Audiophiles chat, often hear them say high-level words such as sound quality, timbre, sound field, frequency band, resolution, and dynamic contrast. For beginner , who doesn't understand music or sound, he can hear it in a cloud of mist.
Now we will use simple and easy-to-understand words to show you the conceptual meaning of these words.
1. Sound quality
Sound quality refers to the quality of the sound, and sound quality refers to the quality of the sound. Many people confuse it with "timbre".
What is the quality of sound?
When you are talking about a pair of good quality shoes. You must mean fit, comfort, and durability, not that it’s good-looking or fashionable. Similarly, when you are talking about the sound quality of a mini portable speaker, you are not talking about its level and positioning, but specifically referring to this mini portable speaker. It's as if it's not durable or fit.
A mini portable speaker with good sound quality is comfortable and durable. You don’t have to explore the reasons why it sounds comfortable and hard to hear. That’s the business of the experts. You just need to judge with your ears.
Some mini portable speakers are vigorous, powerful, fast, and resolving, but they are not durable to listen to. That may be a sound quality problem. A good audio mini portable speaker should have a sound quality like a good voice, which makes people not greasy. Maybe I say that you still think it is very abstract. In fact, it is not, I can give another example to illustrate.
When you mentioned fabric, you would say: This material is of very good quality. When you are eating a steak, you will say: The quality of this steak is very good. When you are complimenting a child, you will say: This child is very qualified.
Therefore, when you are listening to an audio mini portable speaker or a musical instrument, you will also say: its sound quality is beautiful. From the above examples, you can clearly know that "quality" is innate nature. The sound quality is noble, very good, and beautiful, which means the nature of this mini portable speaker is very good, and it sounds very comfortable. It can be said that sound quality is the most important part of the audio mini portable speaker.
2. Tone
Tone color refers to the color of the sound.
We often hear the saying that the sound of this violin is really cold, the sound of this violin is really warm, etc. This refers to the sound of the violin.
Sound is like light, it has color, but it is not seen with the eyes, but heard with the ears. Generally, the warmer the tone, the softer the sound; the colder the tone, the harder the sound. Too soft or too hard is of course not very good. Sometimes, timbre can also be described by words such as "noble" and "beautiful". Basically, it is also one of nature.
However, just like cloth, cloth quality refers to its material, and cloth color refers to its color. There are still clear boundaries between them. In the comments of the audio mini portable speaker, the tone is like the color, which refers to its unique color.
The tone of some mini portable speakers is yellowish, some white, some cold, and you can even say it is blue with a little sadness. In short, an audio mini portable speaker is like a musical instrument, almost inseparable from the fact that the more expensive the sound, the more beautiful it is. A two-million-dollar violin may have a beautiful golden timbre, while a five-thousand-dollar violin may look like a faded painting.
Although everyone has different opinions, "beauty" still has a "consensus" that everyone recognizes. You can't say that a person with an upturned nose is the "incarnation of beauty"; you can't say that a mini portable speaker with a cool blue tone is the same. nice.
This is our consensus on the beauty of sound.
3. frequency band
Frequency band refers to the sound frequency. The human ear's perception of sound frequency is from the lowest 20Hz to the highest 20KHz, while the human voice frequency range is concentrated between 80Hz-12kHz. The sound of different frequency bands has different feelings to people of.
For the 20Hz-60Hz part, this boost can give the music a powerful feeling, giving people a very loud feeling, like thunder. If the boost is too high, it will be turbid and unclear, resulting in poor clarity, especially for audio equipment with poor low-frequency response and heavy low-frequency.
The 60Hz-250Hz section is the low-frequency structure of music. They contain the basic sound of the rhythm part, including the fundamental sound and the tonic sound of the rhythm sound. The ratio between it and the high-mid tone constitutes the balance of the tone structure. Boosting this section can make the sound fuller. Excessive boosting will make a rumble sound. Attenuating this frequency band and high-mid band will make the sound thin.
The 250Hz-4KHz section contains the low-frequency harmonics of most musical instruments, and affects the clarity of human voices and musical instruments. The adjustment should be made in line with the previous bass settings, otherwise the sound quality will become very dull. If you raise too much, the sound will look like the sound on the phone; if you raise 600Hz and 1kHz too much, the sound will look like a speaker; if you raise 3KHz too much, it will mask the recognition sound of speaking; if you raise 1kHz and 3kHz too much, it will The sound is metallic. Since the human ear is more sensitive to this frequency band, it is usually not adjusted for this section. Excessive raising of this section will cause hearing fatigue.
4KHz-5KHz part, this is the frequency band that affects the sense of presence (distance). Increasing this frequency band makes people feel that the distance between the sound source and the listener is a little closer; attenuation will make the sound distance feel farther.
6KHz-16KHz, this frequency band controls the brightness, macro brightness and clarity of the tone. Generally speaking, boosting this part makes the sound loud, but not clear, and may also cause excessive tooth tone; attenuating this part makes the sound clear, but the sound quality is slightly thin.
