Men do have trouble hearing women: research
Men who are accused of never listening by women now have an excuse - women's voices are more difficult for men to listen to than other men's.
Reports say researchers at Sheffield University in northern England have discovered startling differences in the way the brain responds to male and female sounds.
The research shows men decipher female voices using the auditory part of the brain that processes music, while male voices engage a simpler mechanism.
The Daily Mail quotes researcher Michael Hunter as saying, "the female voice is actually more complex than the male voice, due to differences in the size and shape of the vocal cords and larynx between men and women, and also due to women having greater natural 'melody' in their voices".
"This causes a more complex range of sound frequencies than in a male voice," Mr Hunter said.
The report says the findings may help explain why people suffering hallucinations usually hear male voices - the brain may find it much harder to conjure up a false female voice accurately than a false male voice.
The research is published in the specialist magazine NeuroImage.
