They HEAR using their ears but they use the echoes of the sounds they make to build a "sound picture" of their surroundings. This is used to avoid collisions and to catch prey. This use of sound and echoes is called "echo location".
Insectivorous bats mostly hunt at dusk or at night. Rather than locating insects by sight, they locate them using echolocation. Echolocation is a method of using sound pings and then listening to the echos. From the echos, the bats can tell where objects, obstacles, and even insects are.
Bats are known NOT to hear. They use Radar and Echos to discover things about their prey (Size, Distance Away, What it is, Etc.) But some scientific disclaimers have proof that they have sight such as the fact that they can avoid collisions in the night with out using sound radars.
No one is able to hear ultrasound; the frequency of the sound used is far higher than the audible limit of any person or animal. A sonographer will conduct an ultrasound. Ultrasound in the same way that bats navigate - by listening to echos. ultrasound is reflected in propotion to the density of soft tissues. an ultrasound displays the results of these echos.
Most bats catch prey using their ears through a process called echolocation. They send out a high pitch (high frequency sound) which is above the human hearing range, and this sound echos off of their surroundings. Their ears are designed to catch this echo, and then they process the echos to get a sort of "mental image" of their surroundings. See Related Links for more info.
Bat's use echo to find there prey since they have poor eye vision.
Bats can hear every thing around them
OBGYN uses Ultrasound device to look into internal organs in the body. Ultrasound is using the echos of very high pitch sound to create a picture of a the organs.
It means "Echos From my", it is an uncompleted sentence.
Echos o' Faith was created in 1996.
Through echo-location. They emit high-pitched sounds and by listening to the echos they get a kind of radar picture of their surroundings.
Bats have exceptional hearing abilities that allow them to navigate, communicate, and hunt using echolocation. They can hear ultrasonic sounds at frequencies up to 200 kHz, far exceeding the human range. This acute hearing enables them to detect prey, obstacles, and navigate in complete darkness.
Yes, the word echos is the plural form for the noun echo.
