1, voice: wide bandwidth, small distortion, good linear, large dynamic range, and the distribution is evener, medium and low frequency band energy is outstanding, sound reverberation ratio appropriate, on listening feel full range is broad, comfortable.

2. Narrow voice: high and low bass, not wide band, low reverberation, and excessive middle frequency. If the multi-frequency tone compensator is raised too much in 800 Hertz, the sound is narrow, the pitch lacks the hierarchy, and the bass fullness is poor.

3. The sound is bright: in the evaluation of sound quality, sometimes it is called brightness or brightness. The whole range of bass, middle, and high pitch energy is abundant, and there is abundant homophonic and high frequency ceiling harmonic decay process is slow. At the same time, the proportion of reverberation is appropriate, the distortion is small, the transient response is good. Give a person a kind, active feeling.

4, voice: this is a reflection of the lack of high frequency and high frequency, especially in the more than 5000 ~ 6000 hz have obvious attenuation, studio or poor listening room acoustics conditions, medium and high frequency reverberation time is short, will sound on the auditory feel dull without luster.

5, voice thick: voice thick strong, low frequency, high don't lack, there is a certain brightness, low frequency and low frequency energy is stronger, especially in 200 ~ 500 hz voice out, suitable reverberation, low-frequency reverberation is not short, small distortion, playback sound tone scale peak amplitude modulation is not necessarily very high, but the loudness is relatively large, if picture requirements in the combination of film and television, the microphone properly handled, can give a person a kind of close shot voice thick feeling, also known as thick thick.

6, thin voice: sound thin and weak, poor resonance, reverberation, less average less energy, sound energy in the lack of low frequency and low frequency, the frequency response under 300 ~ 500 hz decline too much, will have the feeling of thin, sometimes called a single.

7, voice: wide frequency band, quality pure, little distortion, there is a certain strength and brightness, the bass is not muddy, tenor is not hard, barren, transient response is good, sound reverberation and the proportion of direct sound, reverberation characteristics, time is more appropriate, on the auditory feel plump, bright, clear and high fidelity.

8, sound flat, round, flat, is a kind of evaluation term commonly used by the department of music, refers to the narrow band, sound, sound quality is not pure, distortion larger or poor sound reverberation insufficiency, the fullness of meaning, such as multi microphone, multichannel recording including the studio sound field between phase is very important. The phase is wrong, the tone is flat and narrow, the bass lacks, the distortion is large, the fullness is poor. Sometimes it's called a flat.

9. Soft voice: there are two kinds of concepts, one is poor evaluation, the lack of middle or high pitch, the lack of dominant voice, the lack of intensity, and the other is good evaluation. Such as some electrical workers called south waxy or soft, it refers to the distortion is small, good damping, low frequency response spectrum broadening, between relaxation, low frequency, low and medium mount, reverberation sound right amount, on the auditory feel soft and comfortable.

In 10, sound hard: bass, treble, and upper limit of high frequency harmonics decay process is fast, low frequency sound reverberation is short, there is a clear intermodulation distortion, transient response is bad, damping is poor, with a little in the process of electroacoustic system or playback overload phenomenon or recorded shows high amplitude modulation will have hard feeling.

11 there are water, sound: distortion is small, wide frequency response and evenly, voice out, have certain loudness and brightness, sound reverberation and the proportion of direct sound right, especially in the high frequency reverberation is right amount, on hearing was not stem, fruity with water.

12. Sound dry: it is mainly a recording studio or audio-audible stereo condition difference, the diffusion is not good, the reverberation time is short, especially the lack of medium and high frequency reverberation sound, it sounds dry and difficult. In order to improve the sound quality, some irregular arc diffusers are often added in the recording studio to increase the reflection sound, or the artificial reverberator is used.

13, sound through: distortion is small, good transient response, wide frequency response and evenly, high mount, reverberation sound appropriate, especially in high frequency mixing enough, the bass is not paste, there is a certain strength, sound clear and bright, administrative levels feels good, sound good.

14, sound paste: vague and tone color paste into a, refers to the bass is overmuch, low-frequency reverberation time is too long, lack of high frequency, intermodulation distortion, or feel like a layer of veil, sound on the auditory feel brightness and clarity is poor, level is not clear.

15 and voice: strong, in the low frequency sound energy on average well level is bigger, in the high frequency and high frequency is not short, direct sound proportion is stronger, reverberation sound right amount, voice thick, high bright, small distortion, loudness.

16, sound empty: reverberation is too big, direct sound ratio is too small, no microphone direction on the sound source, the microphone is too far away from the sound source, or in place of reverberation is bigger with omnidirectional microphone accept the sound source, will feel empty, clarity is poor, the tonic is not outstanding, might even think of sound source location is not clear.

