Abstract: (816 Views)
An understanding of both the areas of materials science and acoustics is necessary to successfully develop materials for acoustic absorption applications (code 3). This paper investigates the acoustic absorption behavior Hollow Carbon Nanospheres (HCNSs). Sound absorber sample from HCNSs are fabricated and their acoustic properties are investigated through experiment. Tests were conducted using an impedance tube to measure the acoustic absorption coefficient of the HCNSs. Good acoustic absorption performance is observed at 4500−6500 Hz with average absorption coefficient of 31% which is comparable with other nanomaterial absorbers such as CNTs. The outcomes of this investigation highlight the potential of the HCNSs for use as light-weight acoustic absorbers.
