Latest Patents

Hannu Nykänen holds a patent for a "Method and equipment for attenuating sound in a duct." This invention involves detecting sound in a duct using a detector and attenuating it through two successive monopole elements. These elements function as a dipole approximation, producing the necessary monopole radiation. A dipole control signal is applied to both elements with a 180° phase shift, while a monopole control signal is also fed to the same elements in a cophasal manner. The total volume velocities generated by the two elements are a combination of the contributions from both monopole and dipole sources.
