Dr Haydar Aygun

I am an Associate Professor in Acoustics and Building Services, and the Course Director for MSc Environmental and Architectural Acoustics, Diploma in Acoustics and Noise Control, and The Acoustics Apprenticeship. I obtained my PhD degree in Acoustics and Vibration from the University of Hull in 2006. I have a MSc in Advanced Materials, Processes and Manufacturing from the University of Hull in 2002 and a BSc in Mechanical Engineering.  
I am an expert in acoustic materials, physical acoustics, environmental noise, building acoustics, noise and vibration control, ventilation and air conditioning, and biomedical acoustics. I worked as a researcher in acoustics at the University of Hull. I have successfully completed several funded research projects both there and at Katholieke Universiteit Leuven.

My research interests include:
Materials: Developing and characterising novel materials (sound absorbing materials, noise barriers, composite panels) to solve noise and vibration problems caused by different applications.
Duct Acoustics: I have investigated aerodynamic and acoustic properties of sound propagation through circular and rectangular ducts, testing a range of sound absorbing materials/plates mounted in the duct, calibrating duct systems, determining air flow chart for the duct systems.
Design and development of devices: I have developed and tested several acoustic devices to investigate the acoustical properties of materials.
CFD (Computational Fluid Dynamics) & FEM (Finite Element Analysis): Simulated acoustic waves in an impedance tube used in combustion engines, and Used FEM to determine structural properties of materials
Biomedical Acoustics: Investigation of acoustical properties of the bone using a novel vibro-acoustic model; developed a vibro-acoustic model to determine structural parameters of the rigid porous materials (bone); Investigation of bone parameters that are effecting sound propagation through it using ultrasound and Biot theory. I have investigated the reliability of the stethoscopes to detect tracheal sounds for determining lung related problems, and I am working on novel methods to detect lung/mouth/tracheal sounds.

Vibration: Investigating the theory of porous and non-porous plates and membranes.

Currently, I am co-supervising three PhD projects ranging from acoustic mate-materials, sound propagation through plastic duct systems, and detecting osteoporosis using vibro-acoustic methods.
I formed a Biomedical Acoustic Special Interest Group (BA SIG) as part UK Acoustics Network to establish links between biomedical researchers and the rest of UK acoustics community, and more widely with the international biomedical acoustics community. I am deputy leader of Biomedical Acoustics SIG.
I have undertaken consultancy work including impact noise assessment, road traffic noise, building sound insulation, determination of sound pressure levels emitted by control panels under vibration, measuring the absorption and transmission loss of porous materials, monitoring noise at festival and noise mapping of events.
I am an Editorial Board Member for Journal of Applied Acoustics. I am a EPSRC Grant Reviewer, and a reviewer for Journal of Applied Acoustics, and Journal of the Acoustical Society of America. I have organised and chaired webinars and workshops, and also chaired some conference session at acoustics conferences.
I have supervised several PhD students and research assistants.
We offer PhD programs in acoustic materials, metamaterials, noise and vibration control, thermo-acoustics, biomedical acoustics, building acoustics, smart acoustic systems with machine learning and AI, and in thermo-acoustic properties of buildings.
