This study aims to identify the mental models related to sound of pre-service physics teachers. In this research, case study method which belongs to qualitative research methods was used. 12 pre-service physics teachers, who are currently at the fourth class in the physics education department, participated in this research. In the application process, firstly, researchers asked questions related to sound concept which is prepared for different contexts, to the students and then the simulations are shown related to these questions. The students who obtained the scientifically true answers of these questions by using simulations then explained the reasons of each answer which are wrong, incomplete or contradiction. Mental models of pre-service physics teachers and their understanding difficulties related to sound are revealed by analyzing the data. In conclusion, it is observed that participants have models and understanding difficulties which are also found in the literature. In addition, it is observed that new models and understanding difficulties are revealed.
Key words: Sound / mental model / understanding difficulties / physics education
