Large gymnasia are utilized for multi-purpose events such as sports, performance, and a range of events. However, old gymnasia show many acoustic defects and in order to correct them, changes of finishing materials and partial interior-design are employed for improvements of their acoustic performance. Nonetheless, some research are required to be carried out because subjective responses actually experienced by audiences might not be improved after these changes. With respect to this, the research has attempted to look into differences of the subjective responses between before and after acoustic performance improvements made at five old large gymnasia. In the cases of a gymnasium where the Reverberant Time (RT) has been shortened, the reverberant, the loudness, and the diffusion have been decreased but the definition, the clarity, the intimacy, the balance, and the warmth have been increased. In the cases of a gymnasium where the RT has been lengthened, the subjective responsese has shown the opposite result to the case of the RT shortened except for the warmth. Therefore, subjective responses illustrate positive reactions after improvements of acoustic performance have been made as adjusting changes of finishing materials, sound absorbing power, and room constance. This result is thought be useful for design and refurbishment of large gymnasia in the future.
