Daniel de la Prida from Carlos III University in Madrid presented about his study into listening tests. He focussed on tests that can be used for linking objective room acoustic parameters with subjective human perception.
Such tests have been in use for many years. However, different research usually employs different test protocols, with different operational powers and robustness. Thus, results can be very divergent and incomparable.
Linking acoustic measurements with subjective human perception
Daniel presented the results of his listening test based on several test protocols. These are commonly used in room acoustics, and in other areas of sensory perception. The aim of research was to compare operational power of these different methods.
The listening test Protocols
The Protocol has a significant influence on:
- The way of presenting the stimuli
- The query method used to capture the participants’ answers.
- The applicable analysis methods.
He points out that we can be very precise with acoustic measurements and the difference in data is clear and understood. However, how we sense and feel acoustic differences is complex. We lack research, unlike the vast research and knowledge which has been undertaken about our sense of and perception of difference in taste.
