Many people with hearing loss experience barriers to hearing sounds that they need to respond to immediately.

For example, when any of these sounds occur in your space: fire alarm, smoke alarm, security alarm, civic alarm, running water, door knock, pet noise, or baby cry, record and share the 10 seconds sound clip with us. No fart sounds or any other weird sounds, please. For those sounds, we love to continue to it tune out! "Friends, Romans, countrymen, lend me your ears." - Julius Caesar. (William Shakespeare) Why should you record and contribute? * Everyone deserves equal access to information. Our society prefers people with hearing. By recording sounds in real time from your smartphone, you give people with hearing loss a chance for equal access. * You can help someone out. Not everyone has the privilege to hear, and sharing your strength is a feel-good thing. * It's the right thing to do.
