A study into how brains perceive voices has come up with the stunning finding that mens brains deal with male and female voices differently.
Men can now give the excuse for not hearing women on the fact the voices are too complex for their brains to decipher.
Researchers from the University of Sheffield studied brain scans of male subjects while they listened to male and female voices.
It was found that the male brain interprets the two voices in different ways with female voices causing activity in the auditory section of the brain, that also processes music, and the male voice sparking activity in the back of the brain.
This research has also explained why when people hallucinate and hear voices they almost always hear a male voice.
Dr Michael Hunter, of the universitys department of psychiatry, said: "The reason these voices are usually male could be explained by the fact that the female voice is so much more complex that the brain would find it much harder to create a false female voice accurately than a false male voice.
"This research could also explain why female voices are considered to be clearer then male voices. This could be linked to the fact that female voices are interpreted in the auditory part of the brain, and are therefore more easily decoded."
