How to distinguish between subjective and objective sound?

1.Frequency response. The frequency that can be heard by the human ear is 20-20000Hz.

Ordinary speakers 100-16000Hz is already very good. Audiophiles have 20-20,000. In short, the closer to 20-20000, the better.

2.Distortion rate. It should be less than 3%, of course, the smaller the better, there are the following.

3.Looking at the frequency response curve, in the audio range, the smoother the better. There should be no significant peaks or troughs (worse speaker manufacturers don't offer curves).

4.Weight. The heavier the speaker with the same volume of power, the better.

5.Horn paper cone, ordinary paper is poor, and the material with high hardness is better. 6.

The speaker voice coil is better made of oxygen-free copper. 7.Different brands of speakers have different styles,Good at performing different **,This can not be seen from technical indicators,Choose according to experience or introduction。

For example, the low frequency to 80Hz is more expensive than 100Hz, but 40Hz is much more expensive than 50Hz. The closer you get to the highs, the more ****.

In film and television art, the audience, as the listener of the sound, may listen from the perspective of a third party or from the perspective of the first person, which means that the audience's auditory experience is equivalent to the auditory experience of the character, and the sound effect is subjective sound.

Look at the frequency response of the speaker, and you will know the sound quality.

For example, a bookshelf box has a frequency response:

50hz-22khz

This speaker has a bass of only 50 Hz and a maximum of 22 kilohertz.

The bass of this speaker is average,The treble is also average,It's not HiFi sound quality(Because there is no +—3db),The frequency response error is large,It's not HiFi sound quality。 This speaker** is not expensive, you can get it.

Another speaker frequency response:

38Hz-22KHz (+3DB), this speaker from 38Hz subwoofer to a maximum of 22 kilohertz, frequency response error plus or minus 3 decibels, high resolution, is HiFi sound quality. The bass has a super bass, or HIFI sound quality, ** about 6,000 yuan.

It should be noted that,The parameters of brand-name speakers are real and reliable,The parameters of miscellaneous speakers may be fake。

A lot of the frequency response of Mabo computer audio is a false bass parameter, so it's just a miscellaneous brand, but it's about the same quality as the Edifier, but the false parameters are not good.

First of all, it is clear that objectivity is relatively subjective, subjective, the main represents oneself, and the view represents the observation of concepts and feelings, that is, everything in one's inner world, which is collectively called subjective, and everything outside one's inner world is collectively called objective.

So, to distinguish the objective is to be outside the inner world. Everything outside the inner world is influenced by objectivity.

Even if you have your own opinion, sometimes you have an objective view. For example, if you look at a problem from someone else's point of view, you have a strong sense of objectivity, but it is not an objective influence.

Objective influence, that is, objective things, produce feelings or consequences in the subjective world, this is objective influence!

It is all the influence except human will, for example, if you want to go to the park to play basketball today, this is a subjective will, but it rains heavily, you don't make it, "heavy rain" is an objective impact.

Fart, that's an objective sound.

Sound quality evaluation is divided into subjective evaluation and objective evaluation.

The objective evaluation is expressed by technical indicators, the traditional indicators have frequency response, harmonic distortion, signal-to-noise ratio 3, high-fidelity indicators also have transient response, intermodulation distortion, transient intermodulation distortion, etc., can be tested one by one, accurate comparison.

There is no accurate and quantifiable criterion for subjective evaluation, and the same literary terms to describe sound quality will be understood differently (e.g., the British sound is warm, the American sound is cold?). And there will be a lot of personal hobbies in the evaluation, and there will be a lot of disagreement. But since sound is ultimately appreciated, the highest final evaluation is still subjective.

So whether a speaker is good or bad, as long as you listen to it yourself and like it.

And professional affirmations can't be compared! Professional manufacturing requires very professional tools, inspection equipment, and you can listen to it with your ears, and the speaker is almost good. If you listen to it, you don't have to be too serious if you don't have high requirements, and you must be better than a hundred or less!

It is also related to the power amplifier sound source. The speaker should look at the frequency response, phase, propulsion distortion, etc., and the audio amplifier should be matched.

I don't know how many ** teachers in my country understand audio! Real sound engineers and sound engineers are with the sound every day, and their views are still a bit instructive. There is also one of the biggest differences between home speakers and professional speakers:

Professionalism should be strong, spread far! The sound of the home is beautiful. That is, in terms of sound quality, the best professional box is far inferior to the mid-range home speaker!

As long as you are satisfied with what you hear, there is no need to pursue high fidelity and high level too much. Theoretically, it is not necessarily possible to do professional data.

It's good to listen to. Some people have heard of very good equipment, but they don't think it works after a little clicking. Some people haven't heard of a good one, and 50 speakers think the effect is good.

Do you say it's a **teacher? Not a tuner?

If the teacher can't guarantee how much he says, but if it's a tuner, it is necessary to listen to opinions with an open mind.

The realm that audiophiles want to achieve is to restore digital (CD**) sound to real sound.

There is no clear standard here, and it requires the opportunity to see the recording environment in the studio in addition to talent (and generally not to look at it).

There are two speakers on the speaker, generally a tweeter and a mid-woofer. The role of a small horn is that of a tweeter. It is not necessarily that the larger the speaker, the more power is consumed, but the larger the speaker, the more power the medium and low woofer is used. How to judge the quality of the sound.

The tweeter is the tweeter unit in the speaker, and its function is to reproduce the high-frequency signal output from the crossover (the frequency range is generally 1000Hz-20000Hz).

A woofer is a type of loudspeaker, which is a transducer that converts electronic signals into sound. The woofer is composed of an electromagnet, a coil, and a horn film, and together with the tweeter and the midrange speaker, it constitutes the car audio.

1: Why use two horns? Because of the current ** (tape.

