Some hazardous area equipment should be seen, but hopefully not heard – for instance, you might hope you will never hear an alarm or siren go off unless it’s being tested.

But in some of the noisiest environments, there are certain types of hazardous area equipment for which being heard is part of the core functionality.

An example of this is when you need to make a telephone call from an industrial location or an exposed position on an oil rig.

In a working industrial environment, with unpredictable weather conditions, it’s not always easy to make yourself heard on a phone call unless you have the right equipment.

The GAI-Tronics Auteldac 4 is one wall-mounted telephone that knows how to get your attention, with a sounder capable of ringing at up to 90 dB.

Once in use, its noise reduction function can help to boost the voice signal over any surrounding turbulence in a busy or loud setting.

And with the addition of an acoustic hood over the telephone position, users have a physical cocoon to duck inside, blocking out a further 9 dB of background noise and making sure important calls can not only be made but also understood.
