With a remarkable portfolio of 8 patents, Ichihashi has focused on developing innovative solutions aimed at noise reduction using advanced acoustic structures.

Latest Patents

Among his latest inventions, Ichihashi has designed a pioneering "Stepped Acoustic Structure with Multiple Degrees of Freedom." This acoustic structure is engineered to significantly reduce noise generated from various sources. It features acoustic septum caps anchored at uniform depths within the cells of the structure. By placing steps within the cells, which decrease the cross-sectional area, the invention enables multiple degrees of acoustic freedom. Additionally, depth control portions are incorporated into the septum caps, allowing for the successful positioning of septum portions at varying depths, thereby enhancing the acoustic performance of the structure.

Another notable patent is the "Acoustic Structures with Multiple Degrees of Freedom." This invention maintains the same concept of integrating adjustable depth control portions within the acoustic septum caps. These variations facilitate the organization of septum portions at different depths, thus achieving an enhanced acoustic structure that optimally reduces noise, even when the septum caps are installed at the same depth.
