Hello Happy Friends!
Are you ready to learn?
Iโm Sara, and today, weโre going to talk aboutโฆ Well! Just listen!
Sounds good huh? Today, Weโre going to talk aboutโฆ Sound!
-
For sound to exist, there needs to be something, or someone that produces it. Like this guitar!
A medium through which it can be transmitted, like air.
And of course, an ear to receive it.
-
When I play my guitar stringsโฆ
I produce vibrations that travel in waves to our ears, thatโs why we hear them.
-
Soundsโ speed depends on the medium it travels through.
In solids, like iron, sound waves travel at great speed!
In liquids, like water, they travel a little slower,
And in gases, like air, is where they travel the slowest.
-
But, if sounds are waves, why do we recognise sounds when we hear them?
Why do we recognise our parentโs voice? Or a dogโs bark?
Well itโs easy peasy! We recognise them because of every soundโs properties, or characteristics.
-
There are three properties:
Intensity, pitch and timber.
Intensity lets us identify if the sound is loudโฆ or softโฆ
Thanks to the pitch, we can tell if the sounds are high (pitched) or low (pitched)
And by the timbre, we identify what or who has generated the sound.
For example, if it has been generated, by a fluteโฆ
โฆA guitarโฆ
...A dog!...
...Or a cat!
-
Lastly, before I say goodbye, hereโs a fun fact! Do you know what Echo is?
Echo, is when sound waves bump against an obstacle, change their direction and shortly after, we can hear the sound repeatedly.
-
Thatโs an echo, and Iโm that youโve heard it more than once. But if you havenโt... listen up!
Happy Learning!
So cool!
Bye happy friends!
I hope youโre always ready to learn more!
