New Eavesdropping Technology Raises Privacy Concerns

/ 1 min read

🔍 SuperEar: A New Privacy Threat Using Acoustic Metamaterials. Researchers have developed SuperEar, an innovative eavesdropping technology that utilizes acoustic metamaterials to covertly capture phone conversations from a distance. This system addresses previous limitations of acoustic metamaterials, achieving a 20-fold amplification of speech signals while minimizing audio distortion. SuperEar’s design enhances portability and concealability, making it particularly effective for outdoor surveillance. Experimental results indicate that it can accurately eavesdrop on conversations with over 80% accuracy from up to 4.5 meters away, highlighting its potential for real-world applications and raising significant privacy concerns.
