| 网站简介： | Sonic Nets, a Benign Acoustic Deterrence, projects unique sounds that are no louder than a bird normally talks that make it hard for the birds to understand each other. Sonic Nets is also designed to use parametric speakers (an array of very small speakers) to shape the sound so no one else hears it - except the birds or animals you are targeting. |
