Noise-induced hearing loss in young people

School Nurses' Role in Identifying and Referring Children at Risk of Noise-Induced Hearing Loss

Young people are likely to experience noise-induced hearing loss (NIHL), as the use of personal listening devices and other damaging factors (e.g., video games) increases. Little research has examined the role of school health personnel in the prevention and early identification of hearing impairment. A 32-item, valid and reliable survey was developed regarding elementary and middle school nurses' practices concerning hearing loss screening and prevention. The survey instrument was based on the Stages of Change theory and the Health Belief Model. A random sample of 800 nurses was obtained from The National Association of School Nurses. A two-wave mailing was used to achieve a 58% response rate. Forty eight percent indicated there were not many educational programs that addressed NIHL in students. Performing hearing screenings routinely can help identify those students at risk. School nurses need to become advocates for policies and programs that mandate hearing screenings and educational programs to help reduce hearing loss.

Effectiveness of “Dangerous Decibels,” a School-Based Hearing Loss Prevention Program

Purpose

To evaluate the effectiveness of the “Dangerous Decibels” educational program in increasing students' knowledge and positively changing their attitudes and intended behaviors related to hearing and hearing loss prevention.

Method

Baseline questionnaires were completed by 478 4th-grade students and 550 7th-grade students. Approximately half of the students in each grade received a 35-min interactive classroom presentation on hearing and hearing loss prevention. The remaining students served as comparison groups. Students who received the curriculum filled out questionnaires immediately after the presentation. All students filled out follow-up questionnaires 3 months after baseline.

Results

Fourth-grade students who participated in the Dangerous Decibels presentation exhibited significant improvements in knowledge and attitudes related to hearing and hearing loss prevention. These improvements were maintained 3 months after the presentation. Seventh-grade students also experienced long-term improvements in their knowledge base. However, attitudes and intended behaviors in 7th graders returned to baseline levels 3 months postpresentation.

Conclusion

The Dangerous Decibels hearing loss prevention program was effective at producing long-term improvements in the knowledge base of 4th- and 7th-grade students. Future studies should include components on peer pressure and should incorporate repeated, multimodality interventions to increase the likelihood of long-term improvement in adolescents.

Perceived Hearing Status and Attitudes Toward Noise in Young Adults

Purpose

To estimate the prevalence of perceived hearing loss, tinnitus, and temporary threshold shift (TTS) in community college students and to see whether those students' attitudes toward noise affected their perception of their own possible hearing loss, tinnitus, and TTS.

Method

Young adults ( N = 245; age 18–27) completed 3 questionnaires: the Hearing Symptom Description, Youth Attitude to Noise Scale, and Adolescents' Habits and Hearing Protection Use.

Results

Perceived TTS and pain associated with loud noise were the most common hearing related factors, followed by perceived tinnitus and hearing loss. The students' attitudes toward noise in their daily environment showed the most negative response, whereas attitudes toward noise and concentration indicated a more positive, or less harmful, response. Chi-square analysis indicated a significant correlation between perceived hearing loss and respondents' overall attitudes toward noise exposure. Hearing protection use was limited for all participants, with the majority reporting never having used hearing protection.

Conclusion

Approximately 6% of respondents reported perceived hearing loss, and 13.5% reported prolonged tinnitus. In general, participants had neutral attitudes toward noise. Over 20% of participants reported ear pain, tinnitus, and/or TTS after noise exposure at least sometimes. Coincidentally, few participants reported consistent use of hearing protection.

Trends in the Prevalence of Hearing Loss Among Young Adults Entering An Industrial Workforce 1985 to 2004

OBJECTIVES

Studies have suggested that hearing loss due to recreational noise exposure may be on the rise among adolescents and young adults. This study examines whether the hearing status of young US adults entering an industrial workforce has worsened over the past 20 yr.

DESIGN

The baseline audiograms of 2526 individuals ages 17 to 25 beginning employment at a multisite US corporation between 1985 and 2004 were analyzed to determine the yearly prevalence of hearing loss.

RESULTS

Approximately 16% of the young adults in the sample had high frequency hearing loss (defined as hearing thresholds greater than 15 dB in either ear at 3,4, or 6 kHz). In a linear regression model, this prevalence decreased over the 20-yr period (odds ratio (OR) = 0.96, 95% confidence interval (CI): 0.94, 0.99). Almost 20% of subjects had audiometric "notches" consistent with noise exposure; this rate remained constant over the 20 yr, as did the prevalence (5%) of low frequency hearing loss.

CONCLUSIONS

These results indicate that despite concern about widespread recreational noise exposures, the prevalence of hearing loss among a group of young US adults has not significantly increased over the past two decades.
