Nudging people to prevent hearing loss

Maintaining our hearing abilities is crucial for engaging with others and experiencing our surroundings. While the negative impact of noise on hearing is well known, people neglect to take appropriate measures to protect their hearing in everyday life. “hEar” is a wearable tool that measures sound intensity and alerts users in real-time when noise levels become “dangerous». Real-time feedback on noise exposure levels supports safe listening habits. The device encourages behavior change leading to enhanced quality of life.


The goal is to raise awareness and prevent noise-induced hearing loss with a lifestyle-oriented tool that nudges people to change their behavior.
