166 An Excursus into Hearing Loss

**Index of technical terms**

slow down hearing loss and lead to a healthier society.

To avoid advanced hearing loss and instances of hearing loss-related dementia, it is important to recognize hearing loss at an early stage and provide treatment that prevents the loss of haircell or auditory-nerve stimulation. In particular, for those who wear hearing aids in only one ear, speech intelligibility is known to degrade more in the other ear [50, 51]. However, currently popular implanted hearing devices are a fairly large burden for people soon after they become aware of their hearing loss. For this reason, we tend to stick to wearable hearing aids that are easy to be put on and take off. Researches are therefore using the scientific method to remove technical barriers for hearing aids. Further, governments should try to remove other barriers by providing services such as financial support or public qualification for handling hearing aids, and companies that make hearing aids should charge less money. This will help
