Listening Evaluation Terms

The sound is broken (splitting): severe harmonics and intermodulation cause distortion, there is a "pop" sound, the flat top has been cut, and the degree of distortion is greater than 10%.

The sound is hard: there is harmonic distortion, the degree of distortion is between 3% and 5%

Explosion of sound: too much high-frequency or middle-high frequency, there are harmonics and intermodulation distortion.

The sound is sandy: medium and high frequency distortion, with transient distortion.

The sound is dry: there is distortion, a little more in the middle and high frequencies, and there is transient distortion.

The sound is boring: there are too few high-frequency or mid-high frequencies, or the directivity is too sharp to deviate from the axis.

The sound is muddy: the transient is not good, the speaker resonance peak is prominent, and there are too many low or medium and low frequencies.

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

Slim sound: Moderate high-frequency and mid-high frequency, low distortion, good transient, no transient intermodulation distortion.

There are layers: good transient, flat frequency characteristics, and moderate reverberation.

The sound is solid: the mid-low frequency is good, the reverb is moderate, and the loudness is sufficient.

Sound divergence: lack of intermediate frequency, poor intermediate frequency transient, excessive reverberation.

Narrow sound: narrow frequency characteristics.

Metal lead sound: individual points in the middle and high frequencies are prominent, and the distortion is serious.

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

Moisture: The mid-high frequency and high frequency are good, and the reverberation is sufficient.

Bright sound: mid-high frequency and high frequency are sufficient, the frequency response is flat, and the reverberation is moderate.

Spiked voice: too much high frequency and mid-high frequency.

Virtual sound (floating): Lack of mid-frequency, mid-high frequency and high-frequency directivity are too sharp.

Sound dry: lack of reverberation and mid-to-high frequencies.

Balance or concord: good frequency characteristics and low distortion.

Roar: The resonance peak of the speaker is seriously prominent, the distortion is large, and the transient is not good

Transparency: Moderate high-frequency and mid-high frequency, low distortion and good transient.

Good clarity: good mid-to-high frequency and high frequency, low distortion, good transient, and moderate reverberation.

Powerful somatosensory: flat frequency response, moderate reverberation, low distortion and good transient.

Presence or presence: the frequency response is good for transients, the characteristics are good in the middle and high frequencies, the distortion is small, and the stereo effect is good.

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

Soft: Appropriate amount of low-frequency and mid-low frequency, low distortion.

Courage and good strength: sufficient loudness, good reverberation, good low and mid-low frequencies.
