Researchers at the University of Alaska Fairbanks have developed a more powerful infrasound sensor that is reduced in size to the size of a hockey puck.
The new design removes the impact on infrasound measurement caused by changes in altitude. Therefore, the invention can be mounted on platforms that move, such as buoys, unmanned vehicles or high-rise buildings.
This sensor is the subject of a pending US non-provsional patent application entitled Noise Reduction in Infrasound Detection “US Patent Application Number 14,057,704”.
