Background: In systems such as police force that any person is considered
as an asset of the organization, noise pollution can lead to the behavioral
abnormalities such as aggression that may cause occupational burnout.
Therefore this study was conducted to compare aggression between Musicians
and Non-Musicians groups of NAJA.
Materials and Methods: The present study was a cross-comparative research
and tests were applied on all members of music group (n=42) of NAJA
university. To access the control group, we selected 42 subjects and matched
them with experimental group. To measure aggression we used Buss-Perry
Aggression Questionnaire and for collecting demographic information we
used a questionnaire designed by authors. Data processing was performed
using student T-test and Pearson correlation coefficient by SPSS 20 software
package.
Results: The results of the comparison between two groups indicated that the
score of overall aggression was significantly higher in music group than other
one. The similar difference was also achieved for physical and verbal, anger,
and hostility subscales of questionnaire (p=0.001). Moreover, we found the
significant positive relation between job history and aggression with Pearson
correlation (p=0.011). It means that the more year people work in music group,
the more aggression they have.
Conclusion: Findings obtained from this study indicated the importance of
high noise exposure effect on behavioral changes such as aggression among
members of music group. The authorities should adopt and rigorously
implement approaches to reduce and control exposure to this stressful
environmental factor for the mentioned group. Allocation of suitable space for
practice and providing acoustic space, proper scheduling for work and rest and
psychological interventions to reduce aggression and increase compatibility
in workplace are the most important approaches to achieve this goal.
