Noise pollution is a serious problem in many aspects of modern society. Although many materials exist that can provide mechanisms for sound absorption, particularly in the higher frequency ranges, compact low-frequency noise attenuation and absorption remains a significant challenge. It is therefore becoming increasingly important to design improved materials that can be employed in low-frequency noise control scenarios.
Recently, a new class of materials known as nano-fibre composites have been shown experimentally to offer excellent sound absorption characteristics at low frequencies. However the mechanisms by which they provide this enhanced acoustic absorption are not clearly understood and existing models fail to adequately describe this behaviour.
This project will therefore develop mathematical models of acoustic propagation in nano-fibre composites with the objective of improving the understanding of the mechanisms of sound absorption in such media.
This project is a collaboration between the School of Mathematics at the University of Manchester and Dyson Technology Ltd. The student will be expected to spend time at the industrial collaborator and work with them to validate theoretical results experimentally.
Candidates with a strong background in applied mathematics and/or physics, with excellent theoretical and technical ability and a strong motivation and enthusiasm for interdisciplinary scientific research are encouraged to apply. The successful applicant should have a high first class honours degree and ideally a related Masters degree and be available to start in September 2018 or shortly after. Applications should include a cover letter (two pages maximum) describing background and motivation and a complete CV (two pages maximum). These will be considered upon receipt and the position will remain open until filled.
Informal queries should be emailed to Prof. William J. Parnell (firstname.lastname@example.org)
