- A field experiment was conducted to explore whether water sounds from a fountain had a positive impact on soundscape quality in a downtown park. In total, 405 visitors were recruited to answer a questionnaire on how they perceived the park, including its acoustic environment. Meanwhile the fountain was turned on or off, at irregular hours. Water sounds from the fountain were not directly associated with ratings of soundscape quality. Rather, the predictors of soundscape quality were the variables “Road-traffic noise” and “Other natural sounds”. The former had a negative and the latter a positive impact. However, water sounds may have had an indirect impact on soundscape quality by affecting the audibility of road-traffic and natural sounds. The present results, obtained in situ, agree with previous results in soundscape research that the sounds perceived—particularly roadtraffic and natural sounds—explain soundscape quality. They also agree with the results from laboratory studies that water sounds may mask road-traffic sounds, but that this is not simple and straight forward. Thus sound should be brought into the design scheme when introducing water features in urban open spaces, and their environmental impact must be thoroughly assessed empirically.

- This paper will discuss the use of psychoacoustic evaluation as a tool for optimization of the soundscape simulator developed in the Listen project. The listen project is a three-year research project focused around developing a demonstrator, which auralizes the sound environment produced by road and railway traffic. The resolution of the parameter space of the simulator heavily influences the performance of the simulator. The perceptual resolution of the parameter space is investigated and the resolution is adjusted accordingly. The most important parameter is velocity. Adjustments of the resolution of this parameter alone gives a 60% reduction of the usage of memory.
