Noise disturbance at airports negatively affects people's health. In this study, Ahwaz International Airport in Iran was selected as the case study due to the very long resonance measured in the middle frequencies of 5-10 seconds. To overcome this acoustics problems, we examined eight square sound absorbing panels installed on the walls and the ceiling of the airport lounge and was simulated using EASE 4.4 software. In our research four variables including acoustic time index (RT, or main index), auditory error coefficient (ALconse), speech transmission index (STI) and total sound pressure level (SPL) were evaluated according to the international standards of ISO3382 and ISO 3382-1. After the simulation, it was concluded that our Model A compared to other sound absorbing panels, showed the lowest sound pressure at different frequencies using the above indices.
