Running water sounds are not just for those who are afraid of drowning, as the deadening effect of water sounds can be an important and safe way to hear an orgasm sound, a new study has found.
A team of researchers from the University of Pennsylvania found that a sound that resembles drowning sounds, but with a deadening component, could be heard by people who are at high risk of drowning or those who have recently drowned, including people who have already suffered a cardiac arrest.
“The study has a lot of limitations, but it’s a very good study to say that the deadens can be very powerful for people,” said lead author Dr. Yuki Iida, an assistant professor of psychiatry and neuroscience.
“If you’re drowning, the deadeners might be especially useful for people who might be drowning in a state of hypothermia, because they don’t have a pulse.”
The deadens are made up of a combination of air molecules and the vibrations they produce.
When the air molecules travel through the body, the vibrations of those molecules are amplified, making them sound louder.
This amplified sound then travels to the brain, where it is heard as an orgasm.
The study, published in the journal Current Biology, examined the sound and its effect on the brain of 23 people who were at risk of cardiac arrest and who had recently experienced a cardiac death.
The participants were shown images of the heart and a deadened heart sound.
After seeing the images, participants were asked to rate how important the sound was to them.
The people who thought the sound made them feel alive, or very important, rated it highly.
The researchers then found that those who felt the sound important rated it as more important than people who rated it very important.
“It was interesting to see how the deaden was able to cause people to have a higher rating of importance than they would have had from having a heartbeat,” said Dr. Iida.
“We also found that people who felt important felt a stronger effect of the sound than those who did not have that feeling.”
Dr. S. Senthil, an associate professor of neuroscience at Harvard Medical School, said the findings are “really exciting.”
“It really does appear to have this strong emotional impact,” said Senthi, who was not involved in the study.
“This really is an important study, and we need to do more of these experiments to understand more about the relationship between sound and emotion.”
Another study, also published in Current Biology last month, found that when a sound like the one the researchers described has a “deadening effect,” people’s ability to hear it is also reduced.
Researchers found that hearing the sound reduced participants’ ability to identify emotions, feelings and thoughts associated with the sound, and also increased participants’ tendency to rate it as important.
The authors said the study is not yet conclusive about how the effects of sound on perception are mediated by the brain.
They also noted that they were unable to measure the effects on participants’ heart rates, which could affect the results of future studies.
In the future, they plan to conduct more studies on the effects and the possible mechanisms by which sound can affect perception.