17, sound oscillation: the term also has two concepts, one is a good evaluation, Alt is not short, the bass is rich and pleasant, low frequency response spectrum broadening, and have enough energy, elastic, voice relaxation reverberation especially low-frequency reverberation slightly bigger, small distortion, such as with multiple tones compensator in 80 ~ 80 hz frequency of 4 ~ 6 db to listen to music can clearly feel the bass plump tone swings. Second, poor evaluation, if the bass too exaggerated, make the sound out of balance, or the lack of low-frequency sound source itself, and caused by the low frequency resonance peak of the loudspeaker box resonance, or poor damping, transient response is bad, will generate an additional bass, on auditory feel dull, lack of brightness and level, this is a kind of distortion, is high fidelity sound quality.

18. Sound wood: low or medium tones, poor sound diffusion, short reverberation, sound inactivity, stiffness, high frequency and low frequency.

19, voice soft, low frequency and low frequency energy fully, voice thick, loose, not tight, loudness, suitable reverberation sound bigger, small distortion, good transient loudness, a modest amount, high frequency within the main frequency and frequency response is uniform, and there is a certain brightness, it sounds easy, timbre plump and soft.

20. Voice tip: uneven frequency distribution, low bass, high and middle height, especially high volume, distortion, and auditory sensation.

21. Thick sound: low frequency sound density, relatively small medium and high frequency, strong sound color, strong intensity, and poor clarity and reverberation.

22. Fine sound: the sound energy density is small, the loudness is not enough, the voice is thin and weak, lacking of the frequency, the high frequency and high frequency, the sound is not enough, if some of the sound sources themselves sound fine, lack of resonance.

23, play sound: sound density, bass, tenor enough, there are certain loudness, small distortion, dynamic, wide frequency response, such as multiple microphone distance processing of artificial reverberation as long as with proper focus was solid, sound to send, and elastic.

24. Sound contraction: the sound density is small, the voice can not be delivered, the middle frequency is missing, the reverberation is low, the loudness is low and the distortion is large. Such as some poor theater, reverberation short, diffusion is bad, actors speak loudly, the sound or not, always feel that the sound source far inside, clear and master degree of difference, tone is not abundant.

25. The sound is clear: the frequency is wide and even, especially in the middle and high frequencies, the sound is bright and the reverberation is appropriate.

26, sound turbidity: intermediate frequency and low frequency in reverberation is too big or too much energy, small proportion of direct sound, melody is not prominent, lack of high frequency, brightness difference, harmonic distortion and intermodulation distortion, transient response is bad, will give a person a kind of voice turbidity, clarity is poor level of feeling. 27, sound be afraid: too much in the high frequency and high frequency, and the distortion is larger, and a momentary overload phenomenon, damping, square wave with parasitic oscillation, on auditory feel high frequency sound, the sound when the coarse is not clean.

28, voice: passband distortion is larger, there are additional higher harmonic, and associated with distortion of transient phenomena, overload distortion in electroacoustic device, audio equipment, such as vacuum tube amplifier of the coupling capacitor leakage, transistor amplifier the static current is too low, the speaker voice coil some scattered or touch the ring, actor throat is bad, can have hoarse.

29. Sound blasting: the sound energy density is large, the high frequency and high frequency are too much, excessive distortion in the recording or amplifying system is serious, and there is a phenomenon of overload peeling.

30. Voice breaking: the sound energy density is too large, with serious harmonics and intermodulation distortion. From microphone able to withstand the maximum sound level of the sound source to the mixer, the recorder of linear reserves the power allowance to the amplifier, speakers, any level have overload cut the top distortion, would have broken the sense of the party, serious still can with lindsey are to the noise, the recording tape high remanence, optical severe am also can produce the tape broken sound quality.

31. Sound boredom: the lack of high-pitched and medium-high notes has severe attenuation at 3000~4000 hz, low frequency reverberation, low frequency energy, especially around 150 hz. Low frequency linear distortion, transient response is not good. The reason for the boredom is that the sound source itself is stuffy, the high frequency of the electroacoustic system is falling, the pickup is improper, the magnetic head is attached to the gap, the magnetic powder is blocked, and the tape and magnetic head are not fit. Sometimes the sound condition of the recording studio is poor, or it is affected by the air temperature, which makes the high frequency absorption strong, the reverberation is short, the medium high frequency diffuses the difference, also can cause the feeling of the sound stuffy.

32. Sound coaxed: low middle frequency is an exaggeration, resonant, uneven frequency, reverberation too long. For example, if the reverberation is not used properly, there will be a kind of coaxing bathroom effect, and it will also produce a coaxing feeling with multi-frequency tuning at 300 Hertz, which will affect the clarity.

33. Sound hum: the nasal sound is heavy, especially if the speaker has a cold stuffy nose, and resonates in the 100-250hz band. For example, if you raise too much in 150Hz, you will feel a significant increase in nasal voice, and the sound will be hum, which will seriously affect the clarity.

34. Sound dispersion: the sound is not strong, the focus is empty, the main melody is not prominent, the reverberation is too large, the middle frequency is deficient, the frequency is not even. The recording studio is empty, the microphone is too far away, the whole band is poor, and the sound is messy and scattered.

35, sound wave: general is microphone directivity did not cause any voice does not focus on the sound source, or is too far away from the sound source, direct sound enough, indirect voice too much, lack of alto, sound energy and sound level smaller on average, low volume, clarity is poor. In the recording sound system, because of the unstable speed, the position of the tape will swing and cause the level to shake, and there will be a floating sensation in the hearing.

