The old saying is that moms look behind their heads, but new research shows that common women also have more Sensitive hearing.
The study, recently published in Journal Scientific Reports, sought to investigate the correlations and sensitivity of hearing between multiple factors, including gender, age, and region.
Dr. Patricia Baralesque, from the Center for Biodiversity and Environmental Studies in Toulouse, France, has led a team of scientists to conduct hearing tests on between 13 and 448 individuals. Global Community Ecuador, UK, Gabon, South Africa, Uzbekistan.

Results show that hearing sensitivity is primarily influenced by gender and environment, followed by age and left and right ears.
A new study recently published in the Journal Scientific Reports shows that women may have more sensitive hearing. (istock)
“Our findings highlight the need to challenge existing assumptions and consider both biological and environmental factors. Studying hearing“Balalesque said in a press release.
Scientists measured auditory sensitivity using temporary induction ear attention elimination (TEOAE), which assesses the ability of co-cows to generate and transmit acoustic responses after acoustic stimuli.

Co-cows are spiral cavity filled with fluid in the inner ear that the brain converts into electrical impulses that the brain can interpret, medical sources say.
By analyzing Teoae’s profile, researchers have gained valuable insight into how Cochlea responds to external auditory stimuli.
Scientists measured auditory sensitivity by recording the inner ear of subjects with small sound sent back in response to clicks of sound. (istock)
To calculate auditory sensitivity, the small device played clicks in the subject’s ears and recorded the small sounds sent back by the inner ear accordingly, the findings are detailed.
These return signals created by co-cat cells provide reliable indications of how sensitive the ear is.

The researchers then looked at the signals, such as how strong they were (the unit used to convey the relative intensity or loudness of the sound, measured in decibels), and the frequency at which the ear reacted most strongly.
We also compared variations based on a variety of factors, including subjects’ gender, age, ears being tested, and the type of environment they lived in.
The fact that women showed higher sensitivity means that hearing may be a real biological factor, according to researchers. (istock)
Through the test, Women consistently showed Higher sensitivity at an average of 2 decibels across all sampled populations.
“I was surprised that two decibels had more sensitive hearing in every population measured by women, which accounted for most of the interpersonal variation,” said Professor Turi King, director of the Milner Centre at the University of Bath’s Evolution Center.

“This could be due to different exposure to developing hormones within the uterus, for men and women with slight structural differences in calf anatomy.”
According to King, women also perform well in other hearing tests and voice recognition.
“It may not necessarily be a good thing to have more sensitive hearing in a noisy environment.”
“I don’t really know why this is, but given the detrimental effects of noise on overall health, such as sleep quality and increased, Cardiovascular diseasehaving more sensitive hearing in a noisy environment may not necessarily be a good thing,” she added.
Although age differences were also a factor in auditory auditory (old age is associated with worse hearing), they were less pronounced than gender differences.
People in urban environments had auditory profiles that shifted to higher frequencies, possibly due to the constant urban sound, research suggests. (istock)
Other findings from this study included methods Ecological environment It can affect hearing sensitivity.
For people in urban environments, the auditory profile shifted to a higher frequency. We hypothesized that this could be due to constant low traffic congestion and urban noise in urban environments.

The greatest contrast is seen between high-altitude populations and groups living in tropical environments, the latter having a higher sensitivity to hearing.

This could be the result of living in areas with fewer people in the environment. Essential for survivalthe researchers pointed out.
Professor King said, “We know that humans continue to evolve, so the next question is whether hearing can generally be altered depending on different circumstances, or does genetic adaptation have something to do with it?”
