Earlier this year after Thanksgiving, a couple researchers in Finland stated that children's amount of music in their lives is connected with their impaired hearing. Researchers studied children with impaired hearing and measured various components related to noise in their lives. They discovered that children who use devices or implants to hear better have a better perception of noise if they sing daily, compared to children in the same category who don't sing or are not exposed to music in their day to day lives.
Personally, I think that music should be implemented more frequently amongst children with hearing difficulties for their own positive development and understanding of the world around them. Not only will it benefit their auditory skills, but it will benefit their overall health, and it can teach them about various cultures in the world.
