Bad news, ladies… After listening to more than 2,200 encounters, scientists have finally figured out how to tell if you’re faking something

It’s one of the most memorable scenes in all Hollywood romcoms.

But when Meg Ryan faked an orgasm in a crowded restaurant in Harry and Sally, it was far too loud to be considered real, according to scientists.

Swedish researchers claim to have discovered the sure sign that a woman is faking something, saying ecstatic loud moans and screams – like Ms Ryan behaved in front of other guests – are a rarity.

To reach their conclusions, the scientists listened to audio recordings of bedroom activity for a staggering 34 hours.

They said that if you overdo it with moans that are too loud and too strong, it means the pleasure is probably fake.

According to the scientists, light moaning and grunting are much more common, with very little speaking. And contrary to popular belief, men are just as vocal as women.

“The high-pitched and exaggerated ecstatic screams associated with pornographic films were conspicuous by their absence,” the research states.

Researchers at Lund University analyzed recordings of 2,239 sexual encounters submitted to them by willing couples. The recordings contained 21,314 sighs, 74,422 syllables and 54,145 moans or grunts.

One of the goals of the research was to identify any sounds that might indicate evidence of a fake.

“In both men and women, vocalizations became longer, louder, higher pitched, more voiced and more tonal as arousal peaked,” the psychologists concluded.

“Men are no less vocal overall.” Speech or even minimally verbalized exclamations are rare. “Very few vocalizations could be described as screams.”

Higher volume, excessive singing and longer syllables are signs that a woman is faking something, while pitch variations and the unexpectedness of some sounds are a sign of authenticity, listeners said.

“Based on the observations that women appear to account for the majority of moaning, human sexual expressions are often viewed as little more than conscious attempts by women to please their partners,” the researchers said.

“This assumption is based on self-reports or pornography studies, as no one has yet analyzed recordings of actual human sex.” This study, the first to conduct analyzes of authentic sexual episodes, paints a very different picture.

“According to these new findings, human sexual expressions are, at least in part, genuine and spontaneous expressions of affection, produced by men and women alike in moments of intense pleasure.”

Men were just as vocal as women, but at different times, they found.

While the women’s light moans started a little earlier, the men sighed and grunted until the arousal level became very high, peaking 15 seconds before climax. This was followed by an average of ten seconds of silence for both men and women. Sex therapist and author Phillip Hodson said: “This study raises some interesting questions.”

“Sex is a fearful affair that’s more about bragging rights than business – especially in a world where up to 80 percent of women claim to have faked climax, while up to a third of all men admit the same. “
