Japan firms develop earphones, test van for hearing support

Japanese companies have intensified efforts to help individuals with hearing impairments, recognizing that the issue now affects younger generations. Casio Computer Co. unveiled the earU, a wireless ear-cuff device designed to aid those with hearing difficulties but not requiring hearing aids. The earU digitally enhances human voices for a more natural sound and assists users in pinpointing speaker locations and distances.

Wearing the device is comfortable, unobtrusive, and suitable for extended use. A survey by Casio revealed that around 35% of people aged 45-69 struggle with clear conversation hearing. The company aims to create a stylish product with interchangeable accessories, particularly appealing to women. Meanwhile, nonlife insurer Sompo Japan Insurance collaborated with entities like a hearing aid organization and automotive company to create a mobile hearing test vehicle.

The Toyota Hiace-based van, featuring advanced soundproofing, enables staff to conduct accurate hearing tests and adjust hearing aids remotely. The vehicle allows users to consult doctors online, aiding those in remote areas or mountainous regions. Demonstration tests commenced in April, with plans to commercialize the service following user and stakeholder feedback.

Convenience store operator FamilyMart introduced communication boards at its outlets, enabling customers and staff to communicate using pointing gestures. The store's payment app, FamiPay, includes an ear icon button for users with hearing impairments. Other convenience stores, such as Seven-Eleven Japan and Lawson, offer similar services using pointing-based communication boards.

These initiatives follow concerns that excessive headphone use poses risks to younger people's hearing health.
