The NoiseMasterTM active
headset
Strong points
- Acoustic performances
: Exceptional attenuation of fatiguing low frequency noise
(> 120 dBA)
- Hygiene - Safety - Quality
: Lower risk of deafness induced by low-pitched noise.
Reduces fatigue caused by aural strain. Increases quality of work carried out in high
noise level area.
- Psychoacoustics
: Allows normal, high-fidelity listening, without distortion of
exterior noise and audio transmission.
- Communication
: High audio transmission comprehension quality in noisy areas due to
the cancelling of outside noise by active electronic noise cancelling.
- Comfort
: Elimination of the feeling of acoustic confinement
The TechnoFirst active headset is in exhibition at "Cité des Sciences et de
l'Industrie" (Porte de la Villette, PARIS).

The LITE High-Fidelity headphone
 |
Le LITETM (TF-1060) hi-fi
headphone benefits from the technology of professional NoiseMaster headsets, and provides
an attenuation of external noise from 10 to 15 dB in the 20 to 1000 Hz frequency range.
Suitable for listening to music in a noisy environment (plane, train,...) Performances and technical data |
How does it work ?
All of our headsets are based on active
noise control More precisely, the loudspeaker (1) placed inside each earcup emits the
cancelling noise (2) which is phase opposed to the external noise (3). The result is noise
cancellation at the entrance of the ear canal (4). An analog electronic circuit (5)
generates appropriate cancelling noise by using a microphone (6) placed at the entrance of
the ear canal (feedback control) .
