The aim of this project is to investigate the indoor noise levels from external sources (such as road traffic) that may be acceptable to occupants on a short term basis when the alleviation of overheating is required. This is a collaborative, interdisciplinary proposal exploiting two unique world-class sets of experimental facilities and expertise at the University of Salford: the Acoustics Test Labs and the Energy House Labs.
There is currently insufficient guidance regarding indoor ambient noise levels that should be achieved in residential developments in the situation where measures are required to control overheating. This lack of guidance is resulting in new residential developments with poor indoor environmental conditions where residents are not able to achieve thermal and acoustic comfort at the same time. The problem is exacerbated by the move towards better insulated, more airtight buildings and the need, particularly in urban areas, to consider development on noisier sites. It seems very likely that this is giving rise to unnecessary sleep disturbance and adverse health effects in an increasing population of people, and reduced productivity given the recent sharp rise in home working.
There is therefore a need to develop optimal solutions for noise and ventilation in residential developments. A starting and important step to achieve optimisation is to study the human response to and inter-dependence of acoustic and thermal comfort in dwellings. This can be achieved using lab studies on relatively small groups under closely controlled conditions; exclusive facilities that Salford is able to provide.
This requires determination of three independent factors:
- Physiological response: determined using measurements such as galvonic skin response, heart rate, and salivary cortisol.
- Affective transfer: how the subjective rating of the noise stimulus changes due to changes in ventilation, determined using questionnaires and interview.
- Cognitive impact: the negative effect on task performance, attention and memory, investigated using psychology techniques previously applied in open-plan office research.
Candidates will need a 1st class or high 2:1 honours degree in a relevant subject.
