Listening diagnosis audio system operating symptoms

The sound is broken (劈): severe harmonics and intermodulation cause distortion, and there is a “beep” sound, and the flat top has been cut, and the distortion is greater than 10%.
The sound is hard: there is harmonic distortion, and the distortion is between 3% and 5%.

Sound explosion: too high frequency or medium and high frequency, there are harmonics and intermodulation distortion.

Sound sand: medium and high frequency distortion, transient distortion.

The sound is dry: there is distortion, slightly higher in the medium and high frequency, and there is transient distortion.

The sound is boring: the high frequency or medium and high frequency is too small, or the directivity is too sharp and deviates from the axis.

The sound is stunned: the transient is not good, the resonance peak of the speaker is prominent, and the low frequency or medium and low frequency is excessive.

The sound is thick: the frequency bandwidth, the medium frequency, the low frequency is good, and the reverberation is moderate.

Slim sound: high frequency and medium and high frequency moderate, small distortion, good transient, no transient intermodulation distortion.

Levels: good transients, flat frequency characteristics, moderate reverberation.

Solid sound: good mid-low frequency, moderate reverberation, and loudness.

The sound is divergent: the intermediate frequency is lacking, the intermediate frequency transient is not good, and the reverberation is too much.

Narrow sound: narrow frequency characteristics.

Metal lead sound: The medium and high frequency individual points are prominent and the distortion is serious.

The sound is rounded: the frequency characteristics and distortion indicators are good, the reverberation is moderate, and the transient is good.

There is moisture: medium and high frequency and high frequency are good, and reverberation is enough.

The sound is bright: medium and high frequency and high frequency are sufficient, the frequency response is flat, and the reverberation is moderate.

Sound spike: too much high frequency and medium and high frequency.

Sound virtual (floating): lack of intermediate frequency, medium and high frequency and high frequency directivity is too sharp.

Sound dry: lack of reverberation and medium and high frequency.

Balance or concord: good frequency characteristics and low distortion.

Booming: The resonance peak of the speaker is severely prominent, the distortion is large, and the transient is not good.

Transparency: high frequency and medium and high frequency moderate, small distortion, good transient.

Good definition: medium and high frequency and high frequency, good distortion, good transient and moderate reverberation.

Strong body feeling: flat frequency response, moderate reverberation, low distortion and good transients.

The sense of presence or presence: the frequency response is good, the characteristics are good in medium and high frequency, the distortion is small, and the stereo effect is good.

Plump: Frequency bandwidth, good mid-low frequency, moderate reverberation.

Soft: low frequency and medium and low frequency, the distortion is small.

Have a good voice, good strength: loud enough, good reverberation, low frequency and low frequency.
