Sources close to production have said that Warner Bros is aware of the sound issue, with one insider saying that the studio is "scared to death" about "the Bane problem".
Nolan has responded to requests to change the sound mix by saying that he will only tweak it slightly rather than completely change it, according to The Hollywood Reporter.
An executive said: "Chris wants the audience to catch up and participate rather than push everything at them. He doesn't dumb things down. You've got to pedal faster to keep up."
Christian Bale, Gary Oldman, Michael Caine and Morgan Freeman will reprise their roles in The Dark Knight Rises, while Tom Hardy (Bane), Anne Hathaway (Catwoman), Joseph Gordon-Levitt (John Blake) and Marion Cotillard (Miranda Tate) will take on new roles.
The Dark Knight Rises opens in cinemas on July 20, 2012.
