‘Tea and talks’ event for study participants, 28 April 2017

All older participants in the speech production study carried out as part of our current ESRC-funded project were invited back for an afternoon of ‘tea and talks’ organised by Outi Tuomainen. The aim of this event was to give participants a brief review of the main findings of our study. These were presented by Outi. The event also included short talks by Professor Stuart Rosen on the challenges of perceiving speech in noisy environments and by Dr Tim Schoof on hearing aids. Around 35 participants as well as representatives of the University of the Third Age (U3A) and Action for Hearing Loss attended the event. The talks were followed by tea and cakes, with an opportunity for more informal chats with researchers.

A collaboration between speech scientists Outi Tuomainen and Valerie Hazan  and sound artist Thor McIntyre-Burnie (ASWARM) resulted in the creation of a sound installation entitled Clang Bang Swoosh Boom which was exhibited at the Bloomsbury Festival as part of the Beyond Words day of events based at UCL. Our installation aimed to focus attention on how we adapt our speech to communicate effectively in an increasingly noisy world. It also highlighted how noisy environments particularly affect communication in children and older adults.

Getting the final touches right on the Clang Bang Swoosh Boom installation

The sound materials used in the installation were extracted from the speech corpora collected within our ESRC-funded projects on speech communication in adverse conditions in children and adults. Each of four audio channels within the installation played the voice of either a child, young or older adult. In our speech corpora, they had been recorded while carrying out the diapix task and describing the same picture to their conversational partner who was hearing distorted speech. Further audio channels were added that periodically added environmental noises or other voices emanating from some of the objects in the installation.

In the example above, you can hear all four voices mixed together;  in the sound installation itself, each voice was heard through one of the horns, additional voices came through transducers placed under the white seats, and environmental sounds were played out of two further speakers. The spatial separation enabled members of the public to walk around the installation in order to tune into one particular voice as well as to sit in the white seats and get the full sensation of hearing multiple voices and noises coming from the 6 speakers as well as the seats themselves! The pictures from the diapix ‘spot the difference’ task used in the recordings were around the room and audience members were invited to guess which picture the four voices were describing. Beyond Words was attended by several thousand people and a steady stream of members of the public of all ages came to experience our sound installation. Outi, Valerie and Thor were on hand to discuss the work and the science behind it with the audience. A leaflet describing ‘The Science behind Clang Bang Swoosh Boom‘, with a short biography of members of our team was also distributed.