36. Sound shaking: during recording or replaying, the sound is shifted by mechanical transmission, resulting in a change in the volume of the continuous rule, and the sound is shaking in the hearing. If a very low frequency of the cycle wobbles, the sound can be heard shaking unevenly, shaking and affecting evenness.

37. The sound has a vibrato: this is mainly the acoustic defect in architectural acoustics. Such as sound source in two parallel surface, or arc domes, easy to cause the vibration echo, sound felt continuous overlay, voice trembling phenomenon, even seriously interfere with the clarity of sound.

38, sound jump: not coherent, general music is singing, dialogue, or feel mutation on the volume, such as the volume is not balanced, the grid frequency instability, and make the tone is not unified, before and after the background noise not cohesion, voice cut off end, actors mood incoherent, magnetic tape and magnetic head poor contact, etc., will be on the auditory feel jumping, not natural. Especially like a film shot of a single lens composition, therefore, should pay attention to the coherence of the sound.

39. Sound crisp: uneven frequency, low frequency, high frequency and high frequency, high distortion, thin sound, not thick, increased in 7000~8000Hz, and there is a sense of brittleness.

40, too many teeth sound or tooth distortion: the dental sound is also known as S sound, which is a reflection of the high subharmonic transient distortion in the process of sound. Mandarin pronunciation of the energy in high frequency band is nearly 10 db higher than English, Hungarian, plus a consonant wide spectrum, lung rushed out of the air, and easily make the microphone diaphragm produce irregular movement, thus, in the process of recording, if put to the microphone sound too close, and no wind hood, and it is easy to cause excessive or distortion of dental disease, there is burr on the auditory sense or distortion of hush.

41. Lead bark (or heavy metal sound) : the medium high frequency has a prominent or resonant peak, the frequency is uneven, the distortion is large, the underdamping, the transient response is not good. For example, a moving coil microphone or high pitch speaker with poor quality often feels hard and is accompanied by a sound of lead, which is called metallic sound in the north.

42, melting, wide frequency response, distortion and signal-to-noise ratio, such as large dynamic range, under the condition of the song and the band uniform multiple parts in volume, tone, sound reverberator options, including: characteristics, time, proportion is appropriate, the entire audio blend together, and shows the band integral feeling is very good, rather than on the auditory feel sound is discrete.

Clean: between sound, between instruments, between languages, low noise, little interference, no additional components. The small distortion, high fidelity, good transient response, reverberation sound fit, especially low frequency reverberation but large, studio, listening room noise level is low, sound condition is good, sound playback system noise ratio is high.

44. Group sense: refers to a song, band or some of the sounds in order and with a good thickness, a good level, a strong sense of integrity, and a suitable dynamic range. For example, the arrangement of the microphone is reasonable, considering the coverage of the performer, and appropriately utilizing the delay and reverberation, which can help to enhance the group sense of sound.

45. Stereo sense: the sound is not only hierarchical, but also spatial and spatial. For stereo, it should reflect the different positions of the sound source in space. The sound image orientation is clear, the width is good, the recording sound channel must be loud, the distortion is small, the reverberation is appropriate, the dynamic range is large.

46, environmental sense: this is the pick up process using the simulation technique of a commonly used term, more emphasis on in the film and television, sound environment, characters to match the picture or proportion of Musical Instruments in the picture, far or near, have a close-up, close shot, middle, vision, panoramic, a hall, valleys, indoor and outdoor, outdoor, etc. Voice have the sense of environment, the depth of feeling, distance feeling, this is the direct sound and sound reverberation, the length of the reverberation time, and the proportion of the volume, pitch, the layout of microphone, try to achieve the consistency of the auditory and visual make sound conforms to the specific environment atmosphere.

47, kindness: this is a requirement of higher comprehensive evaluation, it requires the loudness appropriate, high resolution, good nature, reverberation sound right amount, broad range, low distortion, low noise level, make the person feels is in sound condition good concert hall, theater, studio directly to listen to the band, people face to face talk, feel kind nature.

48, fullness, thick, fruity voice, sound power is larger, have certain loudness, the high frequency is not short, brightness is good, especially in the low frequency and low frequency energy is sufficient, voice send that channel distortion is small, good transient response, reverb sound enough. Sometimes it's called warmth.

49, balance: generally speaking balance has two meanings, one is the indoor natural balance, namely the balance between the voice and the song, group with a balance of, because of it and specific room environment, the construction characteristics closely inseparable, so the indoor natural balance contains two aspects the meaning of art and technology, the other is to pick up technical balance, if the indoor natural balance is good, and cause imbalance of recording finished product, this is technology link did not reflect well. On the other hand, the lack of indoor natural balance, but in the process of the pickup handled well, use technical means to make up for the deficiency of natural balance, balance and harmony, the work up and this is our pickup technique on a very important work.

50. Noise level: this is one of the important indicators of high fidelity sound quality. Low noise level can improve the definition of music or language, and expand the dynamic norm of sound.
