Sound bars are designed to reproduce audio in three dimensions. This allows the user to hear dialogue more clearly. In addition to this, most sound bars include a technology that prevents the volume of commercials from being louder than the soundtrack of the show. Other sound bars have a “late-night” mode, which reduces the volume of television programs so as not to disturb sleeping neighbors. This is a popular feature, but it may cost you extra money.
