| Many species on this planet use sonar and sound to | | | | hearing aids and a pinging sound wave of a certain |
| navigate in the dark or locate objects around them in | | | | frequency, one, that was beyond the human hearing |
| the ocean. Bats and Dolphins for instance use sound | | | | realm. It should work perfectly. It has many |
| waves in this fashion. Not long ago an astute | | | | applications in many industries and some military |
| gentleman stated; "Why, we could make device that | | | | applications as well. |
| was very small and attached to the human ear or | | | | In fact, before retirement, I can recall that we used |
| implanted to act as a human sonar." | | | | to use sonar waves at the car washes to know |
| Well, is this even possible? I mean that would be | | | | where the car was, now they use optical sensors. |
| pretty interesting as others have recently stated | | | | Small UAVs and robots have a sonar-like system in |
| with regards to this concept. Do you think it is | | | | them. One of the recent DARPA grand challenge |
| possible? Personally, I am pretty certain that yes it is | | | | contestants used stereo-type sonar. Well, why not |
| possible, but I have not pursued this concept, as I've | | | | make one to interface with the human ear, piece of |
| been working on other stuff. Still, I do not see why | | | | cake. Hmm, I bet they already exist, I am sure |
| we couldn't build it or make such a device. | | | | someone has considered this the prior? Think on this. |
| It would be very easy to design with high-efficiency | | | | |
