          Beijing Municipal Institute of Labor Protection
Beijing Municipal Institute of Labor Protection was founded in 1955. Noise and vibration control is one of its major fields. Over the past fifty years, it has armed with rich experience in scientific search and engineering practice, gets plenty of scientific and technological achievements (some of them was awarded first place, second place, and third place awards of technological advancement bestowed by either the ministry or departments) and developed various related products. Of its projects, low noise cooling tower in 1980¨s, noise control project for Beijing Sanyimiao Crossover in 1995, and heavy load damp spring vibration isolator in 2000 were awarded the second place prize of scientific advancement by the State Economic and Trade Commission. Experts of the institute published a number of books on noise and vibration and implemented more than twenty national standards.
