Abstract (en)
[origin: WO2010133812A1] The invention relates to an acoustic device including an acoustic contact microphone (4), an arch (10) for maintaining the microphone (4) against a side of the skull, said microphone (4) including a transducer for mechanically stimulating bone, wherein the transducer can receive a sound signal from the vocal cords by bone conduction and convert said sound signal into an electric signal. The acoustic device is characterized in that it comprises, connected to the transducer output, an electronic corrective filtering circuit for applying, depending on the frequency, a correction coefficient to the electric signal generated by the transducer in order to obtain a corrected signal that differs by only 10 decibels from the electric signal of an aerial acoustic microphone detecting variations in air pressure.
