There are many vibration courses

available even in massive online open course.

Then why reintroduce vibration course here?

The objective of this course are

first because this lecture is

related with introduction to acoustics course.

I especially try to link

the vibration concept to acoustic concept.

So in whole this lecture,

you will learn about how

the vibration phenomena is related with acoustics.

That's our first objective.

The second objective is,

usually vibration theory has to do with

many complicated mathematical approach.

But in this course,

we try to minimize mathematical approach.

Rather than using complicated mathematical expression,

we will simplify the approach,

try to introduce the basic concept of

vibrations so that you can use

the simple understanding to your practical problem.

So first objective is how vibration is

related with acoustics.
