Use this technique to find a formula for the intensity i of a sound, in terms of the sound level β and the reference intensity i0. there will be a quantity (10 db) involved in your calculations. when you enter your answer, leave off the unit db. express your answer in terms of β and i0.

The problem is basically asking us to find a way to find the sound intensity I, in terms dependent on the sound level and the reference intensity .For this purpose we can start from the unit used in the scale logarithmic decibel, that is

Where

I = Acoustic intensity on the linear scale

Hearing threshold

Using the logarithmic properties of the exponents the above expression can be described as:

that is the expression or technique to find the intensity of sound.

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
