Why Men Don't Listen

British researcher Michael Hunter discovered  when women are speaking at great length, men tend to tune them out. Now men have a scientific excuse. Female voices  are more complex than male voices, making men's brains work harder when listening to them. The shape and size of female vocal cords lead women to speak with a greater range of sound frequencies than men. Women also have a more natural melody in their voices. Listening to female voices activates the auditory center of a main's brain, which must analyze the different sounds at the same time he's interpreting words.
