This line of research into how insects hear sounds using specialized, microscopic hairs could inspire a new generation of acoustic tools. Standard microphones are devices that contain membranes within them that can detect sound pressure levels. By mimicking these biological systems, such as using structures like these hairs in place of membranes, future microphones could be designed to instead measure the air particle velocity caused by sound, alongside the sound pressure levels.
