Acceptable noise level (ANL) is a measure of the maximum background noise level (BNL) that a person is willing to tolerate while following a target story. Although researchers have used various sources of target sound in ANL measures, a limited type of background noise has been used. Extending the previous study of Gordon-Hickey & Moore (2007), the current study determined the effect of music genre and tempo on ANLs as possible factors affecting ANLs. We also investigated the relationships between individual ANLs and the familiarity of music samples and between music ANLs and subjective preference.
Forty-one participants were seperated into two groups according to their ANLs, 29 low-ANL listeners and 12 high-ANL listeners. Using Korean ANL material, the individual ANLs were measured based on the listeners' most comfortable listening level and BNL. The ANLs were measured in six conditions, with different music tempo (fast, slow) and genre (K-pop, pop, classical) in a counterbalanced order.
Overall, ANLs did not differ by the tempo of background music, but music genre significantly affected individual ANLs. We observed relatively higher ANLs with K-pop music and relatively lower ANLs with classical music. This tendency was similar in both low-ANL and high-ANL groups. However, the subjective ratings of music familiarity and preference affected ANLs differently for low-ANL and high-ANL groups. In contrast to the low-ANL listeners, the ANLs of the high-ANL listeners were significantly affected by music familiarity and preference.
The genre of background music affected ANLs obtained using background music. The degree of music familiarity and preference appears to be associated with individual susceptibility to background music only for listeners who are greatly annoyed by background noise (high-ANL listeners).
可接受噪声水平（ANL）是指一个人在收听目标故事时愿意容忍的最大背景噪声水平（BNL）。尽管研究人员在ANL测量中使用了各种目标声音来源，但背景噪声的类型却较为有限。在扩展了戈登 - 希基和摩尔（2007年）的先前研究的基础上，本研究确定了音乐流派和节奏对ANL的影响，将其作为可能影响ANL的因素。我们还研究了个体ANL与音乐样本熟悉度之间以及音乐ANL与主观偏好之间的关系。
41名参与者根据其ANL分为两组，29名低ANL听众和12名高ANL听众。使用韩国ANL材料，根据听众最舒适的收听水平和BNL测量个体ANL。在六种条件下测量ANL，背景音乐的节奏（快、慢）和流派（韩国流行音乐、流行音乐、古典音乐）以平衡顺序变化。
总体而言，背景音乐的节奏对ANL没有影响，但音乐流派显著影响个体ANL。我们观察到韩国流行音乐的ANL相对较高，古典音乐的ANL相对较低。这种趋势在低ANL组和高ANL组中都相似。然而，音乐熟悉度和偏好的主观评分对低ANL组和高ANL组的ANL影响不同。与低ANL听众不同，高ANL听众的ANL受音乐熟悉度和偏好的显著影响。
背景音乐的流派影响了使用背景音乐获得的ANL。音乐熟悉度和偏好程度似乎仅与那些对背景噪声非常敏感的听众（高ANL听众）对背景音乐的个体易感性相关。
