Problems solved by technology

Therefore, the present invention proposes a method for evaluating vehicle sound quality based on pupil diameter. By directly quantifying the pupil diameter index that can reflect the psychological load of the evaluator, it can make up for the defect of the proportional scale in the subjective evaluation method of sound quality, and solve the objective evaluation index of sound quality. Select the question of divergence

Embodiment

[0041] In order to facilitate a deeper understanding of this method, a specific implementation case is used to illustrate:

[0042] Step 1. Select a sound quality evaluator;

[0043] Step 2. Adjust the working condition of a certain type of motor vehicle to the working condition to be evaluated, complete the adjustment of the working condition, and fix the HMS III artificial head produced by HEADacoustics at the driver's position under the working condition of a certain type of motor vehicle to be evaluated , complete the fixation of the audio acquisition device, and use the SQlabII multi-channel test system to collect audio data s 0 As a sample to be evaluated, complete the collection of samples to be evaluated;

[0044] Step 3. The evaluator sits on the seat, wears HA III high-fidelity headphones, and plays back the collected audio data in the car s 0 , to collect sound quality evaluation data;

[0045] Step 4. Judging whether the illuminance-pupil diameter model of the...

Abstract

The invention discloses a method for evaluating vehicle sound quality based on a pupil diameter, and belongs to the technical field of vehicle testing. The method for evaluating the vehicle sound quality based on the pupil diameter is provided aiming at solving the deficiencies that by using a sound quality subjective evaluation method, multi-sample comparison or grading can only be conducted and a specific ratio scale can not be given, and a lot of differences exist in evaluation index selecting of a sound quality objective evaluation method. The method comprises the steps of firstly selecting a sound quality evaluator, collecting a sample to be evaluated, and conducting the sound quality evaluation; then judging whether there is an illuminance-pupil diameter model of the selected evaluator, if there is no model, standard pupil diameter data is collected, and the illuminance-pupil diameter model is generated; if there is a model, the model is utilized to be subjected to sound quality quantization with the sound quality evaluation data. According to the method, a pupil diameter index of the mental load of the evaluator can be reflected through quantization, the deficiency of a ratio scale in the sound quality subjective evaluation method is made up, and the problem of differences of the sound quality objective evaluation index selecting is solved.

Description

technical field [0001] The invention belongs to the technical field of automobile testing, in particular to a method for evaluating vehicle sound quality based on pupil diameter. Background technique [0002] At present, the evaluation of vehicle sound quality can be divided into subjective evaluation and objective evaluation. The subjective evaluation method of sound quality takes people as the main body, and conducts evaluation through questionnaire survey or subjective evaluation test by jury. The objective evaluation of sound quality is based on the physical parameters of the sound and the objective parameters of psychology, through testing and analyzing the objective parameters of the sound such as loudness, sharpness, roughness, and volatility to evaluate the quality of the sound. [0003] However, the subjective evaluation method of sound quality mainly evaluates the sound quality based on questionnaire survey, paired comparison method, and ranking method. scale sca...
