Our approach
Detecting sonic booms
Technical approaches to detect and measure sonic booms, and the portable device we are building to do it around the clock.
The challenge
A sonic boom is not like ordinary noise. Its energy sits in the 0.1–100 hertz range, so standard audio equipment and smartphones cannot accurately record, measure or play it back. Detecting booms reliably means purpose-built sensors that can capture very low frequencies, together with software that can tell a genuine boom apart from a passing truck or a slammed door.
What we are building
We are working to create a portable, easy-to-use device that will help detect sonic booms. Prototype devices are currently housed in Pelican Micro Cases, and we are looking at small solar arrays with lithium battery storage so that each unit can run unattended. Our goal is 24x7 device operation.
