The theoretical formula value is compared with the calculated value of statistical energy analysis (SEA) to verify its effectiveness in the prediction of sound barrier. And the insertion loss of sound barrier of mineral wool with diverse material thicknesses and coverage are calculated. The results showed that the noise attenuation of the sound barrier increased by 1.5 dB when the sound absorbing materials are attached to the sound barrier near the acoustic source. The noise attenuation effect of mineral wool is improved in the frequency band below 600 Hz when the thickness is increased. The coverage of mineral cotton increased by 25%, and the noise attenuation increased by 0.4 dB. Meanwhile, it also reflects the advantages of fast and convenient statistical energy analysis (SEA) \u2013 only one time modelling and changing its parameters can obtain the corresponding statistical results, which has some excellent reference function.<\/jats:p>","DOI":"10.3233\/jcm-215155","type":"journal-article","created":{"date-parts":[[2021,6,15]],"date-time":"2021-06-15T14:06:12Z","timestamp":1623765972000},"page":"737-745","source":"Crossref","is-referenced-by-count":3,"title":["Comparative noise reduction effect of sound barrier based on statistical energy analysis"],"prefix":"10.66113","volume":"21","author":[{"given":"Jiyong","family":"Jin","sequence":"first","affiliation":[]},{"given":"Congyun","family":"Zhu","sequence":"additional","affiliation":[]},{"given":"Rui","family":"Wu","sequence":"additional","affiliation":[]},{"given":"Yanming","family":"Liu","sequence":"additional","affiliation":[]},{"given":"Miao","family":"Li","sequence":"additional","affiliation":[]}],"member":"55691","reference":[{"key":"10.3233\/JCM-215155_ref1","doi-asserted-by":"crossref","first-page":"65","DOI":"10.4028\/www.scientific.net\/AMR.901.65","article-title":"Review of new city viaduct noise barrier","volume":"3530","author":"Zhou","year":"2014","journal-title":"Advanced Materials Research"},{"issue":"4","key":"10.3233\/JCM-215155_ref2","doi-asserted-by":"crossref","first-page":"65","DOI":"10.2478\/v10168-010-0043-z","article-title":"Performance of profiled single noise barriers covered with quadratic residue diffusers","volume":"35","author":"Monazzam","year":"2010","journal-title":"Archives of Acoustics"},{"issue":"11","key":"10.3233\/JCM-215155_ref3","first-page":"125","article-title":"Design and experimental tests of active control barriers for low-frequency stationary noise reduction in urban outdoor environment","volume":"114","author":"Francesco","year":"2016","journal-title":"Applied Acoustics"},{"issue":"12","key":"10.3233\/JCM-215155_ref4","first-page":"492","article-title":"Acoustic performance of noise barrier based on sonic crystals with resonant elements","volume":"155","author":"Jan","year":"2019","journal-title":"Applied Acoustics"},{"issue":"11","key":"10.3233\/JCM-215155_ref5","doi-asserted-by":"crossref","first-page":"294","DOI":"10.1016\/j.apacoust.2016.07.028","article-title":"Standardised acoustic characterisation of sonic crystals noise barriers: sound insulation and reflection properties","volume":"114","author":"Morandi","year":"2016","journal-title":"Applied Acoustics"},{"issue":"4","key":"10.3233\/JCM-215155_ref6","first-page":"76","article-title":"Environmentally friendly sound absorbing noise barrier made from concrete waste-further development","volume":"3","author":"Zbigniew","year":"2010","journal-title":"International Journal of Pavement Research and Technology"},{"issue":"3","key":"10.3233\/JCM-215155_ref7","first-page":"52","article-title":"Road-traffic noise and factors influencing noise annoyance in an urban population","volume":"35","author":"Jakovlijevic","year":"2009","journal-title":"Environment International"},{"issue":"3","key":"10.3233\/JCM-215155_ref8","first-page":"297","article-title":"A detecting method for line-spectrum target by fusing output DC jump to fluctuations ratio of sub-band spatial spectrum and beam space","volume":"34","author":"Dai","year":"2015","journal-title":"Chinese Journal of Acoustics"},{"issue":"4","key":"10.3233\/JCM-215155_ref9","first-page":"351","article-title":"A detecting method for line-spectrum target by fusing output DC jump to fluctuations ratio of sub-band spatial spectrum and beam space","volume":"71","author":"Dai","year":"2010","journal-title":"Applied Acoustics"},{"key":"10.3233\/JCM-215155_ref10","unstructured":"W.
