Effectiveness of "Dangerous Decibels," a school-based hearing loss prevention program

Area of Science:

• Public Health
• Audiology
• Health Education

Background:

• Hearing loss is a growing public health concern.
• Preventable hearing loss affects individuals of all ages.
• Effective educational interventions are crucial for hearing conservation.

Purpose of the Study:

• To assess the "Dangerous Decibels" program's impact on student knowledge, attitudes, and intended behaviors regarding hearing loss prevention.
• To evaluate the program's effectiveness in 4th and 7th-grade students.

Main Methods:

• A quasi-experimental design involving 4th and 7th graders.
• Administered baseline and 3-month follow-up questionnaires.
• Compared students who received a 35-minute interactive presentation with control groups.

Main Results:

• Fourth graders showed sustained improvements in knowledge and attitudes post-intervention.
• Seventh graders demonstrated long-term knowledge retention.
• Attitudes and intended behaviors in 7th graders reverted to baseline levels at 3-month follow-up.

Conclusions:

• The "Dangerous Decibels" program successfully enhanced hearing loss prevention knowledge in both age groups.
• Long-term attitude and behavior change in adolescents may require more intensive or repeated interventions.
• Future research should explore strategies addressing peer influence and multimodal approaches for sustained adolescent engagement.
