Public health agency the US Food and Drug Administration announced on Friday that it has approved the marketing of the new Bose Hearing Aid device intended to amplify sounds for individuals 18 years or older with perceived mild to moderate hearing impairment (hearing loss), which can be caused by ageing, exposure to loud noises, certain medical conditions and other factors.
The FDA bill also included the bipartisan Over-the-Counter Hearing Aid Act of 2017, which would make certain types of hearing aids available over the counter to Granite Staters and Americans with mild to moderate hearing impairment.

The hearing impairment definitions are based on unaided thresholds (i.e., thresholds obtained without a hearing aid); therefore, a moderate hearing impairment or worse in the better ear (i.e., >40 dB HL PTA) was chosen, because individuals with this degree of hearing impairment would likely have considerable listening difficulties in most situations without the use of amplification devices.
In fact, the National Center for Health Statistics estimated that 95 out of 1,000 people have at least a moderate hearing impairment. While most of these people can actually hear an amplified ring, there is a percentage of those who cannot.
