Emergency warning systems must make all information accessible to people who are deaf or hard of hearing -- it is federal, state, and local law. The best way to protect yourself in the event of an emergency, such as a natural disaster or an industrial crisis, is to ensure that you will receive detailed warning information in a timely fashion.
We won the war, but many veterans lost their hearing. Many sailors, marines, and airmen are inducted into service with excellent hearing and return with a range of hearing challenges. While most people lose their hearing gradually over several years, veterans are regularly exposed to instances that can cause damage to hearing.