FM stereo radio, etc.) are all two-channel stereo**. That is, two speakers can emit different sounds at the same time. For example, when you watch karaoke discs.

Isn't it just that there is ** on one side. Is it a person singing on one side? That's binaural stereo!

2: Why are there two small horns? Here's where the profession comes in.

These two small horns are tweeters. Let's put it in layman's terms: that's when you listen to **.

There was the sound of a gong striking, "Bang." Cha. That's what came out of here.

And below the two large-caliber horns. It's a woofer. There is a drum beating "dong."

Boom. That's what came out of here. Most speakers have a crossover inside.

The required frequency of the speaker can be divided. Make each horn work in its own frequency range. So you listen more thoroughly.

Solid. Intoxicating you!!

3: Generally speaking, the larger the volume of the speaker. The power of the amplifier (W) required should be large. Large speakers for commercial use cost hundreds of watts. The home ones are much smaller. Small amplifiers can also be brought up with large speakers. But only vocalization. You can't have a "fever".

4: Judge the quality of the sound. Also very professional.

You're looking for someone who understands electronics. And you go to buy. Cutting corners today.

It's hard for me to describe it in a "few words". But you can find a CD you like and listen to it on the stereo!! Isn't it clear?

Lots of detail? Plenty of treble. If yes!

Congratulations. You've found a speaker you like!

Multiple speakers can use crossovers to form speakers according to the size and frequency characteristics, because the speakers in many speakers use multiple speakers to form high, medium and low tones through crossovers, so that only a good amplifier is needed to push. Of course, if there is a multi-channel sound source, you can also use two amplifiers to form a 4-channel sound.

The frequency characteristics and overall equalization of the loudspeaker.

Like any other audio device, the ideal speaker should be neutral, unobtrusive, unobtrusive, and should not have its "own" sound, but in reality such speakers do not exist. What we wanted was a pair of speakers with a wide frequency response range and good overall balance, i.e. approximately the same loudness for reproduction across bands, without overstating the bass in one section. Some speakers have a high-pitched treble that sounds harsh, while others have exaggerated bass that sounds muffled.

In particular, some cheap speakers deliberately exaggerate a certain frequency when designing, so that people can listen to it very "ear-grabbing", which is easy to impress people and attract the attention of buyers. Especially people who don't know much about speakers and speakers. In fact, this is an abnormal sound coloration, and it can make people feel tired after listening to it for a long time.

The speaker with good overall balance is very durable, listen to it for a long time, and the more you listen to it, the better it sounds. It gives people a sense of pleasure and harmony. Whether the so-called sound is "good" and whether it is rich in "** taste" depends largely on the overall balance characteristics of the speaker's timbre.

Low-frequency control.

If you prefer to listen to a richer acoustic component**, then special attention should be paid to the speaker's low-frequency performance, on the one hand, we want the low-frequency response to extend down to the lower frequencies. On the other hand, good low-frequency control is also desired. A speaker with good low-frequency control, with a sturdy, vertical, and elastic bass; Conversely, it sounds like the bass is loose and not solid enough.

If you value bass reproduction, you may want to bring a bass-rich CD with you to listen to it.

Transient response. Transient response refers to the ability of the speaker to follow the sudden rise and change of the pulse in the ** signal, or the speed of response, therefore, the transient characteristic is also often called the sense of speed. The speaker with good transient characteristics has good detail reproduction ability, rich sense of layering, clear and transparent sound, free retraction and playback, and strong sound; On the contrary, the sound sounds muddy, with poor detail and layering, and the mud and water lack strength.

A good way to judge the transient characteristics is to listen to a solo piano piece, because the piano's signal wave formation front is very close to the pulse signal. If you hear the piano sound clear and transparent from the speaker, and the short notes that jump into the braid, you can see that this is a good indication of the transient nature of the speaker.

A speaker or speaker, first of all, it is divided into a full set and a mix;

The general quality of the full set is guaranteed, but it is expensive; Mixing and matching is prone to all kinds of sound quality and line problems;

Putting aside the essential difference between a full set and a mix, to appreciate a good speaker (sound) words:

First, the overall sound is normal, including the power amplifier, speaker, speaker size, etc., and the sound should be standard;

The second timbre is pure and free of noise (current, high and low frequency collocation is not accurate, etc.), the third sound expression is dynamic and accurate, and the expression of each instrument, vocals, reverberation, etc. is clear and accurate;

Fourth, each brand of CD, gall machine (sound source), power amplifier, speaker (including speaker), output and cable, will have their own sound characteristics, need to be carefully tasted and accumulated.

Look at your sound source,First of all,MM1 is very poor in listening to such a box,Secondly,MM1 is HIFI,Bose's advantage is that it is small volume and heavy bass,If you listen to rock, then Bose is good,You listen to a female voice,At the price below the desktop5000, Cas-1 can win MM1,Bose's C2 C20 mm C5 is not playing,MM1,Cas-1,C2,Miaoyun 4 I have it。

Bowers & Wilkins MM-1 has been discontinued, and it was from 2011, when the sound level was not very high. It's really not easy to find a cheap and functional sound. Bose Bluetooth foreign ** is a little more expensive

I'm now using the domestic Meidong e-group Bluetooth speaker is pretty good,It is said that their family is specialized in audio,It's just that they are mainly doing foreign markets,The quality doesn't need to be explained,Foreign requirements for quality are very high,The sound quality is also high。 However, a few days ago, I saw the news that they were going to enter the domestic market when they saw the news on their corporate Weibo, so that domestic users can also use high-quality, perfect sound sound...

There are many objective parameters to measure power amplifiers and speakers, but people's hearing is a very subjective thing. It's hard to say whether the indicators are good or bad just by looking at them.

The choice of these things depends on the purpose, financial ability, and personal preference for style.
