Clean Audio for TV broadcast: An Object-Based Approach for Hearing-Impaired ViewersMay 18, 2015
Update: I just uploaded a new journal article published last month in the Journal of the Audio Engineering Society. Happily the University of Salford paid for it to be open access as part of their open access strategy so it’s freely available for anyone to download.
The paper (right) is a follow up to my PhD research, which was all about looking at methods to improve TV sound for people with hearing impairments by enabling what is usually known as ‘clean audio’ – helping hearing impaired people to hear speech more clearly than is often the case.
The early part of the PhD was funded by the ITC and then Ofcom, later parts were carried out as part of the EU funded FascinatE project which I’ve written about on this blog before. The FascinatE project utilised what is known as object-based audio to implement interactive 3D (with height) spatial audio which would vary depending on the user-defined visual scene. The FascinatE viewer could have free navigation of the visual scene and point their ‘camera’ to whatever part of the video panorama was of interest to them. The audio ‘objects’ rotated and/or moved to match the chosen view.
In the more recent clean audio work above Rob Oldfield and I have been extending some of the work we did in FascinatE and are using object-based audio to personalise TV audio to whatever mix best suits a person’s hearing impairment. We have some other experimental work planned and the S3A project, which I am also working on, is looking into object-based spatial audio and potential benefits for people with hearing impairments as well so expect more in this vein over the next few months/years. Meanwhile you can download the article from the picture over to the right or visit my publications page here where most of my other papers are also freely available.
