A system and method for determining a characteristic of a noise source. A first array of microphones is mounted on a platform moveable from a starting position to an ending position along a line parallel to a central axis of the noise source. A second array of microphones includes sound sensors mounted in a spaced apart fixed position with respect to the noise source. A processing system processes first information from the first array of microphones and second information from the second array of microphones. The processing system collects and stores the first and second information at each discrete step of the first array, spatially filters the first information, processes and calibrates the filtered first information based on the second information, and further processes the calibrated first information to obtain a characteristic at a selected location. For flyover testing, the first array is instead held in a fixed position.
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
