Herein investigated are computationally simple microphone-array beamformers that are independent of the frequency-spectra of all signals, all interference, and all noises. These beamformers allow the listener to tune the desired azimuth-elevation "lo...

Street canyons are common in modern cities. It is well known that the multiple sound reflections within the canyons tend to increase the noise levels inside the canyons. An scaled down model experiment was conducted in the present investigation to st... Read More about Sound fields inside street canyons with inclined flanking building façades.
