Multimedia speaker manufacturers teach you how to judge a speaker from the speaker tone?

How to evaluate a sound is good or bad? Multimedia speaker manufacturers think this question is worth discussing. Multimedia speaker manufacturers tell you mainly through two aspects to evaluate. One is the subjective evaluation, that is, relying on the human ear hearing organs to feel the sound to the person's feelings; two is the objective evaluation, that is, the real quality of the sound. Subjective evaluation rely on listening, objective evaluation rely on testing, or test standards to measure.

　　Multimedia speaker manufacturers tell you if the subjective evaluation to evaluate the sound is good or bad, there are some imperfections. There are many factors that affect the subjective evaluation.

　　1. Sensitivity of the human ear

　　Multimedia speaker manufacturers tell you due to the differences in each person's physiological structure, health, development, each person's hearing sensitivity is different, and the hearing sensitivity of the left and right ears is also different.

　　2.The influence of age on hearing

　　Multimedia speaker manufacturers tell you that due to physiological reasons, with the growth of age, the eardrum, cochlea and other auditory organs of the different frequency receptors of the organisation of the elasticity of the weakening, and therefore the ability to discriminate between high-frequency sound will gradually decline, thus affecting the accuracy of the sound quality evaluation.

　　3. Influence of education level.

　　A person's level of education affects the subjective evaluation. Multimedia speaker manufacturers tell you because the field of acoustics is a multidisciplinary complex physical phenomena, with physics, mathematics, architecture, music and other disciplines have close links.

　　4. Art appreciation.

　　Each person's artistic cultivation and concepts are different, resulting in different understanding of the artistic expression of tone. This is also one of the factors affecting the evaluation of timbre.

　　5. Human psychological influence.

　　Each person in different periods, different moods, different living environments, different psychological state (state of mind), the feeling of the tone is not the same. This also affects the subjective evaluation of timbre.

　　6. Each person's preference

　　Multimedia speaker manufacturers tell you that everyone in different areas of art may belong to this or that school of art, so everyone has a certain psychological preference, which is allowed. So this factor also affects the evaluation of sound quality.

　　7. Different countries and nationalities

　　Different countries, different nationalities, different regions, different times, have different standards and listening habits for the understanding of timbre. So the evaluation of timbre varies a lot. So the subjective evaluation is a kind of feeling of comprehensive art evaluation, affected by a variety of factors.

　　Multimedia speaker manufacturers tell you to make subjective and objective evaluation of sound quality, you need to know and understand the structure of the timbre, especially the overtone structure, and have the ability to analyse.
