Objective The purpose of this paper is to verify the different noise isolation effects of different types of entertainment headphones and to analyze the potential hearing loss risks of people using entertainment headphones in different noisy environments so as to provide suggestions for public hearing health protection. Methods To compare the volume setting preferences and speech recognition scores(SRS) in noise in 36 college students who wore earbuds, headphones and inserted earphones respectively in quiet conditions(30 dB(A)), 65 dB(A) and 75 dB(A) noise conditions. Results The effect of different noise environment on the volume setting preference and SRS of entertainment headphones was significant(P0.01). In quiet environments(30 dB(A)), headphone got a higher setting volume and a lower SRS than the other two types, while in 65 dB(A) and 75 dB(A) noise conditions, the volume settings of earbuds were the lowest. Also, the SRS difference of the three types is significant(P0.01). Conclusions In noise environments, the sequence of noise isolation effect is earbuds inserted headphones headphones, so earbuds' excellent noise isolation effect entitles them to the advantage of protecting hearing to some extent. However, no matter what types of headphones, we should reduce the time to use headphones in noise environment, especially on the underground.
