Hi Friends!
Hi. It’s me.
Oh hang on. You don’t know who I am?
Shhhhhhh. Here’s an Katie Ledecky quote.
“I would encourage you to set really high goals. Set goals that, when you set them, you think they're impossible. But then every day you can work towards them, and anything is possible, so keep working hard and follow your dreams. ”
Sound waves travel into the ear canal until they reach the eardrum. The eardrum passes the vibrations through the middle ear bones or ossicles into the inner ear.
The inner ear is shaped like a snail and is also called the cochlea. Inside the cochlea, there are thousands of tiny hair cells. Hair cells change the vibrations into electrical signals that are sent to the brain through the hearing nerve.
The brain tells you that you are hearing a sound and what that sound is.
So, here we are, whenever we speak we produce sound waves. And by demodulating r converting in to vibrations we can hear the Voice it contains.
My point is people are speaking from the day they born and is produce infinite numbers of sound waves in atmosphere. Sound waves which are produce are not demolish as per conservation law. Defiantly they losses it strength but there are present around us.
If somehow we found the way to convert this waves in to vibration and increase its strength, then we can hear the voice is produced long ago.
So these phenomenon leads to infinite source of information around us.
- Then we can hear the voice Einstein which are not recoded.
- Then we can hear the voice of our dead fathers and forefathers.
- Then we can record thing by just speaking in atmosphere.
- Then you no longer have to create voice recorder.
- Then you don’t have to take notes from your class.
- Then ….
So, Think about this and if you have some trick or idea just comment below.
