Scientists built microphone into teeth
Four inventors from Maryland and Virginia have come to the idea to create microphone that can be installed from the backside of teeth.
According to their words this will protect the device from external vibration which anyway occurs while using of jawbone microphone.
This device can be useful in those conditions where the usage of ordinary microphone is complicated, for example, on a plane or on the road when the level of noise is extraordinary strong. A new device is built into teeth as crown. Using low-frequency radio transmitter a signal is transmitted to headphones.
Thanks to function push-to-talk one can operate microphone by words. According to inventors, the system can work in the presence of noise with frequency 160 dB, that is higher than the noise of jet plane.
