LO3: Linking audio to visuals and applying audio effects

Once of the main parts of my short film that required audio effects was the scene where the power cuts. When filming the origonal footage, the footage just changed to dark with no sound signifying a power cut at all. However I was able to source a sound that mimics a power cut from the website Freesound.org, called Power Down, which can be found here:

Using Adobe Premiere, I simply added the sound underneath the footage in a position which linked up with the visuals perfectly, the screen shot of the position can be seen below:

Another piece of sound I need to include, was the sound of the computer glichting along side the visual of the computer glitching, in order for it to seem more realistic, as if it is a real glitch and not just a video playing on the laptop which I animated. 

Due to an error with the recording camera, there was one piece of footage where you couldn not hear the office worker typeing. Therefore I had to source the sound of someone typing on freesound, and then link it along side the visuals of the office worker typing. The problem is, in the final edit, you will notice the change in sound to the other scenes where the office worker is typing.
