Latest Patents

Uosukainen's latest patents include a method and equipment for attenuating sound in a duct. This invention involves detecting sound propagation in a duct and utilizing two successive monopole elements to achieve sound attenuation. The 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 elements in a cophasal manner. The total volume velocities produced by these elements are a combination of the contributions from both monopole and dipole sources. Another significant patent is a sensor for measuring acceleration and sound pressure. This sensor comprises two concentric pressure-sensitive films, allowing for simultaneous measurement of pressure and acceleration at the same point, thus eliminating any phase difference between the two measurements.
