Amazon has patented modern headphones that can theoretically save lives. The noise reduction technology installed in them is equipped with a music off mechanism when a certain type of sound is emitted at a selected frequency.
Built-in noise canceling technology is very useful as it eliminates background noise, allowing you to focus entirely on the music. Unfortunately, it is also dangerous because the user does not hear the ambient sounds. Maybe then fall under the car when riding a bike or not hear the person calling for help.
Amazon has patented a solution that can potentially save lives. The company patented a technology that automatically turns off the music when built-in microphones detect the sound of a certain frequency. It may be a scream, or even a specific phrase, eg a name. The headset at this point will immediately hear what’s going on around him and he will be able to respond to the situation right away.
