Noise Mitigation Strategies For Vertical Sound Transmission in Buildings with Wooden Floor

Abstract  Sound transmitted vertically in buildings with wooden floors, whether airborne or impact sounds, gives limitations to occupant’s privacy and comfort in multistory structures. Meanwhile, excellent thermal qualities, affordability, and broad availability of hardwoods have made it an option for many structural components including flooring in the United States. In order to maximize all the advantageous properties of hardwood as a building floor, it is important to address challenges associated with the material such as vertically transmitted sounds among others.  This study explores various noise mitigation techniques, to be started with a thorough examination of the acoustic characteristics of hardwood slabs, highlighting important elements that influence sound transmission. It will further assess different strategies, such as installing floating floor systems, applying dampening compounds, and installing robust underlayments, all which have the ability to reduce the transfer of vertical sound through hardwood floors. The study also investigates the incorporation of sound-absorptive materials in floor spaces to further reduce noise, such as fiberglass insulation. The results are meant to assist acoustic engineers, architects, and builders in creating better vibration and noise control plans for modern timber buildings.
