The January/February 2021 issue of Acoustics Bulletin will be with members shortly and it includes:

  • Dr Peter Mapp’s study on the acoustic and communication effects of face masks. We’ve all become accustomed to wearing them, but they make life for deaf and hard of hearing people very difficult. Peter specialises in the field of speech intelligibility and has measured the speech attenuation properties of more than 20 face masks to see what they were actually doing.
  • We publish details of the 2020 IOA Diploma results; the COVID pandemic made it impossible to hold written examinations at centres in 2020, so arrangements were made for examinations to be downloaded ‘at home’ and for the written answers to be scanned and submitted online. This made the examinations essentially ‘open book’ with the result that fewer candidates have failed than has been typical.
  • The lack of road traffic and transport noise led to markedly lower noise levels in the general environment at times last year. The Instrumentation Corner article focuses on whether assessment of that noise during lockdowns is producing appropriately robust impact assessments.
  • Results of the Early Careers Group member survey and the recent changes at the group.
  • Last December, the EAA resolved to publish the Acta Acustica archive (1996-2019) to allow free access to its member institutes (including the IOA) returning the previously interrupted service to its members. A project is now underway to allow this publication with the hope that the archive will again be fully available to all EAA members by this spring.  
  • Profiles of two successful recent Engineering Council candidates; Edward Elbourne and Richard Muir.

The deadline for the next issue (March/April 2021) issue is Monday 8th February 2021 at the latest please. If you have a technical article that you’d like to submit for consideration, please email the editor at nickyr [at] warnersgroup [dot] co [dot] uk
