The Ambrose Diaphonic Ear Lens (ADELTM), which looks like a tiny ear-sealing balloon, is a sacrificial membrane that disrupts excessive pressure waves, protecting the ear drum when in-ear listening devices are used. Developed by Asius Technologies, the research was supported in part by a grant from the National Science Foundation's Small Business Innovation Research (SBIR) program.
