A new earplug can now serve as hearing protection, a music player, and a microphone – all at once! At the heart of this technology is a MEMS chip developed at SINTEF in collaboration with Minuendo.

Hearing loss is irreversible and the most common work-related injury worldwide. Prevention is the only way to tackle this issue. But who has not been annoyed by how foam earplugs make a rock concert sound muffled and bass-heavy? Or struggled to hear a colleague when wearing bulky ear protectors in a noisy workplace?
