Embodiment Construction

[0024] figure 1 A schematic diagram of the improvement of the noise quality by the method according to the invention and by the regulating or control device according to the invention is shown in . The graph shows the frequency spectrum in Hertz (Hz) on the X-axis and the sound pressure level in Decibels (dB) on the Y-axis. The better noise quality is shown in the upper curve 11 , and the original situation so far is shown in the lower curve 12 . An exemplary optimization scheme for the perception of subjectively perceived noise quality by boosting low frequency components is shown here.

[0025] figure 1 The exemplary diagram for improving the noise quality shown in is based on the method according to the invention for influencing the noise acoustics of an air-conditioning system of a vehicle. The method according to the invention includes reducing psychoacoustic variables of the air conditioning system, in particular the sharpness of the sound, by influencing low- and / or mi...

Abstract

A method for influencing an acoustic noise of an air-conditioning system of a vehicle, wherein a psychoacoustic variable, in particular a sharpness of the sound, of the air-conditioning system is reduced by influencing a low-frequency and / or medium-frequency spectral component of a frequency spectrum of the sound of the air-conditioning system. A regulating or control device for carrying out the method.

Description

technical field [0001] The invention relates to a method and a regulation or control device for improving the noise quality of an air conditioning system. Background technique [0002] In order to provide optimum comfort for the vehicle's occupants, modern vehicles often have an air conditioning system. The task of the air conditioning system is to provide the vehicle occupants with the desired interior air environment independently of the weather or waste heat. However, when this type of air-conditioning system is in operation, the equipment inside the air-conditioning system, especially the fan of the air-conditioning system that conveys air in the air-conditioning system will produce noise and sound effects. This noise sound effect is especially clear when the vehicle engine is stopped. Furthermore, as vehicle drives are becoming quieter, this noise sound effect is felt more strongly by the vehicle occupants, since the noise is not masked by the noise of the vehicle dri...
