How to identify the sound quality of the speaker

Evaluation of the sound quality of speakers before or after the need to know:

In general there are two kinds of sound quality evaluation criteria, the first is the objective standard, that is, instrument beats headphones cheap testing standards; the second is the subjective evaluation criteria. Which is the object of the standard, High degree of clarity) "," vivid sense of music (speaker performance music more lively) "," good knot good (cohesion, positioning good) "," a sense of air (good elasticity) "," high transparency "Energy", "dive deep (bass rich)", "resonance" "self-excited" "harmonic" "harsh" "irritability" "fog" "fuzzy" "hair floating" "Powerless" "tail" and so on are to describe the speaker is not a good subjective evaluation of words.

Trick 1: voice, the song of the midrange part should be open

If the different styles of the singer's song sounds a little bit of nasal, a little boring or dry hard, you can certainly say that the speaker response to the frequency band some problems.

Trick 2: the bass should be no distortion

The investigation of the midrange is dominated by the human voice, and the vocals are within the frequency range of 150Hz-2500Hz, including the speech and singing, mainly to distinguish the color of the medium which is most likely to have the medium frequency. Sound instability, tone is not coherent, the human voice with a clear low weight "nasal" phenomenon, the sound dry, empty, nausea, - these can be seen as obvious defects in the speaker. Even the smallest bookshelf speakers will still be in the low frequency of some output, if you hear the bass guitar sound is not clear, some ring or rumble, and even a certain scale or a group of sound, it shows the speaker pairs 60 to 150Hz this frequency response is not good, if the vigorous male voice sounds a little "cavity sound" or some contrived, the same description of the poor response in this band.

Trick three: treble section of the problem

Although a lot of music does not appear a lot of treble (referring to 10 ~ 20kHz this paragraph), but jazz and rock music in the obvious treble, so you can use good recording jazz CD to test to listen. In such CD records, most of the time will always appear again and again the clear transition period. Audition, to beats by dre wireless cheap beats seriously listen to whether the boring or "friends" who often say that kind of ambiguous.

In the low treble part of the main use of playing music, orchestra and symphony sound source for listening, demanding natural soft voice, rhythm, clear, This range of speakers and the sound source of the higher requirements, speakers can meet the above requirements we think that better, no longer harsh requirements. In the ultrahigh range we use clear jazz and some sound, such as broken sound, split sound, tweet and other characteristics of the source, mainly to observe the speaker treble transient expression. In the repeated transient treble to see whether the speaker sounds beats earphones crisp, clean, whether harsh, with or without burr, split sound, rustling and other obvious distortion.
