The sound that bats make is so high pitched that scientists use a program like this to slow down the bat sound so it can be heard.
Description
(At the top of the video is a red frequency line. This line will show the sound an Eastern Red Bat makes in the wild.
In the middle of the video is a white line that separates the red frequency line from a green frequency line.
Below the white line is the green frequency line showing the background sounds of the recording. The words Eastern Red Bat sits under the white line on the bottom right just before the image of the Eastern Red Bat.
There is an image of the Eastern Red Bat face in the bottom right corner of the video. The bat has small ears like a cat’s ears and they sit just behind his eye on the side of the bat’s face. The bat’s nose is squished in like the nose of a bulldog. It has large lips that surround its mouth. The lips are flat like it’s getting ready to make a raspberry sound. Its fur is tan and white. The tan fur is around the bat’s face. The white fur starts just below its ears and covers the rest of the bat’s body.
When the video starts, we don’t hear anything. The player line goes through 21 frequency bumps. The text at the bottom of the screen just above the white line says “Sound played at normal speed.”)
Narrator: The sound that bats make is so high pitched that scientists use a program like this to slow down the bat sound so it can be heard.
(After the narrator speaks, The text above the white line changes to “Sound Played at one-eighth speed”. As the player line moves through 11 frequency bumps on the red line, we hear a chirping sound that is evenly spaced. Like the sound of a stopwatch counting down the seconds.)
