In today's world, noise has become one of the most important harmful factors in the workenvironment. Due to the importance of mental activities in office jobs, and considering that this group of workers needs a quiet environment to concentrate and handle their affairs, providing acoustic comfort will greatly impact these people's job and performance productivity. The present study aimed to provide acoustic comfort through the acoustic design of the newly constructed administrative department of the School of Public Health, Hamadan University of Medical Sciences. In this study, noise control measures based on structural interventions were planned and implemented based on the plans of the rooms designed for the office space. For this purpose, the necessary information about the design of the rooms was collected, and the design of the walls was done using different sandwich materials based on the calculation of transmission loss (TL) and ISO 15186 standard. In order to control the noise reflection in the inner surfaces of the rooms, acoustic tiles were designed and implemented on the ceiling, and their effectiveness was measured by measuring the reverberation time according to the ISO 3382 standard. Considering that the main source of noise in office environments is speech and conversation, the noise absorption coefficient of surfaces and TL in conversation frequencies (2000-1000-500-250 Hz) were evaluated more precisely. According to the design, the minimum and maximum areas of the rooms were estimated to be 23.42 and 32.27 square meters, respectively. The measurement of the noise transmission loss between office rooms showed that the highest transmission loss occurred at 8000 Hz and the lowest at 31.5 Hz. Also, the average noise reduction in conversation range frequencies (2000-1000-500-250 Hz) was 24 dB. The average reverberation time in the rooms was 0.77 seconds in the frequencies of the conversation range. It can be concluded that structural interventions based on combining several sandwich materials with optimal design in terms of noise transmission loss and reverberation time control can be useful to provide acoustic comfort and noise control in office environments. If the walls that separate the office environment rooms were designed and built with appropriate thickness and density, it can prevent noise transmission between the rooms. Also, using materials with a suitable noise absorption coefficient for the internal surfaces of the rooms can effectively prevent the reflection and amplification of noise inside the office environment.
