Bats have good eyesight and most use echolocation (a series of sound waves) to search for food.

Harbor porpoises are frequently exposed to sounds from shipping vessels that register at around 100 decibels, about as loud as a lawnmower, scientists report February 14 in Proceedings of the Royal Society B.

Elizabeth Preston wrote about a blind 13 - year - old boy who has learned to use echolocation, a way of seeing with sound, more commonly associated with animals such as bats and dolphins.

With training and practice, people can learn to use the pitch, loudness and timbre of echoes from the cane or other sounds to navigate safely through the environment using echolocation.

Although the majority of those that use echolocation — emitting sound waves that bounce off objects — to hunt are usually lumped into one group, a new study suggests that some belong in a separate category.

Most crickets distinguish between mates and predators based on the frequency of sound: male crickets produce low frequency calls to attract females, while bats produce high frequency (ultrasonic) sounds for echolocation.

The study appears to be «very solid work,» says Lore Thaler, a psychologist at Durham University in the United Kingdom who studies echolocation, the ability of bats and other animals to use sound to locate objects.

Bats navigate by bouncing sounds off of objects (an ability known as echolocation), so perhaps it's no surprise that their ears work a lot like mini-radar dishes.

Boom Boxes Ultrasonic «boom boxes» that emit continuous high - frequency sounds from 20 to 100 kilohertz deter bats from getting too close to turbines by interfering with their echolocation.

Like some bats and marine mammals, people can develop expert echolocation skills, in which they produce a clicking sound with their mouths and listen to the reflected sound waves to «see» their surroundings.

Modern - day whales that use echolocation possess a melon, or a fat - filled organ in the head, that focuses the sound wave.

These marine mammals have been using echolocation - bouncing high - frequency sounds off underwater objects - to find prey for tens of millions of years.

Frog - eating bats pinpoint their prey by their calls, and have evolved unique hearing that allows them to detect both the high - pitched squeaks of their echolocation system and the low - frequency sound of calling frogs.

Since its discovery, researchers have found that the gene plays a role in the development of language (ScienceNOW, 14 August 2002), that mice need the gene to emit characteristic ultrasonic sounds (ScienceNOW, 21 June 2005), and that it plays a role in bat echolocation (ScienceNOW, 19 September).

It is a sequence of three to four sounds, longer in duration and lower in frequency than the typical echolocation pulses that big brown bats use to navigate.

Bats have an incredible ability to navigate using echolocation, weaving their way around obstacles and finding prey based on the bouncing around of the sounds they emit.
