Researchers at the Trondheim-based company Nacre AS some time ago developed a new system for protecting the ears against loud noises. Fro example, Norway’s largest company, Statoil ASA, is currently peddling the product to its employees, who need to work in extremely loud conditions aboard drilling rigs. The Nacre AS innovation, which draws its roots from work conducted at SINTEF, Scandinavia’s largest independent research organization, is also being distributed to the US military, in addition to other unspecified customers.
Experts say that the QUIETPRO earplug system is the world’s most advanced hearing protection device, capable of filtering out incredibly loud noises, AlphaGalileo reports.
Their development was extremely important for the oil industry, seeing how more than 600 cases of hearing impairment are reported by the Norwegian petroleum industry annually.
It features an external microphone, capable of picking up ambient sounds, and relaying them to a small loudspeaker inside the ear. Additionally, the plugs also contain a microphone inside the ear, which captures the words of its wearer from inside the skull.


But capturing words with a microphone placed in front of the lips also captures a lot of the ambient noise, which is not something you want to do on an offshore drilling rig. The expert is the initiator and manager of the Offshore Safety for Hearing and Verbal Communication (SoHot) research & development project. Two studies here and here show that taking N-acetylcysteine (NAC) after being exposed to loud noises can prevent noise-induced hearing loss (NIHL). Shearing forces caused by any sound have an impact on the stems of the hair cells of the basilar membrane of the cochlea (the inner ear), and if excessive these forces can cause cell death. NAC works in protect the ear due to NAC's function as an potent antioxidant, protecting human cells from damage in a wide variety of scenarios.
Their innovation is currently being used in applications varying from the military to the oil industry. In the mean time, the sound is processed on board, and the noises are eliminated digitally.
