How do bats avoid colliding with objects while flying? Scientists, using tiny microphones on bats' heads, found that bats tweak the frequencies of the sounds they emit to detect and maneuver ...

Imagine navigating a pitch-black room and knowing exactly where every object is without ever switching on a light.

Bats can learn to mimic specific sounds, which puts them into an elite group of animals capable of this. ... microphones and remote-controlled feeding devices that delivered them rewards.

These bats can use leaves as “sound mirrors” for ... essentially just a speaker to reproduce the five primary ultrasonic frequencies of bat calls, with a microphone right next to it to mimic ...

They found that the sound had to be played at just the right moment and at the right frequency, just as the bat was homing in on the moth. If they played the jamming call too early, it didn’t work.

Bats use sound to navigate their surroundings in the dark and now a robot called Robat can do the same. ... equipped with a speaker to mimic a bat’s mouth, and two microphones, ...

Audio signals are analog and their amplitudes vary based on how close the sound is to the microphone. [WilkoL] wanted to pick up bat sounds as far away as possible, so he cranked up the gain of ...

Robot + bat = a new bot that uses an echo-based sonar system to get around and map new surroundings. Robat the robot mimics bats, using sound alone to navigate - CNET X ...

A species of bat has been observed for the first time interfering with the sound signals of competitors to "steal" food.

Bats were "jammed" the moment they were about to home in on their insect prey, making them miss their target. The rival that emitted the call was then able to capture and eat the insect for itself ...
