Gary Rydstrom- The Sound of Saving Private Ryan

In a interview with Gary Rydstrom he explains the different sound techniques he implemented for Saving Private Ryan.

I was particularly interested in the shellshocked effect that he created by recording a seashell. I thought that it was  really simple yet effective way for the audience to see the experience through the protagonists perspective.

I want to create something with the same personal impact for my audio.
