  • Noise damper and a method for producing a noise damper
    Patent number: 12338581
    Abstract: A noise damper for reducing noise from a vibrating element which vibrates at a vibrational frequency, wherein the noise damper is configured to be in contact with the vibrating element such that when the noise damper is in contact with the vibrating element a noise amplitude at a point in a surrounding of the vibrating element is given by an attenuation factor times the noise amplitude at the point in the surrounding when the noise damper is disconnected from the vibrating element, the noise damper comprising: a polymer matrix, the polymer matrix being in a solid phase and forming a shape; a plurality of hollow particles dispersed in the polymer matrix, each hollow particle having a shell encapsulating a gas filled cavity, each hollow particle having a hollow particle size, and the plurality of hollow particles being dispersed at a hollow particle concentration in the polymer matrix; wherein the hollow particle size and the hollow particle concentration are configured to set the attenuation factor below an at
