矿棉吸声体吸声特性的研究陆风华，李竹园，郑渝（太原工业大学）一、引言随着噪声控制技术的迅速发展，空间吸声体已得到日益广泛的应用。空间吸声体是一种悬挂于室内的高效吸声结构，由于它各界面全部暴露在声场空间，增大了与声波的接触机率，所以有较明显的吸声效果。... Study on Sound Absorption Properties of Mineral Absorbers in Minzhu Lu Fenghua, Li Zhuyuan, Zheng Wei (Taiyuan Institute of Technology) I. INTRODUCTION With the rapid development of noise control technology, space acoustic absorbers have been increasingly used. The space sound absorber is an efficient sound-absorbing structure suspended in the room. Since all of its interfaces are exposed in the sound field space, the contact probability with the sound wave is increased, so that the sound absorption effect is more obvious. ...
