[0031] In order to facilitate the understanding of the technical content of the present invention, specific examples are described below in conjunction with the accompanying drawings.
[0032] Such as Figure 1-Figure 3 As shown, an annoyance evaluation method for the combined effects of vibration and noise in subway environment includes the following steps:
[0033] Step 1: Convert the vibration evaluation value from acceleration to vibration level according to the vibration level formula; then according to the Weber-Fechner law, the amount of human psychological perception is proportional to the logarithm of the physical stimulus, which can determine the person’s vibratory environment The degree of annoyance is linearly related to the magnitude of the vibration level; fuzzy mathematics is used to establish the basic membership function of human annoyance in a vibrating environment (see formula 1).
[0034] Step 2: Introduce the normal distribution function (see formula 3) to descr...
