As an audio-visual gamer, I know that every detail of audio equipment is related to the ultimate sound quality experience. Among them, the degree of separation, which seems to be an inconspicuous but in fact crucial parameter, often seriously affects the quality of audio performance. Today, let's talk about the relationship between audio separation and audio equipment.
1. What is speaker separation?
Audio separation, in simple terms, refers to the ability of a speaker to maintain independence between the left and right channels when playing stereo music. In other words, when different sounds are played on the left and right channels, the speaker ensures that these sounds do not interfere with each other, so that the user can clearly hear the details and positioning in each channel. Separation not only enhances stereo sound, but also increases the width and positioning of the soundstage, allowing listeners to experience a more realistic and rich audio performance.
According to the International Electrotechnical Commission, stereo separation should be at least 40dB at 500Hz, but in my opinion, a resolution greater than 60dB is more ideal, and higher resolution means clearer sound quality and more accurate localization. The resolution is calculated as: Separation(dB) = 20 * log10 (Vmain/ Vleak), where Vmain represents the level of the signal in the main channel (e.g. signal from the left channel) and Vleak represents the level of the signal leaked into the other channel (e.g. leakage signal from the left channel in the right channel). This formula visually demonstrates the independence of the left and right channels when the speaker is played in stereo.
2. What is the function of resolution?
So why should we care about the separation of the speakers? Separation is an important part of the sound quality experience, and high resolution means that the speaker is able to accurately reproduce the sound of the left and right channels, allowing the listener to clearly perceive the position of different instruments or sound sources in the space. This precise sense of positioning is at the heart of the stereo experience, making the music sound more three-dimensional, realistic, as if you were in a concert.
When listening to a symphony, the separation of the sounds is especially important. For example, Beethoven's "Symphony of Destiny" has low separation, which is easy to confuse the voices of brass, strings, woodwinds and percussion instruments, affecting the layering of music. The high degree of separation can clearly show the position of each voice, such as the brass on the right, the percussion rhythm on the left, and the strings and woodwinds intertwined in the middle, making the music more three-dimensional and vivid, bringing a more shocking listening experience to the listener.
Good separation also helps to maintain the clarity and detail of the sound. In complex musical clips, high-resolution speakers are able to clearly distinguish between instruments and voices, rather than mixing them together. This allows for a better representation of the layering and dynamic range of the music, whether it is a soft melody or a strong rhythm, the high-resolution sound can be properly expressed. It also reduces crosstalk and maintains the independence of each channel. This allows the speaker to provide a purer, more natural and deeper sound experience when playing multi-channel music or movies.
The separation of the sound also plays a crucial role when watching movies and videos. A high-resolution sound system provides a more realistic surround sound experience, making the viewer feel like they are in the movie, enhancing the sense of immersion and presence.
As an audio-visual gamer, when choosing an audio bar, the first thing to focus on is the performance indicator of separation. After all, it's directly related to the clarity and layering of the speaker when playing. With a high standard of greater than 60dB resolution, we found the JEC HA-960D Dolby Atmos sound bar, which has an even better resolution of more than 80dB.
JEC HA-960D complete sound bar soundbar, including soundbar body, 2 surround speakers and 1 subwoofer. The 5.1.2-channel sound system covers the frequency range of 20Hz-20kHz that can be heard by the human ear, and it accurately separates the Dolby Atmos sound effects, whether it is the explosion sound common in action movies or the musical instrument performance in concerts, all of which give precise sound distinction, so that you feel as if you are in the scene, immersed in body and mind.
Separation, an important indicator of audio sound quality, should not be ignored when purchasing audio. Have you learned?
