Click on the create a new project button, give it a name, and then click create.

Here you can start a new project or manage your old ones. Loudness is a measure of sound intensity taking frequency into account, and is called a A-weighted decibel, dB(A), or a phon. When you first open Lightworks, you will see your project screen. This is a standard threshold, but it also depends on frequency.

Sound intensity can be found from the following equation: exts o is the reference pressure which is 20 micropascals or 0 dB, and s is the observed sound pressure.The human ear has a standard sound threshold of 120 dB, which expressed logarithmically is around 10 12.
