Perceptual assessment of indoor water sounds over environmental noise through windows

摘要

Indoor water sounds were examined in terms of perceptual enhancement of environmental noise through openings for natural ventilation. An experiment was conducted using a simple indoor water fountain system with forty participants (18 women and 22 men) aged between 19 and 27 in an environmental chamber. The indoor water sound levels were varied from 35.8 dBA to 59.8 dBA. Environmental noises transmitted through windows in the living rooms of actual residences were measured and classified into traffic and railway noises and their levels were between 43.0 dBA and 62.1 dBA.
