Million of people are living in an environment that is seriously polluted by loud low frequency noise from a wide range of sources, such as motor vehicle, trains, airplanes, construction sites, duct ventilation, and elevator buzzes, etc.
Unlike the mid- and high-frequency noise, low-frequency noise has been the most difficult problem in the field of noise mitigation because of its meter-long wavelength. It has restricted the comprehensive management of noise and has been a serious global challenge of noise management.
Tranquility Acoustronics has been a forefront pioneer in the research and application of acoustic metamaterials, using the principle of locally resonant sonic materials*design principle to overcome the century-old problem of low-frequency noise reduction. It has not only achieved efficient control of noise in the full frequency band, but also greatly reduced the volume and weight of the sound insulation structures, greatly expanding the scope of noise mitigations.
As the world's leading noise management company, Tranquility Acoustronics mission is to achieve effective mitigation of all types of noise around the world, contributing the China solutions for all the people living in the noise pollution environment around the world.
