Title: | Noise control zone for a periodic ducted Helmholtz resonator system | Authors: | Cai, C Mak, CM |
Issue Date: | Dec-2016 | Source: | Journal of the Acoustical Society of America, Dec. 2016, v. 140, no. 6, p. EL471-EL477 | Abstract: | This paper presents a theoretical study of the dispersion characteristics of sound wave propagation in a periodic ducted Helmholtz resonator (HR) system. The predicted result fits well with a numerical simulation using a finite element method. This study indicates that for the same system, no matter how many HRs are connected or what the periodic distance is, the area under average transmission loss T L curves is always the same. The broader the noise attenuation band, the lower the peak attenuation amplitude. A noise control zone compromising the attenuation bandwidth or peak amplitude is proposed for noise control optimization. | Publisher: | Acoustical Society of America | Journal: | Journal of the Acoustical Society of America | ISSN: | 0001-4966 | EISSN: | 1520-8524 | DOI: | 10.1121/1.4968530 | Rights: | Copyright 2016 Acoustical Society of America.
