Tws headset is a pronunciation system, the advantages and disadvantages of a tws headset is not an external factor can be determined, the use of certain materials and a structure does not represent anything, good tws headsets design is modern electro-acoustic materials science, ergonomics And sound aesthetics of the perfect combination.
Evaluation of tws headset technical parameters:
① Distortion
Harmonic distortion, tws headset output signal waveform and the input signal is not the same, has changed, this change is the distortion. This change will produce new harmonics, the greater the change the greater the new harmonic, so the use of total harmonic distortion to represent the less harmonic produced less distortion. Therefore, the less the harmonic distortion, the higher the fidelity of the tws headset. Harmonic distortion will cause the main voice of the hard, fried; and steady-state or transient intermodulation distortion mainly caused by sound rough, sharp hard and turbid. Both make the sound quality degradation, if the distortion of more than 3%, the sound quality deterioration significantly.
Phase distortion, mainly caused by 1kHz below the low-frequency sound blur, while affecting the sound level and sound frequency positioning.
② frequency response and transient response
Frequency response refers to the gain or sensitivity of the audio equipment with the signal frequency changes, with the passband width and in-band non-uniformity (such as high-quality power amplifier frequency response 1Hz ~ 200kHz ± ldB). The wider the bandwidth, the better the high and low frequency response: the smaller the non-uniformity, the better the frequency balance performance. 300Hz ~ 500Hz in the low-frequency sound pressure is too much to strengthen, the sound turbidity, excessive attenuation, the voice fatigue; 500Hz ~ 5kHz in the high-frequency (500Hz ~ 5kHz), low-frequency low-frequency sound to a certain degree of foundation, So that the sound has a certain brightness, over-enhancement, the sound stiff; excessive attenuation, the sound scattered, floating; 5kHz ~ 10kHz high-frequency sound to a certain level, color; excessive strengthening, sound spikes; , Hair nausea. According to this law, according to a variety of hearing sense, quantitative adjustment of the sound system frequency response.
Transient response refers to the ability of the acoustic system to follow a sudden signal. In essence, it reflects the high-order harmonic distortion of the pulse signal size, serious impact on the quality of transparency and layering. Transient response Common conversion rate V / μs that the higher the index, the smaller the harmonic distortion. For example, the conversion rate of the general amplifier> 10V / μs.
③ signal to noise ratio
The signal to noise ratio, which represents the difference between the signal and the noise level, is expressed in terms of S / N or SNR (dB). The frequency of the noise, the signal strength of the human ear is not the same. Usually, the human ear to 4 ~ 8kHz noise most sensitive, weak signal than the strong signal by the noise impact is more prominent.
④ channel separation and balance
Channel separation, refers to the degree of isolation between the different channels of stereo, with a channel signal level and string into another channel signal level difference to represent. The greater the difference the better.
Channel balance, refers to the two-channel gain, frequency response characteristics such as consistency. Otherwise, it will cause the channel sound image deviation.
Consumers in the evaluation of tws headset sound quality but also rely on to listen to a sense of good tws headsets sound sense of hearing has the following characteristics:
1. Sound at the end of pure, without any unpleasant "hiss", "Om", "coax" sound.
2. A sense of balance is good, sound never too bright or too dark, high-frequency low-frequency energy distribution, the integration between the natural smooth, no abrupt and burr.
3. High-frequency extension of a good, delicate and supple.
4. Low frequency dive deep, clean and full, flexible and intensity, without any fat, slow feeling.
5. IF distortion is very small, transparent and warm, warm voice of nature, a thickness, magnetic, not exaggerated dental and nasal.
6. Resolution is good, rich in detail, a small signal can also be a clear replay.
7. A good sound field characterization, sound field open, accurate and stable instrument positioning, sound field, there is sufficient information, there is no empty feeling.
8 dynamic no obvious compression, has a good sense of speed, large volume distortion or distortion is not very small. Such a tws headset can be more perfect playback of any type of music, a good degree of truth and music, long-term use will not cause fatigue, can make the listener immersed in music.
Listening is also a subjective, different people listen to feel there are differences. The sound quality of a tws headset with different people according to their own preferences will be very different evaluation. Young people prefer the world's best music bass heavy headphones will be more popular among young people, the elderly prefer soft music clear voice tws headsets more popular with the elderly.
