Sennheiser aims to curb NIHL for broadcast professionals
Monday, February 24, 2014
Sennheiser claims its new HD25 range with LimitEar technology will help broadcasting professionals protect their hearing against noise induced hearing loss (NIHL) without compromising on reproduced sound quality. Sennheiser is the first company to market LimitEar’s ground-breaking HDM Pro® device which enables sound levels to be adjusted dynamically to reduce the impact of NIHL.
LimitEar’s patented Hearing Dose Management® technology goes beyond the functionality of the limiters currently available to the market, which simply cap sound levels. The HDM Pro device intelligently changes users’ sound levels through the day to ensure that their exposure to reproduced sound stays within legally defined limits.
Broadcasters are particularly at risk of NIHL, due to wearing headsets, headphones and earpieces for long periods, often in variable levels of ambient noise. EU regulations state that workers should not be exposed to average noise levels of 85dBA over an eight hour period.
Tim Sherratt, Engineering & Technical Services manager at Sennheiser UK commented, “We continually look to improve our products so we jumped at the chance of integrating LimitEar HDM Pro technology into our headphones. Other sound management solutions are crude and only limit the sound volume, which can cause operational difficulties when ambient sound is variable. LimitEar’s solution is smart; it monitors sound levels during the day and adjusts volume dynamically whilst staying within legally defined limits.”
