Be careful when being fooled by "Dolby" Certification

Dolby is a British R. m. dr. Dolby's Chinese interpreter, who has established the Dolby laboratory in the United States, has successively invented many technologies such as the Dolby noise reduction system and the Dolby surround sound system, which have a huge impact on movie and home audio. The commonly used Dolby technologies in the family mainly include Dolby noise reduction systems and Dolby surround sound systems.

The Dolby lab was established by dr. R. Hamilton Dolby.

Dolby has two certifications: Dolby cinema and Dolby standard audio room.

Both the "Dolby cinema" certification and the "Dolby standard audio room" certification are aimed at improving sound effects. To put it bluntly, they are provided to users.Dolby Surround Sound"(The popular point is the virtual surround sound effect), not how much the sound quality is improved, nor how good the sound quality of the product with Dolby certification is promoted by dealers or manufacturers, therefore, when purchasing a notebook, you must first find out what Dolby is.

The sound quality of a speaker depends largely on the size of the Cabinet and the size of the speaker unit. In other words, the built-in speaker in the notebook is too small, inherent defects are doomed to make it difficult to deliver excellent sound quality, of course, this is also determined by the inherent conditions of the notebook, because the use of the notebook is "mobile", to meet the needs of users to move, the built-in Speaker of the notebook can only meet the user's"Basic listening requirements".

With Dolby certification, can you experience surround sound effects? The answer is not certain. People who know about the home theater know that the true effect of 5.1 and 7.1 must be properly placed on speakers, at present, the certification provided by laptops only provides the virtual surround effect, not the real effect provided by 5.1 and 7.1 cinemas.
