Other devices support Sound Notifications as well, including Wear OS devices.
First Apple and now Google, have added the sound recognition feature that allows smartphones to detect certain sounds around you and trigger a notification for you. Google's Operating System- Android has been the most adopted mobile OS for nearly all mobile companies, except, of course, Apple. The way this feature works is that your phone's microphone listens in and detects any specific sounds that you may have chosen, and sends you alerts that these have been heard in the vicinity. It'll also give you tips like keeping your phone in the middle of the room if you want the sounds detected there.
The trend of lightweight apps that are going to help users utilize a service that they are interested in without clogging up their phone with heavy file sizes is still ongoing, and the latest entrant into this trend happens to be Gmail. Sound Notifications works with other compatible devices too, including Google's Wear OS. That way, you can continue to get alerts about critical sounds even when you are asleep-a concern shared by many in the deaf and hard of hearing community. Turn on the new function via Settings Accessibility Sound Notifications.
Users can also scroll through a Timeline view to see notifications from the past few hours about sounds they may have missed, showing when the sound occurred and how long it was.
Apple's version can identify a few more sounds, including vehicle horns and cats meowing. If a person is deaf or hard of hearing and imagine that someone is ringing a doorbell, the phone will notify the person about the ringing bell at the door. While they can certainly do all of those things, they're also invaluable tools for a lot of people.
