New York - Two years ago, two scientists who said that a woman's voice more attractive during fertile than those during menstruation and after menstruation.
Journal of Evolution and Human Behavior in 2007 reported the lap dancers earn 80 percent more tip when you're ovulating or fertile period than during the coming months.
Last year, a study in Germany showed the voice of women in the menstrual period tend to be heavier and less 'friendly'.
According to the man who listened to the tape, there are four indicators to recognize the voice of women who are menstruating. Namely, mood (good vs. bad), quality (hard vs. soft), pitch (high vs. low), and speaking rate (fast vs. slow).
"Production vocal (voice) is closely related to the body's organs," said Pipitone. "For example, the cells larynx was almost equal to the vagina and it has a similar hormone receptors."
Usually women who are menstruating can be determined by observing the behavior that is being moody.
Turns out it's not just a simple way to identify if a woman is menstruating. More recently, a study published in the Journal of Ethology declared a menstruating woman can be known from his voice.
In this research, a psychologist named Nathan Pipitone from Adams State College and Gordon Gallup, SUNY-Albany, New York, asked three groups of men to listen to voice recordings of ten women who have a menstrual cycle is different. There are currently coming months, the fertile period, and some are not.
All the recordings were played in random order. The three man group was then asked to guess the voice of the woman who was having her monthly cycle.
As a result, the men were able to recognize the voice of a woman who was coming month. "As much as 35 percent of their allegations true," Pipitone said, as quoted Dailymail, Sunday, January 29, 2012. "This is a significant number."
