Sound : Hearing birds chirping, beethoven's symphony sea's wavery movements is a delight to ear. So, how does these sounds are produced? Sound is a vibration produced as an acoustic waves where the internal structure of eardrum is delight to hear the vibration at a certain frequency.

 SOUND 

We encounter a massive situation that is being allied with sound in our daily life. Imagine a life without sound it would lead to miscommunication and miscarriage of informations. A bat survives at night only through ultra vibrations. A beings existence is at it's best with the vibrations and possibility of hearing. The vibrating body causes the medium such as air water and so on to produce sound through vibration.

How is sound defined?"sound is a mechanical disturbance from a state of equilibrium that propagates as an elastic material medium. "

Sound is a longitudinal wave, usually it is measured in metres and represented by lambda (symbol), wave propagates through the air and that passes through specific point in space which is denoted by £, the frequency is traditionally measured in hertz and kilohertz. The human 's range of frequency lies between 20hertz to 20kilohertz. A human ear can't hear a pitch that is more than 20kilohertz. Every being has its own range of frequency and by this I conclude that sound is inevitable part in humans.
