Positive and negative sound quality evaluation term

A wide sound - narrow sound

The wide sound indicates the frequency bandwidth, small distortion, good linearity, large dynamic range and uniform distribution, suitable reverberation, rich and comfortable listening, and wide sound range.

The narrow sound indicates that the frequency band is narrow, the high and low frequencies are lacking, the intermediate frequency is excessively prominent, and the reverberation is small.

B The sound is bright - the sound is dark.

The sound is bright, also known as brightness or brightness. It is low in the whole audio range, moderate in midrange, high in treble, rich in homophonic and slow harmonic decay. At the same time, the reverberation is suitable, the distortion is small, and the transient response is good. The listening sound is bright, clear, active and intimate.

Dark sound refers to the lack of high frequency and medium frequency, especially in 5-6Hz, there is obvious attenuation, medium and high frequency reverberation is insufficient, and the sense of hearing is dim and glory.

C Sound is thick – the sound is thin (single).

Thick sound means thick and powerful sound, full bass, high-pitched sound, low-frequency, medium-frequency energy, especially in the 100-500Hz frequency, and the reverberation is appropriate, the distortion is small, and the listening sound is thick and powerful.

The sound thinness means that the sound is thin, lacking strength, poor resonance, insufficient reverberation, especially lack of near-reflex sound within 50ms, and there are not many harmonics, and the average intensity of sound energy is weak.

D sound circle - sound flat

The sound circle means pure sound quality, minimal distortion, and a certain intensity and brightness. Frequency bandwidth, low bass, medium sound is not hard, high sound is not harsh, transient response is good, reverberation is appropriate, full of hearing, bright, clear, round, fidelity.

Sound flat means that the sound quality is impure, the sound is thin, the distortion is large, the frequency band is narrow, and the reverberation is insufficient.

E Sound through - sound paste (clear sound - turbid sound).

Sound transmission means good sound transparency, strong resolution, layered, clear and bright distortion, good transient response, uniform frequency bandwidth, full and high frequency reverberation, unambiguous bass, strong intensity, clear and pleasant listening. .

The sound paste means that the sound is ambiguous, turbid, has intermodulation distortion, too much bass, has a resonance peak, lacks middle and high notes, and the bass reverb is too large.

F sound is real - the sound is empty.

The sound actually means strong sound, high average sound level in the middle and low frequency, high frequency and medium and high frequency, lack of direct sound ratio, moderate reverberation, small distortion, thick and bright sound.

The sound is too long, the reverberation time is too long, the direct sound ratio is too small, the main sound is not prominent, the sharpness is poor, and the sound image is blurred.

G Sound is soft - the sound is sharp.

Soft sound means low frequency and medium and low frequency energy is sufficient, sound is thick and slack, moderate loudness, reverberation time is slightly longer, distortion is small, transient response is good, medium and high frequency, high frequency is appropriate, frequency response is uniform, soft sense of hearing, sense of hearing Comfortable and smooth.

The sound tip is uneven in frequency response, the treble is too strong and has a resonance peak, the distortion is large, and the sound is harsh.

H sounds moist (with moisture) - dry sound.

Sound lubrication means that the frequency response is wide and uniform, the distortion is small, there is a certain degree of loudness and brightness, the proportion of reverberation sound and direct sound is appropriate, and the listening feeling is comfortable and smooth.

Sound dry means that the sound is dry, not smooth, the frequency response is uneven, the reverberation time is short, and especially the mid-high frequency reverberation is lacking.

I sound soft - hard sound

Soft sound has a double meaning. The good side is that the sound distortion is small, the damping is good, the reverberation is appropriate, the low frequency, the middle and low frequency are better, the sound is slack, and the listening is soft and comfortable. The bad side is the lack of high-pitched sounds. The main tone is not prominent enough and there is no strength.

Hard sound refers to the lack of bass, the middle and high notes are too much, but the middle and high sounds decay too fast, the reverberation is insufficient, there is obvious intermodulation distortion, the transient response is not good, the damping is poor, and there is overload phenomenon.

J sound swing - sound wood

The sound swing also has a double meaning. The good thing is that the middle and high notes are not lacking, the bass is slightly more and nice, the distortion is small, the sound is slack and flexible, and the bass is full. The downside is that the bass is overly exaggerated and distorted. The low frequency reverberation is slightly larger, the sound is out of balance, and there is a lack of brightness and level.

Sound wood refers to middle and high notes, low treble, lack of homophonic sound, unclear timbre, large distortion, insufficient reverberation, and uncomfortable sound.

K sound is thick - fine sound

Thick sound means strong low frequency, high intensity, weak middle and high frequency, rough tone, poor clarity and reverberation.

Fine sound refers to insufficient loudness, slender sound, lack of low frequency, high frequency and high frequency, and insufficient reverberation.
