The purpose of this study was to evaluate the possible effects of risk factors on distortion product otoacoustic emissions (DPOAEs) in young adult men with normal hearing. Four hundred thirty-six United States Marine recruit men (mean age = 19.2 years +/- 1.8 years; age range = 17-29 years) participated in this study. Questionnaires were given to each recruit to obtain demographic data and history of noise exposure, solvent exposure, smoking history, and hearing-related histories. Otoscopy, tympanometry, pure-tone air-conduction audiometry (2.0-8.0 kHz) and DPOAEs (2.3-8.0 kHz) were measured. DPOAE levels were lower in Not Hispanic or Latino recruits, in heavy smokers, in recruits who reported loud live music exposure and ringing in their ears after noise exposure. These differences were not statistically significant at all frequencies. Recruits with multiple risk factors had the lowest DPOAEs as compared to recruits with fewer, or no, risk factors; these differences were not statistically significant. Obtaining risk factor data as part of an audiometric evaluation is important even though the individual may have normal hearing.
本研究的目的是评估危险因素对听力正常的年轻成年男性畸变产物耳声发射（DPOAE）的可能影响。436名美国海军陆战队新兵（平均年龄 = 19.2岁±1.8岁；年龄范围 = 17 - 29岁）参与了本研究。向每位新兵发放问卷以获取人口统计学数据以及噪声暴露史、溶剂暴露史、吸烟史和听力相关病史。进行了耳镜检查、鼓室导抗图测量、纯音气导听力测定（2.0 - 8.0 kHz）和DPOAE测量（2.3 - 8.0 kHz）。非西班牙裔或拉丁裔新兵、重度吸烟者、报告有现场大声音乐暴露以及噪声暴露后耳鸣的新兵，其DPOAE水平较低。这些差异在所有频率上均无统计学意义。与具有较少或无危险因素的新兵相比，具有多种危险因素的新兵DPOAE最低；这些差异无统计学意义。即使个体听力正常，获取危险因素数据作为听力评估的一部分也很重要。
