摘  要:[目的]研究不同强度噪声对大学生注意力的影响,为进一步加强校园噪声的管理,提高大学生学习能力提供科学依据。[方法]随机选取300名各专业大学生按男女1∶1的比例分为50、60、70、80、90 dB(A)噪声组和1个对照组,利用注意力测试量表测定注意力,声级计测定噪声。[结果]5个噪声组的综合注意力及注意力转移均低于对照组(P<0.05)。在噪声组中80、90 dB(A)组综合注意力低于50、60 dB(A)组(P<0.05);80、90 dB(A)组注意力广度和注意力分配均低于对照组及50、60、70 dB(A)组(P<0.05);90 dB(A)组注意力稳定性低于对照组和50、60、70、80 dB(A)组(P<0.05)。各组间男女生注意力比较,差异无统计学意义(P>0.05)。[结论]50 dB(A)及以上的噪声就可以对大学生注意力产生影响,80 dB(A)以上影响明显。[Objective] To reinforce the management of campus noise and improve students’ learning ability by exploring the effects of different noise levels on college students’ attention. [Methods] College students (n=300) were divided into five noise groups randomly: 50, 60, 70, 80, 90 dB (A), and background noise level as control group, gender ratio 1 : 1. The attention was measured by an attention test scale and the decible value of noise by a sound level meter. [Results] The results of students’ comprehensive attention and the attention transfer ability were lower in the five noise groups than in the control group (P 〈 0.05) and much lower in the 80 dB(A) and 90 dB(A) groups than in the 50 dB(A) and 60 dB(A) groups (P 〈 0.05). The results of attention span and attention distribution were lower in the 80 dB(A) and 90 dB(A) groups than in the 50 dB(A), 60 dB(A), and 70 dB(A) groups (P 〈 0.05). The 90 dB(A) group was lower than the control group and the other four noise groups in the attention stability results (P 〈 0.05). No gender difference was found in the attention evaluation (P 〉 0.05). [Conclusion] Noise levels at 50 dB(A) and above can affect students’ attention, especially noise levels at 80 dB(A) and above.
