Sound Quality Subjective Evaluation Analysis of Noise Inside High-speed Trains
2012
Proceedings of the 1st International Conference on Mechanical Engineering and Material Science
unpublished
The paper studied paired comparison method, system researching experiments design, process, data analysis, and misjudgment analysis, etc. Paired comparison method has their own advantages; experimental data reliability and accuracy need to be further validation. The paper using Pearson correlation coefficient to verify the data accuracy and correlation coefficient is more than 0.72.At the end, preference value of sound samples is inverse proportion to loudness, as to A written right pressure
