摘要
了解室内低频噪声的分布及对受声者的烦恼度的影响。对形成室内低频噪声的重要因素———家用电器噪声进行声源特性测试,对受声者的烦恼度进行问卷调查,并利用模糊数学的方法对室内低频噪声的烦恼度进行分析。结果表明:家用电器噪声是明显的中低频噪声,使受声者产生较强的烦恼度,而通过绿色盆栽进行室内绿化并对室内低频噪声源进行遮挡后,受声者对低频噪声的烦恼度有较明显的降低。
The possibility of low-frequency noise existed indoor and the influence of annoyance of indoor low-frequency noise were studied. The Survey of indoor low-frequency noise frequency spectrum characteristic, the investigation of subjective response to indoor low-frequency noise and analytic calculation with principle of fuzzy subordinate grade were made. The results indicaed that the noise of electric appliance was low-frequency noise, people had less noise annoyance when the sources of indoor low-frequency noise hide behind the potted plant than they were visible. People have less noise annoyance when the sources of indoor low-frequency noise hide behind the potted plant. [Ch, 2 tab. 9 ref. ]
