Today's halls and community facilities are often designed without any thought into the acoustic problems that can occur.
They usually serve a purpose for a number of different activities and are large open spaces with solid surfaces for sound to reverberate in.
A group of people like a class for fitness or a hall full of school children, can make people raise their voices and exaggerate the problem.
We have experience in schools, churches and community halls and use different ceiling and wall panel solutions to greatly reduce reverberation problems.
