Method for accurately adjusting and evaluating automobile sound

Abstract

The invention aims at providing a method for accurately adjusting and evaluating an automobile sound. The method comprises the following steps of: leading the performance indexes of a host and a loudspeaker to meet respective designing requirements; testing the overall performance index of the automobile sound; and if the overall performance index obtained by testing can not meet the corresponding designing requirement, leading the overall performance index to meet the corresponding designing requirement by adjusting a characteristic parameter of the loudspeaker. According to the better embodiment of the invention, a systematic adjusting mode with first part and second complete machine is adopted for an automobile, so that not only is the debugging efficiency improved, but also the effect of the automobile sound is guaranteed. In addition, since a hearing evaluation result is also introduced as an adjusting objective at the later-stage adjustment, the effect of the automobile sound can adapt to the preferences of different consumer groups.

Description

technical field [0001] The invention relates to the automobile electronic technology, in particular to a method for adjusting the automobile audio system. Background technique [0002] At present, the adjustment and evaluation of car audio are generally based on subjective and objective methods. Some manufacturers mainly rely on the subjective listening method to adjust and evaluate the vehicle audio. The defect of this method is that the subjective evaluation is often subjective, and it is easy to cause stereotypes of sound orientation, which cannot fully represent all age groups or various groups. The voice preference of consumer groups; in addition, subjective evaluation is closely related to the psychological factors of the evaluator and the external environmental factors of the evaluation, making the evaluation results easily interfered by psychological and environmental factors, thus affecting the authenticity and accuracy of the evaluation. Some manufacturers mainly ...

Some manufacturers mainly rely on the subjective listening method to adjust and evaluate the vehicle audio. The defect of this method is that the subjective evaluation is often subjective, and it is easy to cause stereotypes of sound orientation, which cannot fully represent all age groups or various groups. The voice preference of consumer groups; in addition, subjective evaluation is closely related to the psychological factors of the evaluator and the external environmental factors of the evaluation, making the evaluation results easily disturbed by psychological and environmental factors, thus affecting the authenticity and accuracy of the evaluation

Some manufacturers mainly rely on objective testing equipment for vehicle audio adjustment and evaluation. The disadvantage of this method is that although objective testing can specifically reflect many performance indicators, the performance indicators cannot completely replace the sense of hearing of the human ear, such as sound The human ear's sense of hearing such as layering and clarity cannot be reflected by objective indicators; moreover, personal sound preferences cannot be reflected by objective indicators, which makes the adjustment work difficult
