Bone conduction Also in Scandinavia, Denmark’s Invisio prides itself on being a noise reduction specialist. Patented bone conduction technology is at the heart of its accessories for public safety and security, military, utility, industrial and transport applications. Standard and customized headsets, including dual in-ear
Invisio’s M3 in-ear tactical headset is claimed to provide
superior comfort and secure fi t, with total elimination of noise. It is compatible with eyewear, helmets, gas masks and hazmat suits
headsets, intelligent systems, PTT systems and custom-made solutions, all use its own technology, which, instead of using traditional sound wave technology, employs a small ear microphone to pick up vibrations from the user’s jawbone. T ese are converted to sound, providing – according to the company – crystal-clear speech even under extreme conditions with no need of a microphone or boom, and without interference from external noise. Bone conduction is also used by other manufacturers.
But Ole Konarski, of Invisio, explains: “Where Invisio has a worldwide patent is on having it the pickup of the vibration in the beginning of the ear canal – not to be confused with skull mics, throat mics, etc.! So Invisio Bone Conduction is defi nitely not just bone conduction.” And he adds: “When we talk about extreme environments
where this is widely used, it is correct that the bone conduction is essential in our headsets – but we are also pretty unique in the sense that we provide waterproof versions, heat resistant versions etc. And the latest addition, which we are launching right now, is an ATEX/IECEX version of our headset.” Other patented features developed by the company
include Invisio Soft Spring, which ensures that the headset stays securely and comfortably in place even for prolonged periods, and Invisio Cable Retainer.

distributor specialising in Motorola and Sepura equipment portfolio. It supplies a range of products designed for use with TETRA radios, predominantly for the emergency services and public safety agencies that have access to the UK’s Airwave network. Interestingly, the company states that its range of TETRA audio and carrying accessories is both OEM and non-OEM in origin to cater for the diff erent budgetary requirements of its customers. In Ireland, Sigma Wireless is the exclusive distributor for
Motorola TETRA products, including handsets such as Motorola’s Discreet TCR1000 Covert TETRA terminal, which is supported by the full range of TCR1000 accessories. Sigma also supplies products from the German emergency

Shopping around Can there be a conclusion in this vast area of the TETRA industry? I guess; but fi rst, to the very many players not mentioned above, our apologies, but the space available means you’re here in spirit, just not in text. To the end user seeking the best fail-safe accessory options,
by all means look fi rst to your OEM supplying your core equipment– but don’t shy away from reputable, non-OEM makers. T ere is some excellent product out there. Always check what standards any products meet, who’s
using them at present, and get a user opinion. And if your team of operatives have particularly big ears, remember, several makers off er tailor-made services, so do shop around and ask! Finally, when it comes to the lower-end suppliers, including
accessories you may fi nd in the darkest corners of the Internet, remember: as Motorola’s Iain Ivory said, “Buyer beware!”
