If a human being can yell for eight years, seven months, and six days at straight, then he can produce sound energy that can heat up a cup of coffee.A baby can cry at 115dB, and his sound is louder than a car horn.Whales communicate with one another underwater, and their sound and songs travel up to 800 km quickly in the ocean.

Frog croaks at 50 to 8,000 Hz, and elephant trumpets at 10 Hz to 10,000Hz.

Howler monkey hoots at 400 Hz to 6,000 Hz.

Male grasshoppers make a loud rasping sound of about 7,000 Hz to 100,000 Hz by scratching their hardened wing cases on the pegs located on their rear legs and listen with their ears that are present on their abdomen.

Dogs have more ears sensitive than a human’s ears so they can hear high-frequency sounds that you cannot hear.

12,000 Hz to 150,000 Hz to find their way in the darkness of night, and they have highly sensitive ears that listen to the echoes.

Bats produce a series of high-frequency clicks i.e.

Flies cannot hear at all they are deaf.

You can hear the different sound because when the sound enters your ear, then the ear also vibrates.

Thomas Edison developed the first-ever audio recording and recited ‘Mary Had a Little Lamb’ in his phonograph in 1877.

Light travels faster than sound so we can see the thunderbolt before we hear its sound.

Sound waves bend when they happen to hit an object or any corners of an object.

The scientific study of sound waves is well-known as acoustics.

So, digital sound recording is always preferable over the analog recording ( 2). However, the digital recordings just have a pattern of numbers which you can copy and correct, if need be, again and again without any distortion. When you play the signal, the stored digital pattern changes back into sound waves.Įven though analog sound recordings create an exact copy of the desired sound wave pattern, creating several copies of the original records can add extra noises and distort the unique pattern. You can record and transmit sound waves to a digital signal, which holds a particular pattern of the desired sound waves in a digital series that you can store on a digital tape, CD, or a computer system. What Is A Digital Sound And Why It’s Better Than Analog Sound? You can also save the model as a magnetic pattern on a plastic tape. You can store auditory waves by using analog recording technique, in which you store sound wave pattern as a wavy groove cut into a plastic disc. (Notice how the period of this sine wave is half of the original sine wave.A microphone can change the sound waves into electrical signals that fall and rise in a particular pattern which is identical to the sound wave pattern that you try to record. You can see the new graph and hear the sound below.

If you know anything about music, we still get the note A, but now it's one octave higher. If we double the frequency (so the sin wave completes 880 cycles per second), we get a note which sounds almost the same, and yet it's higher. If you figure out the period of this function (using the theorem from class) you'll see that this wave has 440 complete cycles every second. For example, if you know anything about playing a piano, the note A above middle C produces a wave shaped like. Guess what: those sound waves are shaped like sine waves. One example is sound: whenever you play an instrument, or listen to your stereo, you're listening to sound waves. You might wonder, 'Why do we care? Does this ever show up in real life?' The answer is most definitely 'YES.' Sinusoidal waves (or sine waves for short) have turned out to be essential to understanding how our world works.

We've studied the graph of in some detail in class.
