Abstract
This paper describes a modern composite timber - concrete ceiling construction. It also compares and evaluates the acoustic qualities (sound insulation and a level of acoustic pressure of impact sound), which were measured on a sample of a 3 x 3.6 m size in the experimental measurements in the acoustics testing laboratory certified by CSI Zlin. In the first case, the construction is evaluated as a supporting ceiling panel without any additional layers. In the second and third option it is evaluated as a ceiling construction with structural modifications (a supporting ceiling with some floor layers of different combinations).
