| 20100307867 | Buffering and Sound-Absorbing Member - The object of the present invention is to provide a shock and sound absorbing member having excellent shock and sound absorbing properties for use of a car etc. The shock and sound absorbing member comprises a core panel | 12-09-2010 |
| 20110168484 | SYSTEMS AND METHODS FOR PROVIDING AN ASYMMETRIC CELLULAR ACOUSTIC DIFFUSER - The present invention relates to providing an acoustic diffuser. In particular, the present invention relates to systems and methods for providing an asymmetric cellular acoustic diffuser adapted to diffuse sound waves that encounter a surface. Further, the present invention relates to providing a system of asymmetric cellular acoustic diffusers adapted to diffuse sound waves that encounter one or more surfaces in an acoustic environment. In some embodiments, an acoustic diffusion device as contemplated herein includes a planer panel having a first portion and a second portion, the first portion and the second portion each having a plurality of cells formed asymmetrically thereon. In such embodiments, the plurality of cells of the first portion is symmetrically oriented in relation to the plurality of cells of the second portion. | 07-14-2011 |
| 20120118665 | ACOUSTIC ENERGY REFLECTOR - The present invention relates to an acoustic energy reflector comprising a microcellular rubber as inner liner and a fiber reinforced composite as outer casing, in a core-shell assembly, wherein the said microcellular rubber is selected from the group of natural and synthetic rubbers having glass transition temperature below 0° C. and the resin for the fiber reinforced composite is selected from a group having a glass transition temperature at least 50° C. | 05-17-2012 |
| 20130133977 | ACOUSTIC PANEL FOR A TURBOJET ENGINE NACELLE, WITH IN-BUILT FASTENERS - An acoustic panel is provided that includes at least one cellular core arranged between at least an internal skin and an external skin, wherein the external skin incorporates at least one fastener able to collaborate in a disconnectable fashion with a complementary fastener associated with a structure to which it is to be attached. | 05-30-2013 |
| 20160104472 | ACOUSTIC AND VIBRATIONAL ENERGY ABSORPTION METAMATERIALS - A substantially acoustically transparent planar, rigid frame divided into a plurality of individual, substantially two-dimensional cells is used to construct a sound absorption panel. A sheet of a flexible material is fixed to the rigid frame, and a plurality of platelets fixed to the sheet of flexible material such that each cell is provided with a respective platelet, thereby establishing a resonant frequency, establishing an increase in an absorption coefficient of the panel. The flexible material has a wrinkle or corrugation to permit distortion with reduced material elasticity. The wrinkle or corrugation permits the flexible material to distort beyond that afforded by a planar material of the same type, while retaining mechanical strength in supporting the plurality of platelets. | 04-14-2016 |
