Abstract
Finite element modelling (FEM) has become the industry standard for simulating and developing acoustic transducers. One valuable application of FEM is the ability to predict transducer performance prior to prototyping. However, the accuracy of these simulations depends heavily on derived material parameters, which are typically obtained using the Obrest method—a manual, equipment-intensive process. This presentation covers an alternative approach for estimating Young’s modulus and damping ratio using standard testing equipment commonly available in transducer development centres. Materials are experimentally evaluated, and their measured properties are used in FEM simulations. The resulting models are then compared to physical counterparts to validate the method’s accuracy.
The talk will be followed by a short Q&A session.
Bio
Jacek Majewski is an Acoustic Engineer Intern at Tymphany Acoustic Technology, where he specializes in transducer simulation and hardware prototyping. He is currently pursuing an MSc through the International Master's Degree in ElectroAcoustics at Le Mans Université, alongside holding a BEng in Acoustic Engineering from Solent University. His work focuses on the integration of finite element simulation and the optimization of loudspeaker components, with the goal of improving performance prediction and reducing development time. He will present his recent work on accessible methods for evaluating material parameters to enhance the accuracy of transducer modelling.
