From these trailers i have found that the best way to create tension is through mostly non-diegetic sound because it will connote the moods and help to build a crescendo. This was responsible within our product because we made sure that the non-diegetic main sound was beneficial towards our production and enabled us to get the best out of the action. As well as this, we took careful consideration into choosing this as it had to build tension as well as allowing the audience to focus on what they could see, not hear.
Diegetic sound benefited our product. For example, we used ambient sounds of birds singing that was effective because despite the fact that we wanted to create a sense that most of nature was dead, there was still proof of birds. This also led to a natural feel and seemed to provide recognition and social solidarity as the audiences would consider why they could hear this ambience. Another example was the use of Foley sound when the character was heavily breathing at the end of the title sequence. This again created realism and connoted that he had been running, possibly from the human eaters.
