People hear different things at different times, so our acoustic environment is completely different. A new era will bring new sounds, but the difference in quality and intensity will also hurt people. Noise pollution is a worldwide problem. Sound will affect our behavior and even change our behavior. For example, music was created and adapted by human beings to reflect their own feelings, and then spread to influence others. Reading is another important way to spread knowledge. Unlike pictures, sound is more permeable and infectious, giving people an instant view of the environment.
