures such as damping, sound insulation, sound absorption, and building layout before the noise reaches the eardrum, try to reduce the vibration of the sound source, absorb the sound energy in transmission, or set up obstacles to make the sound all or part of it Reflected out, so as to achieve the result of noise reduction.
Noise Control Project
Sound-absorbing board decoration
Jiayin supplies sound insulation materials, sound-absorbing materials, and professionally undertakes noise control projects such as home sound insulation and noise reduction projects, including function halls, discos, theaters, music rooms, classrooms, laboratories, recording studios, piano rooms, sound insulation partitions, and sound insulation ceilings , Soundproof walls, soundproof floors, soundproof windows, soundproof doors and other projects. At the same time supply sound insulation materials and a variety of noise reduction and sound absorption materials, engineers will solve the noise problems in the environment at any time for you
