With the growing popularity of large screen TVs and the continuous addition of new OTT (over-the-top) services, more and more users are looking to establish a movie theater experience in their homes. On top of that, social distancing measures have forced people to go out less, stoking their desire to enjoy premium visual and audio experiences from home.

Full, clear and deep sound plays a crucial role in ensuring that content is delivered as it was originally intended. Paving the way for new audio experiences, Samsung Electronics introduced its high-end soundbar models, the HW-Q950A and HW-Q900A, in May this year. The new top-of-the-range models take sound quality to the next level with up to 16 channels and a host of improved features that bring even greater satisfaction to users. Samsung Newsroom sat down with the product experts of the 2021 soundbar models to uncover the secret to their powerful and precise sound.

11.1.4-channel surround sound that fills the room

Thanks to our constantly evolving culture of content, the sound becomes richer, more complete and more expressive. The days of one-way (mono) sound are long gone as we ushered in the era of multi-directional channels that allow sound to fill the surrounding space. “Sound is becoming more and more important as people now watch a wide variety of programs that place more emphasis on audio quality, such as music shows and movies.” Said Haekwang Park, senior engineer in the sound lab at Samsung’s visual display company.

To meet the increased expectations of consumers, Samsung has spared no effort to develop high quality sound bar products that deliver very realistic sound. In 2016, Samsung released its first 5.1.4 channel sound bar model. This soundbar was equipped with left, right and center channels, two rear channels, a subwoofer and four up-facing speakers, and delivered immersive three-dimensional surround sound. Other channels were added to later models, including a surround channel on the side of the soundbar and a wide surround channel to deliver sound to the front and sides. In 2020, Samsung introduced a 9.1.4-channel model.


In 2021, Samsung took it a step further with its latest 11.1.4-channel model, the HW-Q950A, which features two surround back channels. Product planner Mingyo Oh explained that, “The newly added channels are located on the sides of the surround back speakers. They add liveliness to dynamic scenes involving things like airplanes in flight and car chases by allowing sound to hit the sidewalls before bouncing back to where the audience is positioned. The premium soundbar delivers an exceptional audio experience by filling previously quiet moments with powerful and immersive sound.

Deliver sound exactly as intended with advanced rendering and waveguide techniques

A channel is a passage for sound that dictates the direction in which it travels. This is why having more channels provides better and smoother sound. It usually requires expensive equipment to deliver 11.1.4 channel sound, but Samsung’s HW-Q950A is capable of delivering a stunning 3D surround sound experience with just four speakers thanks to its rendering and guide techniques. unsurpassed waves.

Rendering is the process of creating a way for the audio output to deliver sound exactly as the artist intended. The developers at Samsung have made it possible to provide an optimal acoustic experience with the soundbar system by exploiting its advanced rendering technology. “To provide the most natural audio experience for users, we have carefully designed our products to deliver sound seamlessly. The HW-Q950A sound bar delivers sound that reflects in different directions and reaches users’ ears at the optimum angle, ”explained Shinhye Choi.

Advanced waveguide technique is also a must when it comes to delivering next level sound. A multi-channel speaker emits sound in multiple directions, and the waveguide technique allows speaker components to deliver sound in the direction intended by the developer. Haekwang Park said, “Leading experts from Visual Display Business Sound Lab and Samsung Audio Lab in California came together to design the parts that went into the speakers. Our sound bar models are meticulously constructed to deliver world class sound performance. “

How SpaceFit Sound + further improves the viewing experience

When a speaker is emitting sound in the room, the first to reach the listener is direct sound. But soon after, reflections from the walls, floor and ceiling reach the listener’s ears. Room surfaces can reflect or absorb sound, which is why the same sound is heard differently depending on the size and layout of the viewing environment. Samsung’s HW-Q950A soundbar and 2021 TV models deliver stunning sound that adapts to users’ viewing environments by analyzing the dimensions of the space they are in using SpaceFit Sound +.

SpaceFit Sound + combines SpaceFit Sound technology, which provides optimized sound, and Auto EQ (automatic equalizer) technology built into the subwoofer. AutoEQ technology was invented by Dr. Adrian Celestinos at Samsung’s Audio Lab in California. Adrian and his teammates, Jin Yoo, Ritesh Banka and Glenn Kubota worked closely with the HQ team to deliver this breakthrough technology that calculates the average response in the listening room at low frequencies, then reduces the most peaks. important. The result is deep, clean bass with less boom and ringing. Together, the SpaceFit Sound + and Auto EQ solutions use built-in microphones to take an in-depth look at the viewing space, then feed that data to the soundbar to enable it to deliver a tailored sound experience.

Combining truly rich sound with very practical features

As with the other models, Samsung has focused on creating a new level of acoustic immersion with the HW-Q950A. But that doesn’t mean that it can’t include a host of handy features as well. For starters, the Active Voice Amplifier (AVA) function clarifies dialogue in viewers’ favorite shows to help them clearly hear on-screen conversations amid a variety of background noises. With a built-in microphone, the soundbar automatically measures noise levels and improves voices if the noise persists for more than three seconds or exceeds a certain threshold.

And the HW-Q950A optimizes the sound for various types of scenes, such as those with loud sound effects and scenes rich in dialogue. For example, the Adaptive Sound feature analyzes sound signals to provide the optimal sound experience for each scene. Additionally, Game Mode Pro delivers a powerful and immersive gaming experience with upward-facing subwoofers and speakers. The Tap Sound feature also allows users to simply tap their smartphone on the sound bar when listening to a song to take their listening experience to the next level.

The motto of Samsung soundbar developers is to master the basics of sound. “We are working our best to deliver the highest quality sound,” explained the developers. “We do this by working closely with groups of experts and using Samsung’s advanced measurement and simulation techniques to set clear standards for what we define as ‘best’ sound.

The ultimate goal of developers is to deliver a top-notch acoustic experience to users, regardless of the type of content they consume or the specific characteristics of their viewing environment. Let’s keep our fingers crossed that they make this dream come true.
