Prevention of voice disorders among students at the University of Heidelberg: findings and implications

Purpose & theoretical background: The training of verbal communication skills is a high priority at universities. Training the voice plays a special role here, as many professions are dependent on a well-functioning voice. Speech and voice-intensive professions (professional voice user) in which the stress and strain are particularly high, work-related voice disorders occur more frequently. In general, voice problems have a negative impact on work performance and quality of life. This study examines the effectiveness and benefits of the methods implemented at the university to prevent voice disorders and investigates the question of which implications make sense.

Research methods: Prevention measures investigated are voice screening (such as voice handicap index, voice range profile measurement, perceptual analysis of voice sound) with counseling, face-to-face voice training (including digital self-learning tools, learning diaries and learning by teaching). The objectively collected screening results and the subjective reflections of the participants are available and have been evaluated. In addition, a questionnaire was also evaluated to assess one`s own voice and possible risk factors. The study was conducted among students who had taken part in voice screenings and voice courses.

Findings: Sixty students were included in the study, 30 prospective teachers and 30 from other subjects of study. The results reveal how important appropriate voice training is during studies. Numerous vocal abnormalities were identified and could be remedied early on, e.g. through voice training. The evaluation of the questionnaires showed a good agreement between the subjective reflections and the voice screening results.

Discussion: A systematic recording of vocal risk factors is possible. Due to the large number of voice dysfunctions that are already apparent during studies, participation in preventive voice prophylaxis programs should be mandatory, especially for future professional voice users. Voice screening with counseling has proven particularly helpful in encouraging students to take care of their voice and communication skills. If voice problems are clearly evident, a laryngological examination should be performed.
