A CMU study compares the effectiveness of self-fitted and professionally fitted hearing aids
A CMU researcher has found that professionally fitted hearing aids are more effective than those fitted by the user.
Dr. Yunfang Zheng, an associate professor at CMU’s Center for Communication Sciences and Disorders, said her research suggests people with mild to extreme hearing loss may still need to seek professional help to improve the effectiveness of their hearing aids.
“It's like eyeglasses,” Zheng said, “they can go to the store to buy their own glasses, right, if they need help they can get a better fit from the professionals, optometrists.”
Zheng said that professional fits provide a wider range of functions and those functions require professional knowledge.
The study comes as the FDA is considering allowing the sale of over-the-counter hearing aids.
