Title: Masayuki Kurashina: Innovator in Sound Absorption Technology
Introduction
Masayuki Kurashina is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of sound absorption technology, holding 2 patents that showcase his innovative approach to improving sound insulation.
Latest Patents
One of his latest patents is a sound absorbing mechanism using a porous material. This invention features a sound absorbing plate made from a thin plate porous material, which is created by partially heating and welding plastic particles. The design includes a supporting member that forms a back air space, enhancing the sound absorption capabilities. The mechanism incorporates multiple pairs of resonators, each with a separated back air space, which are fixed to the sound absorbing plate. These resonators are strategically positioned opposite a sound insulator, with the supporting member placed in between. Additionally, the design allows for plural reflecting members or increased sound absorbers to be positioned opposite the surface of the sound absorbing plate that does not have the resonators. This innovative mechanism demonstrates superior sound absorption characteristics across a wide range of frequencies.
