A person with normal hearing doesn’t think for a second when walking from a crowded city street into a quiet office.Those with hearing aids, however, must constantly adjust their devices to match the current sound situation, unless they have hearing aids that auto-adapt.
Advancements in technology harness the benefits of three-dimensional (3D) printing to make ear molds that fit snugly and correctly into the ear. With 3D printing, the current hearing aid fitting process may some day be completely eliminated.
If you think you need hearing aids, you might need to hurry up and get some. According to the World Health Organization’s fact sheet on deafness and hearing loss, updated this month, the current production of hearing aids only meets 10 percent of global needs.
