Waking up with Rare Hearing Loss

When a woman wakes up one morning and can’t hear the voices of men — well, the jokes kind of write themselves. Wouldn’t it be great to have that switch?

But for a Chinese woman in Xiamen that this happened to recently, it was a case of reverse-sloping hearing loss — and no doubt did not feel like a joke. Nor for anyone who comes down with this rare condition.

Most hearing loss starts at the high end of the sound spectrum. That’s how it works for the vast majority of people and there is a common graph — the ski slope hearing loss curve — that is produced when a hearing test is charted.

Reverse-sloping hearing loss has the opposite curve.

After her ears started ringing (tinnitus) and she vomited the night before, the woman woke up and realized that she had experienced a form of sudden hearing loss. She could no longer hear her boyfriend when he spoke to her. A trip to the emergency room — and luckily a female doctor — quickly confirmed that her hearing was gone in the part of the spectrum where most male voices reside (she couldn’t hear the man sharing her hospital room either).

The condition is very rare — only 3,000 cases are reported annually in the United States — and can be dangerous, since automobile engines and other machinery produce sound in the same part of the sound range.

Eventually, it was determined that stress was the likely cause, aggravated by working late and not getting enough sleep. It should be noted that the role stress can play in hearing issues is often not fully realized.
