| Abstract: A method and apparatus for determining a direction of infrasound.
Infrasound is received by a directional infrasound sensor comprising a
plurality of channels and a plurality of sensor devices. Each channel in
the plurality of channels comprises a single opening at a first end of
the channel and a closed end opposite the opening. The opening of each
channel in the plurality of channels is pointed in a different direction
from the opening of each other channel in the plurality of channels. The
plurality of sensor devices includes a sensor device at the closed end of
each channel in the plurality of channels. Each sensor device in the
plurality of sensor devices is configured to generate a sensor signal in
response to pressure. The sensor signals generated by the plurality of
sensor devices are processed to determine the direction of the infrasound
received by the directional infrasound sensor. |
