Remember all the times your parents might have told you not to blast the music so loud? Well, they are right. Surrounding yourself in a noisy environment could eventually lead to a loss of hearing over time, and can increase the possibility for other auditory loss symptoms.
Last week, a woman named Ms. Chen from China was diagnosed with a rare disease called reverse-slope hearing loss. As mentioned first on Daily Mail, she woke up one morning and was unable to hear her own boyfriend’s voice.
This condition affects only about 3,000 people in the U.S. and Canada and is a genetic condition that is unfortunately untreatable. This disease affected the fluid surrounding inner hair cells and was potentially triggered by a sudden viral infection.
The patient is unable to hear low-pitched voices and can only listen to women’s voices that are naturally higher pitched. Also, these patients are unable to hear vowels, which have a low pitch energy that our eardrums cannot perceive.
There is a slight hope if the ear, nose, throat (ENT) specialist could catch the condition overnight and provide a steroid injection, but most conditions are permanent. The patient revealed that she has been under large amounts of stress which may have caused it.
More Information on Reverse- Slope Hearing Loss (RSHL)
This hearing loss mostly affects low-frequency audible noises. It is caused by a dominant gene that affects the inner hair cells, which send messages from outside sounds to the brain.
Some symptoms include difficulty understanding speech and men’s volume. It is difficult to hear low tuned environmental noises such as the refrigerator humming. Many people who use a hearing aid utilize it to hear higher frequency noises, so it would not be an effective tool for people diagnosed with RSHL. People with this disorder require a different amplification so that they would need different settings.
This rare disease is difficult to treat because not many physicians have encountered this disorder. Although the symptoms are not severe, it is critical to hear low environmental noises, such as a car heading towards you.
There are some starting points to treat RSHL, such as using a digital, multichannel, nonlinear hearing aid. This would amplify lower frequency settings at a level that is comfortable for the patient.
