  • Non-linear dynamic absorber and use thereof for acoustic insulation
    Patent number: 10738464
    Abstract: A building element includes a sheet of a rigid material and at least one nonlinear energy sink including a blade with two end parts and a nonlinear spring function intermediate part, a mass fixed to the nonlinear spring function intermediate part of the blade, and a fixing element allowing the two end parts of the blade to be fixed to a solid support in such a way that the nonlinear spring function intermediate part can oscillate about its position of equilibrium or its positions of equilibrium. The nonlinear energy sink is fixed rigidly to the sheet by the fixing element. The building element can be contained in a partition wall. Additionally, such an energy sink or building element can be used for reducing the acoustic transparency of a wall.

  • AUDIO HEADSET WITH ACTIVE NOISE CONTROL, ANTI-OCCLUSION CONTROL AND PASSIVE ATTENUATION CANCELLING, AS A FUNCTION OF THE PRESENCE OR THE ABSENCE OF A VOICE ACTIVITY OF THE HEADSET USER
    Publication number: 20170148428
    Abstract: The headset includes an active noise control with an internal microphone (28) and an external microphone (32). A processor (42) comprises a feedback branch (46), adjusted so as to attenuate the low frequencies corresponding to a component of a voice signal transmitted by bone conduction, and a feedforward branch (58) adjusted so as to compensate for the attenuation introduced by the feedback filtering and the passive acoustic attenuation introduced between the outside and the inside of the headset. A voice activity detector (60) operates a dynamic switching between two couples (HFB, HFF) of different transfer functions applied to the feedback (46) and feedforward (58) functions. This allows rendering in the most natural way possible to the user all the external sounds, including his own voice.
