About Audio3 Ltd.


Audio3 Ltd. is a London-based company founded, owned and operated by hearing research scientists and clinical hearing professionals who study noise-induced heaing loss (NIHL) as a profession. We are dedicated to reducing the prevelence NIHL so our primary concern is your hearing health. We provide consulting services for the UK to reduce occupational noise by providing (1) on-site noise measurements, (2) hearing screening with audiometric and OAE measurments in conjuction with the UCL Ear Institute and (3) acoustic advice on reducing noise and vibration.

Our recent collaboration with the Royal College of Music in London has resulted in the creation of the soundBADGE. The smallest, least expensive and easiest to use noise dosimeter/sound level meter available....it is also one of the most accurate due to our true RMS technology.
