In a research paper titled "The sensitivity of bone conduction for dental implants," published earlier this month in The Journal of the Acoustical Society of America, researchers at Tongji University in Shanghai describe tests to determine how well implanted teeth conduct sound.
The authors, Fengxuan Ren, Yutong Li, Lidan Chen, Jiaqi Huang, and Jianxiang Tao, explain how it's well-known that bone conduction through natural teeth can produce an auditory effect. But sound transmission through artificial teeth hasn't received as much study.
The results suggest "dental implants were more sensitive to bone conduction than natural teeth and mastoids at some frequencies," the authors observe.
