Imagine having a legitimate reason for not hearing your partner say, "Tonight, you're on dishes".
The night before, the patient-only identified by her last name Chen-heard ringing in her ears and vomited.
This isn't a selective hearing joke - Chen, from Xiamen in China, woke up one day and she was unable to hear her boyfriend when he spoke - or any men, as it turned out.
A Chinese woman's rare health condition has reportedly rendered her unable to hear the voices of males - including her own boyfriend.More news: BSPD welcomes children’s oral health reference in NHS Long Term Plan
"She was able to hear me when I spoke to her, but when a young male patient walked in, she couldn't hear him at all", Xiaoqing said.This condition renders patients unable to hear higher-pitched voices, like those of women and children.
Reverse-slope hearing loss can occur due to a lack of sleep or physical stress which Dr Xiaoqing believes is the case, but can also be due to genetics.
Anyone who suffers from low frequency hearing loss, generally, can't hear noises that have a frequency of 2,000 Hz or below. She expects Chen to experience a full recovery. In reverse-sloping hearing loss, the shape of the audiogram runs in the opposite direction. It can affect one in almost 13,000 patients with hearing problems.
As well as struggling to hear low-frequency voices, those with the condition can find it tough to make out voices on the phone, as well as noises like the hum of the fridge or thunder.More news: Nurse causes 'catastrophic injury to baby during delivery'
Low frequency hearing loss can be very risky for people as it can affect their ability to hear things like the low hum of an oncoming vehicle.
It is believed that genetics can cause this condition. Less often, a shift in the pressure of ear fluid can trigger reverse-sloping hearing loss. It can be caused by inner ear hair cells getting damaged. By 2050, that figure is expected to hit over 900 million.
The extremely unusual condition, which reportedly affects only about 3,000 people in the U.S. and Canada, causes patients to lose their ability to hear low-frequency sounds, including average male voices.More news: Bihar: Protests break out in Gaya after girl is found beheaded
