Corrected entry: When Bond and Tibbett are sneaking into the stables, they left a tape recorder in Bond's room playing sleeping/snoring noises to pretend Bond is in his room sleeping. When Zorin and Mayday look for Bond in his room the tape recorder isn't there any more. It is absolutely quiet in this room.

Correction: The tape had run out by the time Zorin and Mayday went into Bond's room which is why it was quiet. As for why they didn't see it...either it was an oversight, or they just didn't care.
