From the people who are engaged in audio, there is a kind of professional habit that is subtle in the bones. When I came across a system, I listened for a while, and when I was fresh, I started to pick up the problem. I felt that there was a problem with this voice. There was a problem and the effect was not satisfactory.
In fact, I think that the sound effect can be divided into personal effects, commercial effects and professional effects.
Personal effects refer to the effects that you like, similar to those played by enthusiasts. This effect is only for a few people. It is good for your taste. If you don't meet your taste, you will feel bad, with a strong personality. Sign.
The commercial effect is to provide a musical atmosphere to the audience of the audio, such as what kind of bar. The people who face this effect are not paying attention to the details of music, but enjoying the atmosphere created by music. This kind of effect strives to give people a comfortable sense of hearing, and it is not easy to cause people's hearing fatigue. It is a strategy to cooperate with commercial marketing. This kind of effect often does not require a sense of overall balance, and does not require a sharp feeling. The pursuit of maximum is the comfort of the subjective sense of the masses, rather than the objective and accurate expression.
Professional effects (only from the type of effect, not to the sound pressure level) are prepared for professionals (that is, related practitioners), pursuing the accurate expression of objective details and the subjective overall balance, such as recording monitors. Or stage monitoring. This effect is a tool for the staff and performers to complete their work, not to let the staff enjoy the music atmosphere. This effect is a tool attribute, and the pursuit is accurate and comprehensive.
For personal needs, if you use the recording monitor, many people feel bad, no taste, it is rubbish.
In commercial and entertainment occasions, if you pursue professional effects, people tend to feel irritating in a short period of time, but listening for a long time is easy to feel tired and unable to stand.
For professionals, if you adjust the system according to the commercial effect, people will often feel that the sound is wrong, the expression is incomplete, and the direction cannot be found.
In fact, no matter what effect, no one is good, who is not good, the key is to see where it is used. In other words, picking the wrong disease should also choose the right place, huh, huh~~ Just like judging the car audio and the performance sound, if you look at the details, the car audio can't be compared.
For example, an audio is the main business effect, its style is not accepted by many audio professionals, but its voice is recognized by many non-professionals. It is not that it is not professional enough, but that it professionally serves the mass market. It is not a professional, but a special one.
Similarly, martin audio's black line series products are aimed at the expression of electronic dance music, and the performing arts performance is second; and as one of the leading products of the performance products, MEYERSOUND is familiar, but the phenomenon is to use Kanebo's monitor box to go to KTV. It is estimated that few guests are willing to sing. If you take the card box of KTV to monitor the sound engineer, the sound engineer must have to cry, which side is north? Hehe~~~.
Oil immersed transformer thermometers include oil level thermometers and winding thermometers, including WZT series, BWY series and BWR type. Dry Type Transformer thermometers check the transformer temperature by inserting the sensor probe into the low-voltage winding side through a digital display; It can work normally under extreme severe weather conditions, and the maximum measuring temperature can reach 500 ℃.
The pressure thermometer is a thermometer for temperature measurement based on the change relationship between the saturated vapor pressure and temperature of the vaporized liquid in the closed temperature measurement system.
The principle of the pressure thermometer is based on the change relationship between the saturated vapor pressure and temperature of the vaporized liquid in the closed temperature measurement system. When the temperature bulb senses the temperature change, the saturated steam in the closed system will generate corresponding pressure, causing the curvature change of the elastic element, causing the displacement at the free end. Then the gear amplification mechanism will change the displacement to the indicated value. This thermometer has the characteristics of small temperature bulb, fast response, high sensitivity, and intuitive reading. It almost combines all the advantages of glass rod thermometer, bimetallic thermometer, and gas pressure thermometer, It can be made into shockproof and anti-corrosion type, and can realize remote contact signal, thermal resistance signal, 0-10mA or 4-20mA signal. It is the most widely used and comprehensive mechanical temperature measuring instrument.
For oil level thermometer, when the temperature package experiences temperature changes, the saturated steam in the closed system will generate corresponding pressure, causing the curvature of the elastic element to change and the free end to shift, and then the gear amplification mechanism will change the displacement to the indicated value. The thermometer has the characteristics of small temperature package, fast reaction speed, high sensitivity and intuitive reading. It almost collects all the advantages of glass rod thermometer, bimetallic thermometer and air pressure thermometer, and can produce anti-seismic and anti-corrosion type, realizing remote contact signal, thermal resistance signal, 0-10mA or 4-20mA signal.
The temperature indicating controller is mainly composed of elastic element (bellows), capillary tube and temperature package. The sealing system composed of these three parts is filled with temperature sensing liquid. When the measured temperature changes, the volume of temperature sensing liquid in the temperature package will also change. This volume increment is transmitted through the capillary to the elastic element (bellows) in the instrument, resulting in a corresponding offset. The offset can be amplified by the mechanism to indicate the measured temperature, drive the micro switch, and output the signal to drive the refrigeration system to control the temperature rise of the transformer.
