| 摘要 |
<p>The invention relates to an electric impedance synthesis method to be used in an electroacoustic device having broadband noise-reduction capacitors, which includes a step of defining the acoustic specifications on the basis of a complex specific acoustic impedance, which varies with the frequencies, and responds to requirements in terms of noise reduction; an analysis step which consists of determining the electrical, mechanical and acoustic parameters of one or more electroacoustic transducers in the noise environment thereof; and a synthesis step which identifies and implements the electric load impedance or impedances to be applied to the terminals of the electroacoustic transducer or transducers in order to provide the desired acoustic performance.</p> |
