Latest Patents

Mase holds a patent for a "Method and apparatus for estimating sound source." This invention involves sampling sound and image data simultaneously using a specialized unit that incorporates multiple microphones and a camera. The sound pressure waveform data and image data are stored for further analysis. The system allows for the extraction of sound pressure waveform data, which is then used to display a time-series graph of sound pressure levels. By designating a specific time point on the graph, Mase's method calculates sound direction by analyzing phase differences between the sound signals captured by the microphones. The result is a sound source position estimation image that visually represents the estimated sound direction alongside the corresponding image data.
