<p>The invention relates to a method and an arrangement for attenuating noise by antinoise. According to the invention the object is to attenuate the noise by weighting such frequencies, at which the noise is most disturbing. At other frequencies the noise is attenuated less or not at all. This saves power in the equipment and a stronger subjective attenuation is obtained that without frequency weighting. The system can be applied in a mobile station so that the speech heard from the mobile station can be distinguished from the environmental noise. <IMAGE></p> |
