Objective To reinforce the management of campus noise and improve students' learning ability by examiningthe effects of different noise levels on college students' attention.
Methods College students (n=300) were divided into fivenoise groups randomly:50,60,70,80,90 dB (A),and background noise level as control group,gender ratio 1:1.The attention wasmeasured by an attention test scale and the decible value of noise by a sound level meter.
Results The results of students' comprehensive attention and attention transfer ability were lower in the five noise groups than in the control group (P<0.05),andwere 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 attentionspan and attention distribution were lower in the 80dB (A) and 90dB (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 affectstudents'attention,especially noise levels at 80 dB (A) and above.
