The invention relates to a method for masking undesired interference noise (2) occurring during operation of a vehicle (1) by means of a synthetic noise (3), the synthetic noise (3) being generated by an unmodulated synthetic noise (3.1) for adjusting a desired sound characteristic by multiplying with at least one filter (5) and/or amplifier (6) dependent on a vehicle parameter (4), wherein the tones of all the acoustic signals (8) constituting the modulated composite noise (3.3) are kept constant during the output of the modulated composite noise (3.3). The method according to the invention is characterized in that the unmodulated resultant noise (3.1) is formed as 1/f noise and is pre-modulated by at least one static filter (7) before being modulated by at least one filter (5) and/or amplifier (6) dependent on the vehicle parameter (4).
本发明涉及一种用于通过合成噪声(3)掩盖在车辆(1)运行期间出现的不期望的干扰噪声(2)的方法,其中合成噪声(3)由用于调节期望的声音特性的未调制的合成噪声(3.1)通过与至少一个依赖于车辆参数(4)的滤波器(5)和/或放大器(6)相乘而产生,其中在调制的合成噪声(3.3)的输出期间保持构成调制的合成噪声(3.3)的所有声学信号(8)的音调恒定。本发明的方法的特征在于,未调制的合成噪声(3.1)形成为1/f噪声,并且在由至少一个依赖于车辆参数(4)的滤波器(5)和/或放大器(6)进行调制之前通过至少一个静态滤波器(7)进行预调制。
