Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
There are several factors in the classroom that increase teacher's risk of voice disorders. One of the most significant is high noise level during lessons. This study explores the noise conditions the teachers are working in and how these conditions are related to the voice parameters and symptoms.
Finally, the study aims to determine whether classroom noise level can be lowered by improving classroom acoustics and by noise reducing workshops for teachers and pupils.

RANDOMIZED
PARALLEL
Group 3. Controls. No treatment during control period. After the control period participants are having Voice therapy or Voice therapy with carryover strategies.
TREATMENT
SINGLE
Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Voice therapy
An individually tailored voice therapy where the order and length of voice treatment methods will depend on the nature of each subject's voice problems. The intervention will take eight weeks and average of eight sessions (a' 45 min).
Voice therapy
Voice therapy with direct and indirect therapy elements.
Voice therapy with carryover strategies
A voice therapy as described above and an enhanced carryover program. By carryover we mean the process of extending new vocal skills outside the clinic. It includes supplementary tasks and reminders that will be tailored individually out of those direct and indirect methods that the subjects have adopted during therapy sessions. Additionally, the teachers will be doing vocal warm-up and relaxation exercises together with their pupils int the beginning and in the middle of a school day. The intervention will take eight weeks.
Voice therapy with carryover strategies
Voice therapy with direct and indirect therapy elements and supplementary tasks and reminders.
Control group
No intervention during eight weeks since this group will act as a temporary control group. After eight weeks, half of the participants in this group will be provided with Voice therapy and half with Voice therapy with carryover strategies.
Control group
No therapy during eight weeks. After the control period half of the group will be provided with Voice therapy and half with Voice therapy with carryover strategies.
