The purpose of this study was to evaluate the auditory life styles and beliefs of college students with reference to exposure to loud sounds in the context of the health belief model. A survey was administered to 238 (40 men, 198 women) students in the USA. Results suggest that 44% of the students use noisy equipment without ear protection and 29% (69/238) of the students work in noisy environments. Of the 69 who worked in noisy surroundings, only ten reported wearing hearing protection devices although 50 (72.46%) reported tinnitus. The use of hearing protection devices (HPDs) was associated with previous experience with hearing loss and tinnitus. Although 75% of the students were aware that exposure to loud sounds could cause hearing loss, 50% of the students appeared to be exposing themselves to potentially harmful loud music. Furthermore, 46% of the students reported not using HPDs during loud musical activities because they felt that the music was difficult to hear with HPDs. Most students in this study considered hearing loss to be serious but 76% of the students believed that they would not lose their hearing until a greater age. Although 66% of the students had experienced tinnitus, 58% of these students reported not being concerned about it. These results suggest a critical need for promoting healthy hearing behavior among college students. Possible strategies could include improved education, experience with simulated hearing loss for extended periods and availability of cosmetically appealing or invisible HPDs with uniform attenuation across the frequency range.

Several case reports suggest that some individuals are susceptible to hearing loss from opioids. A combination of noise and opium exposure is possible in either occupational setting such as military service or recreational settings. According to the Drug Enforcement Agency of the U.S. Department of Justice, prescriptions for opiate-based drugs have skyrocketed in the past decade. Since both opium and noise independently can cause hearing loss, it is important to know the prevalence of hearing loss among individuals who are exposed to opium or both opium and noise. The purpose of this research was to evaluate auditory sensitivity in individuals with a history of opium abuse and/or occupational or nonoccupational noise exposure. Twenty-three men who reported opiate abuse served as participants in the study. Four of the individuals reported no history of noise exposure, 12 reported hobby-related noise exposure, 7 reported occupational noise exposure including 2 who also reported hobby-related noise exposure. Fifty percent (2/4) of the individuals without any noise exposure had a hearing loss confirming previous reports that some of the population is vulnerable to the ototoxic effects of opioids. The percentage of population with hearing loss increased with hobby-related (58%) and occupational noise exposure (100%). Mixed MANOVA revealed a significant ear, frequency, and noise exposure interaction. Health professionals need to be aware of the possible ototoxic effects of opioids, since early detection of hearing loss from opium abuse may lead to cessation of abuse and further progression of hearing loss. The possibility that opium abuse may interact with noise exposure in determining auditory thresholds needs to be considered in noise exposed individuals who are addicted to opiates. Possible mechanisms of cochlear damage from opium abuse, possible reasons for individual susceptibility, and recommendations for future studies are presented in the article.

In osteoarthritis, the joint cartilage breaks down. Cartilage exists within the incudomalleolar and incudostapedial joints. In addition, the cartilage-covered base of the stapes footplate is bound to the cartilage-covered rim of the oval window by the annular ligament. Thus, higher prevalence of middle ear abnormalities and hearing loss can be expected in osteoarthritis due to degeneration of the cartilage and the subsequent abnormal repair response. In this study, tympanometric and audiometric data were obtained from 15 individuals diagnosed with osteoarthritis and 15 gender- and age-matched individuals without the diagnosis of arthritis. Results showed a significantly higher prevalence of middle ear abnormalities and hearing loss in ears with arthritis when compared to the control group. Interestingly, osteoarthritis and hearing loss are considered among the top chronic health concerns in older individuals although the connection between these two conditions has not been previously reported.
