Can you imagine not hearing voices? No voice … men?
Male voices are usually voiced. have a much lower frequency than female voices, they are no longer heard
Some might even see it as a benefit or a dream come true, but the truth is that it's a rare disease called reversal hearing loss or low frequency hearing loss .
People with this disease no longer hear low-frequency sounds, such as male voices, hum of refrigerators, microwaves or even thunder, for example.
According to the World Health Organization (WHO), about 466 million people worldwide (5% of the population) have hearing impairments. It is estimated that 3,000 have this disease only in the United States and Canada.
According to the Brazilian Ministry of Health, by the end of 2018, according to IBGE data, in Brazil, more than 9.7 million people – or 4.63% of the population – were hard of hearing.
Absence of male voices
The rare condition of this deficiency has become a new one this month due to a case in China.
A Chinese woman, identified as appealing for the surname Chen, sought a hospital claiming to not hear her boyfriend's voice, according to the AFP news agency and local Chinese media.
Reverse-slope hearing loss is usually hereditary, although it may also occur in times of stress
The night before his arrival at the hospital, otolaryngologist Lin Xiaoqinga, who attended the unit, told local media that she was in the process of vomiting and that she had ringing in her ears.
The doctor diagnosed her with a reverse hearing loss by proving that she was hearing her voice, but not that of a man, nor of the staff of the hospital.
What is the cause of the disease?
In Chen's case, the doctor stated that the illness was caused by a combination of factors ranging from stress and long hours to a few hours of sleep.
With a rest period, his hearing ability should improve, according to Xiaoqinga.
Reverse tilt loss is usually inherited and is related to conditions such as Wolfram syndrome, which affects diabetic patients, or Mondini dysplasia, which affects the cochlea, internal part of the ear close to the auditory nerve.
Hearing loss generally affects hearing loss. first the high-pitched sounds, which begin to be perceived more gently or stop being completely heard.
This hearing loss may also be caused in some cases by a change in pressure in the inner ear fluid or by an abnormal opening in that organ – as a side effect of general anesthesia for example
People with hearing loss on an inverted slope may have difficulty hearing voice over the phone or noise from the motor.
Diagnosis is difficult because, in general, except in times of stress where hearing loss worsens, people who suffer from it do not realize that they hear low frequency sounds differently from people having a normal hearing.
