sorry for the spelling mistake. here it is. Ultrasound is a type of sound wave that has a frequency of over 20,000 so it is nearly impossible for a human to hear it. Bats use it to communicate and to see as they have bad eyesight. They use their echo ultrasound to reflect sound so they know if something is in front of them. Humans use ultrasound to see living cells in the body like when a woman is pregnant they it to scan and measure the baby's heart rate. Mice also hear ultrasound and people use special equipment that use ultrasound to scare the mice and other insects away.
What else can I help you with?
Your ulrasound at 15-16 weeks said its a girl can this conclusion be accurate?
They're brave telling you. A girl is more difficult to see than a boy. You can see their bits at this early age, it depends how confidently you were told.
I had a ulrasound they thought i was pregnant as they could see a sac but the blood test came back neg is that possible could it be a cyst?
Could possibly be a pregnancy I'm not sure when the hormones start to show in your blood versus the rate at which a sac would show up on screen. They should have explained this to you at the time so you understood better.
Seven weeks pregnant hcg level at 3000 why no fetus on ulrasound?

How do bats hunt with ulrasound?
Bats emit high-frequency sound waves and listen for the echoes that bounce back to locate their prey. This process, known as echolocation, allows them to navigate in complete darkness and accurately pinpoint insects in mid-flight. Bats can then adjust their flight path based on the echoes received to intercept and catch their prey.
What is the difference between ultrasonic and ultrasound?
Ulrasound is sound that is too high pitched for the human ear to hear. Ultrasonic is used to describe a sound as being an ultrasound. So, ultrasonic is an adjective, and ultrasound is a verb.
