Abstract:

That water noise can mitigate the perception of traffic noise, is well documented in the literature, mostly on the basis of laboratory studies. For the "Cercle Bruit" (Association of Swiss Noise Abatement Authorities), we assessed several practical situations, documented them in binaural sound recordings and derived guidelines on how wells and fountains or creeks and rivers can be designed to optimize this effect.Water noise may a) reduce the dynamic range of traffic noise and thus its conspicuousness, partially filling in noise breaks; b) mask (partially) the traffic noise, which is perceived as a relief despite the higher overall sound level; c) draw attention away from traffic noise to the more interesting water noise (if this is diverse and/or variable over time); d) "reinterpret" traffic noise (if it comes from the same direction and is spectrally similar), because the traffic noise is assigned to the river or well and subsequently assessed as positive.In general, water sounds have more effect against broadband rolling noise, but less so against tonal engine noise. With increasing electromobility, however, engine noise should decrease, while rolling noise will remain. The chances that water noise mitigates the annoyance due to traffic noise could therefore improve.
