Salford Acoustics Research and Arup co-host workshop on the use of numerical modelling and auralisation in built environment design

4 September 2015
Arup SoundLab Manchester

The SoundLab at Arup’s Manchester Office

Prof Yiu Lam and Dr Jonathan Hargreaves have been working for the last three years in collaboration with Steve Langdon at the University of Reading and industrial partners Arup and the BBC on an EPSRC funded project developing new computational acoustic algorithms aimed at auralisation applications.  As a culmination of this, they are organising a two day workshop to discuss the latest developments, and future research challenges and priorities, in this field, and specifically its application to built environment design consultation. The workshop will be hosted by Arup at their Manchester office, and will make use of their renowned SoundLab facility for audio demos.

Dr Jonathan Hargreaves represents Salford at EU research workshop in Freising

MHiVec project logoMHiVec is an EU FP7 IAPP project which is applying a new modelling method called Dynamic Energy Analysis (DEA) to structural and acoustic modelling of vehicle NVH at mid-to-high frequencies. This method works by transferring distributions of directional wave energy between elements of a discretised mesh of a sub-system boundary, be that an acoustic cavity or a structural element (e.g. a metal plate) and then solving for the steady-state intensities. It therefore has much in common with some late-time acoustic reverberation models and SEA but, like SEA, can be applied to a wider class of vibrating systems.

The MHiVec team organised a workshop in Freising, Germany, at the start of September 2015. Dr Jonathan Hargreaves from the ARC was an invited speaker and gave a talk on synergies between BEM and beam-tracing methods. In return, we are lucky to have MHiVec PI Dr David Chappell from NTU attending and presenting at the computational acoustics and auralisation workshop we are organising in collaboration with Arup on the 22nd and 23rd September, where he will speak on the application of DEA to room acoustics in 3D.

Spatial audio conference paper selected for inclusion in journal special issue

Dr Jonathan Hargreaves represented the Acoustics Research Centre at the EAA Joint Symposium on Auralization and Ambisonics in Berlin today, with his presentation entitled ‘An energy interpretation of the Kirchhoff-Helmholtz boundary integral equation and its application to Sound Field synthesis’. This included some new orthogonality relations for spherical harmonic waves, which have potential applications in spatial audio rendering and high-order microphone array design. Jonathan was delighted to hear that the paper had been selected as one of the 10 best in the conference, and will be included in a special issue of Acta Acustica United with Acustica later in the year.
