Grating spotlight photographyThe light gathering function of the grating in photography was to only allow light rays smaller than a specific angle to pass through, and light rays larger than this angle were blocked, thereby changing the angle of illumination and the effective illumination area to achieve the light gathering effect. For example, the grill of the softbox was similar to the honeycomb board of the standard cover. The honeycomb board had different angles (such as 10 degrees, 20 degrees, 30 degrees, 40 degrees, etc.), and with the four-leaf board, it could achieve more precise light control. In terms of photography equipment, there were many products related to spotlight photography, such as 60*90cm quick-mounting rectangular spotlight soft light box grill quick-release flash photography light, which was suitable for live photography and video shooting scenes; There was also the Huguang spotlight, the grill model. It came with a precise beam angle (such as the industry's first 13° beam angle, taking into account 22° and 34° angles), which could help create a layered image. At the same time, it was developed and manufactured using a high-standard craftsmanship system. It had many advantages to meet the needs of photography.

Slow response of the reflection gratingThe slow response of the reflection grating could be caused by many factors. In the field of safety light barriers, if the accuracy was not high enough or the response time was too long, the response time was slow, and the delay was too slow, it would lead to a large error in the measurement. For example, in the field of industrial safety light curtains, the security 6-point or 8-point total height of about 1.2M was used. The circuit principle of this light curtain was simple, and there were problems of low safety factor and slow response speed. It could not be applied in this field, but its advantage was its low price. In addition, as the human body gradually deteriorated with age, the reflection of light would weaken, resulting in slow reflection of light. This was a normal physiological phenomenon, but this principle could also explain that the reflection grating might have a slow response due to its own structure.

noise meterA noise meter, also known as a sound level meter, noise detector, decibel meter, etc., was the most basic noise measurement instrument. It was an electronic instrument, but it was different from objective electronic instruments such as a voltage meter. When converting sound signals into electrical signals, it could simulate the time characteristics of the human ear's response speed to sound waves. It had the characteristics of different sensitivity and the intensity characteristics of different loudness. It was a subjective electronic instrument. It measures the sound level and frequency of environmental noise to assess the impact of noise on human health and the environment. Common noise meters such as the VC824 digital noise meter have a measurement range of 30 - 130dBA, 35 - 130 dCC, a storage environment humidity of 10 - 80%RH,and a use environment humidity of 10 - 70%RH.1

arbitrary noiseHe didn't quite understand the exact meaning of the expression 'random noise'. If you want to ask about the general knowledge of noise, from a physiological point of view, any sound that interfered with people's rest, study, and work, as well as the sounds that people wanted to hear, that is, unwanted sounds, are collectively referred to as noise. When noise causes adverse effects on people and the surrounding environment, it forms noise pollution. If you want to ask a specific question about noise, please be more specific.

Disgusted by the noiseIt was normal to be disgusted by noisy sounds because noise would cause people to be irritated and endanger their health. It was a type of unpleasant and annoying sound. If this kind of disgust is more serious, you can consider going to the psychology department for consultation.
From a health point of view, noise can bring a variety of harm, such as hearing damage, sleep disruption, cardiovascular disease, psychological effects, psychophysical effects, and even mental illnesses. Different frequencies of noise had different harms. For example, low-frequency noise could cause continuous harm to people. It resonated with the frequency of the noise through the low-frequency vibration close to the internal organs, which could cause irreversible damage to the heart, lungs, spleen, kidneys, liver, etc. Long-term exposure to low-frequency noise could easily cause emotional distress, nervous breakdown, insomnia, headache, irritability, and even loss of reason. It could also affect the fetus in the womb of pregnant women.
In terms of noise management, if it was indoor renovation activities, square tweeters, hawking and other noises, the public security organs would be the main management; if it involved air conditioning, restaurants and other social life noises, the urban management would be the main management; the noise generated by industrial enterprises would be the main management; the noise generated by roads and other traffic would be the main management. In addition, during legal rest days, holidays, working days from 12:00 to 14:00 and from 18:00 to 8:00 the next day, it was forbidden to carry out renovation construction that would cause noise in the community building that had been handed over for use. During other periods of time, the renovation should also try to reduce noise interference. If they are harmed by noise, individuals have the right to ask the other party to eliminate the harm, and those who cause losses can demand compensation according to law; If they violate the laws and regulations on the prevention and control of noise pollution in social life and create noise to interfere with the normal life of others, they will be given a warning first. If they do not correct after the warning, they will be fined between 200 yuan and 500 yuan.
