In its report “The Chinese acoustics research that might help shield submarines from sonar” today, SCMP quotes Yang Jing, associate professor of acoustics at Nanjing University, as saying, “It (the technology) has borrowed many ideas from quantum physics, which shed new light on sound problems.”

China’s Prof. Pan Jianwei is a leading quantum physicist in the world. Pan had earned fame in the field in the West but could not even find a teaching job in a Western college. China treasured him, has attracted him back and provided him with abundant funds for his research. We are not sure what contribution he has made in the development of that technology. Anyway, the importance China attaches to scientific research and the abundant funds it provides will certainly give play to Chinese talents and achieve wonders.

The technology of using rings of aluminium alloy to prevent sound wave from bouncing back is but at its initial stage. However, it shows China’s potential to become world leader in science and technology.

    It is said that No submarine can escape low frequency detection such as crew member’s voices, hence invisibility cloak coating materials to shield submarines from sonar or hearing devices.

    There are many ways to detect and track submarines. Sound via sonar is just one.
