Abstract
This study evaluates the effects of Sound Amplification Systems (SFA) on reducing vocal strain in daycare staff and enhancing children's concentration in noisy environments. Utilizing a mixed-methods approach, structured questionnaires were distributed to 11 daycare staff members in Turku, Finland, to gather both quantitative and qualitative data on their experiences with SFA. The analysis revealed that SFA significantly lowered vocal strain for staff, especially during group activities, and improved children's engagement by making speech more intelligible amidst background noise. However, practical challenges such as SFA mobility and adaptability in diverse settings were identified. The findings suggest SFA's potential benefits in early childhood educational settings, while also highlighting the need for further research to address implementation challenges and confirm these preliminary results with a larger participant sample.
