Night DJ sound control prompt

Lead: The hearing of ears is the life of DJ's work. Next, I will tell you something that DJ should pay attention to in the sound control at night.

1. Don't drink while the DJ is performing.

"If I see a DJ taking two or three shots in a scene, I'm sure he will eventually die. It's only a matter of time. " ——Johannes (If I see a DJ having two or three drinks during a performance, I'm sure it's only a matter of time before he finally becomes deaf).

I know it's a bit disappointing, but in fact, when the music is too loud, alcohol will hinder your perception. Simply put, when you are drunk, you will unconsciously do destructive things.

This concept is scientifically called "cocktail deafness", and there are quite a few clinical reports to support this statement. When you are drunk, you will lose your hearing, which means that you will keep pushing up the volume track. One of the research reports (the limitation of acute alcohol on hearing) points out that the alcohol concentration in the breath is directly proportional to the' hearing frequency' in hearing. Alcohol will weaken the sensitivity of human body to low frequencies, mainly at 1000 Hz, which is the most important frequency. In short, alcohol seems to affect your sensitivity to low frequencies.

2. Reduce the monitoring volume of the mixer.

For a DJ, most of the hearing loss is not the deafening music from the outfield speakers, but the noise that you have been in direct contact with for a long time. By adjusting the monitoring volume of the mixer, the influence of noise on the DJ can be effectively reduced, which will also help the ear recovery later.

If you feel it is necessary to protect your hearing, you can use a decibel detector, which can help you figure out what a safe DJ workbench is in a noisy environment. (The price of decibel detector Taobao is probably between 150-300! )

Scientifically speaking: keep your monitoring equipment below the safety critical value, and the concept can be known from the table of CDC by seeing the tolerable volume intensity in a short time.

3. Use external decibel measuring instruments.

Once exposed to noise for a period of time, the brain will have a stage where it is difficult to judge the volume. As time goes on, the situation will continue to deteriorate. Therefore, it is almost impossible to keep a certain volume all the time without an objective measuring tool.

"I suggest that Rich run his monitoring system at the following levels when mixing: outdoor speakers 100DB club speakers 103 Db bass G 106 db. If the reflection is really poor, then after completing equalization or mixing, I suggest that the monitoring system be turned down to 90 db for regular listening." -Johannes (I suggest the monitoring volume during mixing: 100Db is suitable for outdoor music venues. 103Db is suitable for nightclubs with low indoor ceilings. 106Db is suitable for spaces with very poor reflection. Then, reduce the volume of the EQ or audio track at a time. It is suggested to reduce the monitoring to 90Db and listen carefully again. )

Many DJs prefer to check the decibel level with their smartphones, and some App applications on the market can do it. However, it should be reminded that the microphone on the mobile phone device does not perform well when tested below the noise detection or above 100 dB, so the smart phone is not a precise measurement tool.
