Music and the sound of communication are what we want to hear, but in many cases, some sounds are not what we want to hear. Such sounds are called noise, which can affect our daily lives, like the sound of cars driving on the road. However, noise can also be useful as long as we utilize it reasonably. For example, this sound energy converter can transform sound into energy, and then we can use it for anything, doesn't that feel amazing? The size of a single sound energy converter is 450*450*80mm, and its weight is 7 kilograms. It can convert each decibel of sound into 30 watts of energy. An airplane taking off generates about 140 decibels of sound, which could be converted into 240 kilowatts of energy through it. We don't know whether this sound energy converter is a conceptual product or scientifically feasible. If such a product could really come to market, it would be suitable to place these sound energy converters in places with a lot of noise, such as roads and airports. This would be an excellent way to utilize energy.
