Problems solved by technology

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 affectin

Example Embodiment

[0023] Hereinafter, the present invention will be described in detail based on the drawings showing embodiments of the present invention.

[0024] According to the embodiment of the present invention, the tuning method of the vehicle audio includes four processes. The first process is the test and evaluation of the speaker component level. The purpose is to ensure that the main performance indicators of the speakers meet the design requirements, so as not to affect the final sound effect of the vehicle. The second process is the test and evaluation of the host component level. The purpose is to ensure that the main performance indicators of the host meet the design requirements, so as not to affect the final sound effect of the vehicle. The third process is the objective test and evaluation of vehicle-level audio. Objective test evaluation is carried out when both the speaker and the host meet the design requirements. The purpose is to determine whether the interior environmen...

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 ...
