Audience Feedback - Radio advert

At this stage I completed my advert except from the introduction. I didn't know how to start the advert so I made four introductions. One without anything at the beginning, one with music, one with the sound of a stomach and one with wind. I am trying to find out which advert is most suitable for my radio advert and which one people prefer. Here is a tally showing which introduction people preferred.

From this I found out that people prefered the music introduction. Therefore I shall use this In my final Radio advert.
