As many as 4 out of every 1,000 infants born today have permanent hearing loss. When parents learn that their child has hearing loss, they are faced with many difficult decisions. These decisions can include choosing therapies and schools, as well as finding financial help for hearing aids or cochlear implants (人工耳蜗). Help Me Hear Foundation is a public charity that gives the gift of hearing to deaf children from families existing on very low incomes around the world. The foundation offers life-changing services for impoverished families, and provides real help for children with hearing impairment who may otherwise be left behind in schools or society due to their lack of hearing.

Help Me Hear Foundation believes that a child’s first years of development are critical. Being able to hear is vital to human, and Help Me Hear Foundation seeks to provide a positive lasting impression on society through its programs. Help Me Hear Foundation has many goals, including relieving the burden on communities with hearing-impaired infants and children, and strengthening the social structure of families and neighborhoods.

Recipients of Help Me Hear Foundation’s benefits receive state-of-the-art hearing devices that otherwise would cost thousands of dollars per child over the course of their lifetime. The Foundation raises money through donations for hearing aids and cochlear implants, which saves recipients and their families on average over $50,000 on related expenses.

The Foundation tries to be a transparent charity, and wants to be a catalyst for allowing deaf and hearing-impaired children to develop in a typical fashion alongside their peers.

Needy families can obtain information on specific services, and find out about deafness education by visiting the Help Me Hear Foundation’s website. The website offers helpful information on how hearing aids work, and how hearing aids ease many of the learning and language challenges that hearing-impaired children deal with on a daily basis.
