Dolby Headphone technology allows you to enjoy multi-channel programs with traditional stereo headphones, such as Dolby Digital or Dolby Surround movie programs, you can feel the shock and true surround Sound effects. You can also get more natural sound effects when listening to stereo programs like CDs and MP3s. For any type of program, you can enjoy it for a long time without fatigue. Dolby Headphones are signal processing systems that enable your stereo headphones to realistically simulate the sound produced by a five-speaker playback system. When using Dolby headphones to listen to programs, the sounds that were originally presented in front of you will appear in front of you, and the sounds that were originally presented in front of you will also appear around you. These sounds will no longer be concentrated in the center of your brain. In fact, Dolby Headphone technology can be applied to almost all products equipped with headphone jacks-such as audio products, video products or video game products, you can identify whether Dolby headset is applied to the product through the Dolby Headphone logo Than headset technology. <一> Speakers and headphones When the sound from each speaker of a stereo system reaches your inner ear, it contains a whole set of spatial information, which are generated by the architectural acoustic conditions of the room and the physiological characteristics of your head and outer ear, respectively. This information enables your brain to locate the sound and embody it as a sound field concept, as if it can arrange the performer in front of you, just like in a concert. (See Figure 1) figure 1 Headphones send sound directly into your ears, without any spatial information like speaker playback. The result is an unnatural linear sound field between your ears. Figure 2 Traditional headphones listening The left and right sound images appear directly beside you, while the middle sound image appears in your head. This "in-brain" effect is unreal and causes listener fatigue. It has been extremely difficult to portray convincing two-channel stereo through headphones-it is even more challenging for the surround sound that usually requires five speakers to restore the program. The multi-speaker home theater system not only arranges the stereo image in front of you like a stereo system, but also integrates you into the sound atmosphere, giving you a shocking feeling of being "immersive" when watching movies and TV (see Figure 3) ). Figure 3 Multi-channel surround sound playback How Dolby headphones work When you are listening to a stereo or multi-channel home theater system, your ears will receive both direct sound from each speaker and multiple reflections from the room surface and furniture (see Figure 4). Figure 4 Mixture of direct sound from the speaker and room reflection This mixture of direct sound and reflected sound is different for each speaker in the system, depending on its position and your own position. When you reach your ears, the sound from each speaker has unique characteristics. The characteristics of all the channels together can make your brain feel such as the size of the room and the sound conditions, the location of the speaker, and the original signal. The spatial information contained in. Using powerful digital signal processing technology, Dolby headphones can add the original signal of each channel-two channels on a stereo program and up to five channels on a surround sound program-add features electronically, the feature It comes from a correspondingly placed speaker in a well-designed and excellent acoustic environment. In other words, Dolby headphones create up to five virtual speakers in a virtual room. The processor combines all these multi-channel signals containing the "features" of each channel into two coded channels, which means that when the signals of these two channels are sent to your ears through traditional stereo headphones Contains the sum of the features of direct and reflected sound from each virtual speaker (see Figure 5). Therefore, the auditory experience will be much more natural, and the sound seems to appear "out of the brain". Figure 5 Listening with Dolby headphones Up to 3 "listening room" parameter selection With its unique working method and powerful signal processing process, Dolby headphones have up to 3 different playback modes to simulate the acoustic characteristics of the corresponding real room: DH1 is a small room with good reverberation, and is suitable for the playback of movie and music recordings. It is the "reference room" for Dolby headphones and is available on all products with Dolby headphones. DH2 is a more "live" (or stronger reverb) room, especially suitable for music. DH3 is a larger room, more like a concert hall or movie theater. DH2 and DH3 are optional and not necessarily provided by some Dolby Headphone products. On those products that provide these three modes at the same time, you can easily switch between them to choose a mode suitable for a specific program type and your personal preferences. Other advantages Dolby headphones are suitable for all listeners; there is no need for personalization or user-specific adjustments. Like the speaker, the basic sound quality improves as the quality of the headset improves. But even some less expensive headphones can provide excellent Dolby headphones. Unlike listening with traditional headphones, you can use Dolby headphones for a long time. The natural externalization of the sound, and the elimination of echo, rendering and some other artificial effects, so that it can maximize the prevention of listener fatigue. You always occupy the "best listening seat in the room" because the sound effects you hear are independent of variable factors such as actual room sound conditions, speaker placement, and listening position. Applications of Dolby Headphones Dolby headphones are suitable for any stereo program resources, from CD to MP3 files, and also suitable for any multi-channel program resources, whether it is Dolby surround sound, Dolby Digital, PCM, MLP lossless compression or MPEG encoding. It can be built into almost all audio-visual products that can provide a stereo headset interface, including digital cable TV and satellite TV set-top boxes, VCR, DVD-VIDEO video player, DVD-AUDIO audio player, traditional and digital TV reception Computers, personal desktop computers, laptop computers, portable stereo equipment, game consoles, A / V surround decoders and receivers, car audio systems, and multimedia speaker systems. Multi-channel products with built-in Dolby headphone system to simulate multi-speaker surround playback, such as those A / V products with Dolby Digital 5.1 channel and / or Dolby Pro Logic / Dolby Pro Logic II decoding function, use Dolby Headphone (Dolby Headphone) logo. These products can also process Dolby headphones for stereo programs. Stereo products that use Dolby Headphone technology to simulate the playback of two speakers, use the Dolby Headphone Stereo stereo logo. All you need to do is plug in your favorite ordinary stereo headphones and sit in it, and you can enjoy the "best listening seat in the room".
