According to the World Health Organization (WHO), approximately 5% of the world’s population is affected by disabling hearing loss. In the US alone, it is estimated that 35 million people have some level of hearing loss, but only 28% of that population has a hearing aid. Many people in the developed world have expressed that they avoid using a hearing aid because of how they look, the difficulty there is in tuning them, and frustration with time and money spent buying and replacing batteries.
These frustrations are not confined to the United States, and have led an Australian research team to develop a device called Facett which should help to eliminate some of the barriers that people face when deciding whether or not to use a hearing aid, as Elaine Saunders, Adjunct Professor at Swinburne University of Technology and co-developer of the device, explained:
“This is a huge leap in progress for the four million Australians suffering hearing loss, many of whom aren’t using hearing aids because of appearance, repeated and frustrating visits to suppliers for hearing aid tuning and the inconvenience and complexity of changing batteries. Facett is a true collaboration between science and design. It’s part of a digital health system that empowers people to self-manage their hearing experience.”

“I provided multiple designs for the modular connections, each of which provided different features aimed at improving the strength of the connection between modules without making the hearing aid too difficult to manipulate. The design and prototyping process was carried out in rapid iterations using a combination of computer-aided design software and various types of 3D printing.”
This device should go a long way toward eliminating the barriers to using a hearing aid for those who could benefit from the technology, as Swinburne continues to devote resources to advances.
3D printing has enabled many innovations in hearing aid technology, in both prototyping and production, and this latest device serves as another example of the speed and efficiency possible to benefit those with hearing loss, as the bulk of the hearing aid industry has turned to additive manufacturing.
