Research on the Sound Insulation Properties of Membrane-type Acoustic Metamaterials [PDF]
E3S Web of Conferences, 2021 Low- and medium-frequency noise from ship cabins is difficult to control effectively. Excessive noise can seriously affect the acoustic stealth performance of ships. A novel membrane-type acoustic metamaterial is proposed in this paper with light weight and good sound insulation performance at low frequencies.

Sound insulation properties of a spherical structure of subwavelength size [PDF]
AIP Advances, 2019 Because of the limited sound insulation provided by a single material, it is common to use multiple layers of materials to improve the effects of sound insulation, but multiple materials increase the size of the model. In some cases, there are limits to the size of the model, or, if subwavelength sizes are required, it is necessary to investigate ...

Sound Insulating Properties of Certain Building Materials [PDF]
The Journal of the Acoustical Society of America, 1935 Transmission loss data obtained in the Johns-Manville Laboratories on various building constructions are reported. Almost all this data has been obtained on “room size” floors and partitions. The relation between such tests and “panel” tests is given where data is available.
