There are appropriate sound level ranges determined by regulations for the intended use of each place. In the room acoustics, finishing material s sound absorption coefficients are used to calculate the reverberation time. Materials such as glass wool, which are widely used in site, are harmful for human health, especially during application. For this reason, as in many fields, the search for natural materials in sound absorption materials has become more important especially in recent years. In this study, it is aimed to produce an alternative sound absorbing material that is not harmful to human health with composites that will be produced by using a natural plant fiber named Luffa Cylndrica. In this context, using the Luffa Cylindrica fibers with epoxy binder, composite material is produced and the sound absorption coefficients of the samples are determined by impedance tube method. Also, the effect of material thickness and fiber ratio parameters on sound absorption performance are examined. The results are presented in graphs and and compared to eachother. The results showed that the material thickness and fiber ratio had an effect on sound absorption performance.
