Absorption of oblique incidence sound by a finite micro-perforated panel absorber.
In this paper, a theoretical model of a micro-perforated panel (MPP) backed by a finite cavity and flush-mounted in an infinite baffle is developed and its performance in terms of sound absorption is analyzed. The model allows an oblique incidence sound impinging upon the MPP absorber. The simplified Rayleigh integral method, thin plate theory and the acoustical impedance of the MPP are used to...
متن کاملStudy of the effect of shape on acoustic performance of micro perforated absorbent at low frequencies
Introduction: Micro-perforated absorbents are one of the structures that are widely used nowadays. The sound absorption mechanism is performed by viscous energy losses in the cavities on the plate. In this study, the acoustic properties of non-flat perforated panels in oblique angle was investigated in numerical method. Material and Methods: This paper examined the effect of the surface shape ...
متن کاملSound attenuation using duct silencers with micro-perforated panel absorbers
Micro-perforated panel (MPP) can be used as non-fibrous acoustic absorber which can provide broadband sound absorption performance. In this study, a sub-structuring methodology based on the Patch Transfer Function (PTF) approach to deal with duct silencers with MPP absorbers and internal partitions is proposed, and the sound attenuation performance of such silencers is investigated. Reactive si...
متن کاملStudy of a compact energy absorber
Deformable energy absorbers play a vital role in crash protection systems. However, prevailing stringent design requirements to mitigate impact damage in a limited space have advocated a need for superior energy absorbing materials and versatile and compact structures. In this thesis, an intelligent compact energy absorbing structure is presented that alleviates the impact by distributing load ...
متن کاملAcoustic properties of 3D printed bio-degradable micro-perforated panels made of Corkwood Fiber-Reinforced composites
Introduction: Micro perforated panel (MPP) absorbents promise the next generation of sound absorbers as they have significant advantages over other porous adsorbents. In this study, we will investigate the acoustic performance of MPP absorbents made of biodegradable polylactic acid composite reinforced with natural corkwood fibers (PLA/Corkwood) by 3D printing technology. Material and Methods:...
