Sennheiser introduces HDM Pro technology

Sennheiser has introduced new technology to its HD25 headphone range, with the aim of helping to protect users’ hearing against noise induced hearing loss (NIHL), and improving reproduced sound quality. Sennheiser Solutions is the first company to market LimitEar’s HDM Pro device, which enables sound levels to be adjusted dynamically to reduce the impact of NIHL.

The HDM Pro device 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, and EU regulations state that workers should not be exposed to average noise levels of 85dBA over an eight-hour period.

“We continually look to improve our products so we jumped at the chance of integrating LimitEar HDM Pro technology into our headphones,” said Tim Sherratt, engineering and technical services manager at Sennheiser UK. “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.”

Stephen Wheatley, managing director at LimitEar, added: “Professionals in the broadcast and live events industry are often restricted by limiters on their headphones which is far from ideal. Together with Sennheiser Solutions, we’re offering the best hearing experience that’s still within regulation, minimising the impact of noise induced hearing loss.”
