Most people don't realize how important sound is. Viewers usually only become aware of sound when it's bad. High quality audio combined with excellent sound design feels seamless and invisible. That's because it acts as a support for the video. If that support is faulty or clashes with the images, it destroys the effectiveness of the video.
Make sure that the production company shooting your video knows how to create high quality audio. Look at their previous productions and ask yourself: Is the sound quality exceptional? Did the music, if there is any, seem to "fit" with the story and the imagery or did it just feel off? Did the volume of the music drown out the dialogue? Did the dialogue support the imagery? Did the timing of where the dialogue was placed feel "right?"
