虽然当代研究人员担心青少年和年轻人经常喜欢长时间听高水平音乐的便携式听音设备（PLD）过度使用，但这些研究中的许多研究都集中在比较各种耳机的声压水平或通过调查评估对噪声听力损失和听力习惯的识别。此外，当前的标准是针对职业性噪音引起的听力损失制定的，因此针对娱乐性噪音暴露引起的听力损伤只有少数已发布的指南。本研究，因此，测量实际的听力水平和PLD时间在大学生使用实时测量系统，并应用收集的科学数据，国际推荐的噪声暴露标准。34名大学生被要求听4周类似于他们日常生活方式的音乐。安装应用程序后，链接到用户移动的手机的Google帐户登录到服务器通信。当受试者听音乐时，平均和最大听力水平以及听力时间可以被识别为他或她的Google帐户ID，并存储在数据库中进行分析。用户数据每隔1秒测量一次，每隔5秒发送到主服务器系统。将数据分析为平均水平的LZeq和最大水平的LCpeak，以及PLD使用时间。平均听力水平为68 - 70 dB SPL，持续4周，并有足够长的休息时间。也就是说，大学生的听力水平不高，不足以导致即时听力损失时，他们使用PLD。然而，有一个很大的个人差异的听力水平和使用时间。当应用到三个推荐的噪声暴露标准，超过主题的数量也不同，从0到56.72%，这取决于标准。因此，我们建议，音乐引起的听力损失的适当和标准化的标准可能会提出娱乐PLD用户。
Although contemporary researchers are concerned about overexposure of portable listening devices (PLD) for adolescents and young adults who often prefer listening to music at high levels for a long time, many of these studies have focused on either comparing sound pressure levels of various kinds of earphones or evaluating the recognition of noise-included hearing loss and listening habits through surveys. Further still, current criteria were developed for occupational noise-induced hearing loss, so there are only a few published guidelines for hearing insults due to recreational noise exposure. The present study, therefore, measures actual listening levels and PLD time in college students using a real-time measurement system and applying that gathered scientific data to the internationally recommended noise exposure standards. Thirty-four college students were asked to listen to music similar to their daily lifestyles for 4-weeks. After installing the application, the Google account that linked to the user’s mobile phone was logged into the server communication. When a subject listened to music, the average and maximum listening levels and listening time could then be recognized as his or her Google account ID and stored in the database for analysis. User data was measured at 1-s intervals and delivered to the main server system every 5 s. The data were analyzed as LZeq for mean levels and LCpeak for maximum levels, and also for PLD use time. The mean of the preferred listening level was 68–70 dB SPL for 4 weeks with long enough break times. That is, the listening levels of college students were not high enough to induce instant hearing loss when they used PLD. However, there was a large individual difference in the listening levels and use times. When applied to three recommended noise exposure criteria, the number of exceeded subjects also differed from 0 to 56.72% depending on the criterion. We thus suggest that appropriate and standardized criteria for music-induced hearing loss might be proposed for recreational PLD users.
