Acoustics and Ultrasonics standards Group グループのHP

Our group is in charge of the development and dissemination regarding two kinds of primary standards and the related measurement technique. One is acoustic standards necessary for ensuring low noise and safe environment around us. The other is ultrasonic standards necessary for evaluating the performance and safety of ultrasonic medical apparatus and so on.
