A new study has shown how Japanese horseshoe bats (Rhinolophus nippon) handle noisy environments ...

When tiger beetles hear a bat nearby, they respond by creating a high-pitched, ultrasonic noise, and for the past 30 years, no one has known why. In a new study, scientists lay the mystery to rest by ...

For many nocturnal moths, hearing sound waves is a matter of survival in the night sky. Their ability to detect ultrasonic calls emitted by bats determines whether they escape or become prey. This ...

Sound plays an important role for many animals, helping them navigate and hunt. Echolocation is the ability of animals like bats and dolphins to locate objects by emitting sound waves and interpreting ...

Bats have been using sonar to navigate and communicate for ages, and now humans can do the same, thanks to lightweight and efficient ultrasound microphones and loudspeakers developed by physicists.

Researchers played simulated bat echolocation calls in the laboratory and found that egg-bearing A. nigrisigna stopped flying when exposed to high pulse repetition rates. This behavior could be ...

What do bats, dolphins, shrews, and whales have in common? Echolocation! Echolocation is the ability to use sound to navigate. Many animals, and even some humans, are able to use sounds in order to ...

Ultrasound refers to any audio signal above the range of human hearing. Generally that’s accepted as 20 kHz and up. Unlike electromagnetic signals, ultrasonics are still operating in a medium – ...

Bats, as the main predator of night-flying insects, create a selective pressure that has led many of their prey to evolve an early warning system of sorts: ears uniquely tuned to high-frequency bat ...
