TechnoFirst Noise-Cancelling headset

TechnoFirst, a specialist in noise reduction technology, presents its NoiseMaster headset, a patented system designed for people working in very noisy environments.

The NoiseMaster is an active acoustic protection helmet that enhances low-frequency sound reduction where the shells are ineffective and improves the intelligibility of communications and warning signals on-site. The device consists of a shell equipped with an internal microphone which picks up the noise not treated by the traditional shell. This is connected to a miniature electronics, which drives a small loudspeaker, positioned near the ear, to provide real-time active anti-noise.

The NoiseMaster is available in several configurations (communicating or non-communicating). It operates on batteries or on-board power supply. In normal mode, it has a good autonomy of 24 hours. It is also compatible with Talkie-Walkie, radio, and MP3 equipments. It is intended for heavy industries like concrete works and machine operators.
