Due to the underground tunnel of the Tokyu Toyoko Line being located near the condominium, there were concerns about the impact of train vibrations from the Toyoko Line. The condominium is planned to have living spaces on the B1 floor and trunk rooms on the B2 floor, and measures against solid sound from vibrations were considered. Before construction, ground vibration surveys were conducted, and based on that data, the vibration and noise environment for the B1 living spaces was predicted, leading to plans for the installation of vibration-damping materials on the underground outer walls. To confirm the vibration insulation performance of the vibration-damping material Vibra, vibration and noise verification measurements were conducted, and it was found that there was no audible solid sound from the subway, and no perceptible vibrations were detected, resulting in excellent outcomes. *For more details, please refer to the PDF document or feel free to contact us.*
