The device helps people talk to dolphins

Dolphins are a species that is able to recognize sounds far beyond humanity. They can distinguish between different sounds, at very low frequencies and frequencies, which they can hear as well as produce sounds at low frequencies below 20 kilohertz and up to 150 kilohertz. All over the ability to sense human sound.

Although dolphins may not produce music like humans, they can also communicate at multiple frequencies at the same time. Dolphins use sound not only for communication, but also for exploring the surrounding environment and prey in the dark (this ability is called echolocation).

To date, most of the dolphin's audio studies have focused on recording and measuring sounds. Relatively few audio-response experiments are so difficult for humans to emit low frequencies, as high as dolphins do, says Heidi Harley, a comparative cognitive psychologist at Newly-Formed University. Florida in Sarasota.

Scientists have developed a loudspeaker that produces sounds like dolphins that people can use in echoes. This device consists of voltages to convert electricity into physical movement and vice versa. It is capable of broadcasting high frequency and low frequencies, with a very wide range of sounds.

These speakers were only developed a few weeks ago, so scientists studying dolphins have not had a chance to experiment. The idea of designing this speaker is to broadcast a specific sound and then record the answers. One day, this way will reveal what dolphins "say" and allow humans to communicate with dolphins.

However, Harley's psychologist says that scientists now know very little about how dolphins classify their own sounds. At the same time, there is still a great deal of perception and basic sound analysis to be made before the claim that humans can communicate with dolphins using the sounds that this device provides.
