论文摘要
尽管在几个国家使用声音出现来调节风能开发，但没有公开的证据表明，它是为此目的的相关噪声描述。在目前的工作中，我们进行了两项听力测试，以评估声音出现的优点。考虑了声音出现的三个定义：ISO 1996-1中的一个定义，在听觉条件下的声音出现$ e_ {uac} $和频谱出现$ e_ {sp} $。我们还考虑了特定于残余比率和响度指标。在每个听力测试中，声音刺激由3个加权的声音压力水平$ \ {30、40、50 \} $ 〜DB和4个特定与剩余比率组成的48个声刺激$ \ { - 10、5、0、0、0，+5 \} $ 〜db。结果得出的结论是，总的声压水平比声音出现更好地预测了短期的烦恼，无论是在后者考虑的定义，而不是特定于剩余比率。 $ e_ {uac} $比$ e $预测的短期烦恼稍好，而$ e $比$ e_ {sp} $更好。总声压水平和响度指标的性能相似。此外，结果提供了证据表明，声音出现是风力涡轮机声音可听性的差的不良预测指标。
While sound emergence is used in several countries to regulate wind energy development, there is no published evidence that it is a relevant noise descriptor for this purpose. In the present work, we carried out two listening tests to evaluate the merits of sound emergence. Three definitions of sound emergence were considered: the one in ISO 1996-1, sound emergence under audibility condition $e_{UAC}$, and spectral emergence $e_{SP}$. We also considered the specific to residual ratio and loudness metrics. In each listening test, the sound stimuli consisted of 48 sound stimuli at 3 A-weighted sound pressure levels $\{30, 40, 50\}$~dB and 4 specific-to-residual ratios $\{-10, -5, 0, +5 \}$~dB. The results lead to the conclusion that short term annoyance is better predicted by the total sound pressure level than by sound emergence, whatever the definition considered for the latter, or than by the specific to residual ratio. Short-term annoyance is slightly better predicted by $e_{UAC}$ than by $e$, while $e$ is a better predictor than $e_{SP}$. The total sound pressure level and the loudness metrics performed similarly. Furthermore, the results provide evidence that sound emergence is a poor predictor of the audibility of wind turbine sounds.
