In this world full of noise and interference, I want to be quiet
In this world full of noises and disturbances, when we say "I want to be quiet", others will never really calm you down, just put self-humor on your face: calm, who is that?
If you feel like you are immune to noise early on, it's too naive - we are called "resilience" to the noise, but it's nothing but hearing, and the ears can't hear too much detail.
If you don't believe it, you can try clicking the audio below, with 30% of the volume scrolling to see if you can hear the sound:
This is a high frequency sound wave called a "mosquito".
If you are under the age of 25 but cannot hear these sound waves, it means that your ears have entered early aging -
All kinds of noise contact with the bad habits of the ear are caused by the aging of the stimulus. There is now a solution to this problem, and the invention of the interferer makes it easy for you to solve the problem. So how do I buy this type of high performance cell phone jammer?
1. Make sure you know the frequency of the network. Africa, Europe, the Middle East, and Asia use most of the 900 MHz and 1800 MHz bands.
2. Make sure you understand your local communication service provider. In Germany the network standard is UTMS, 4G, CDMA and GSM. Before purchasing a cell phone jammer, you should contact the internet which can give you complete information on the frequency of your area.
3. Determine the area of interference and the purpose of the application. For a small part, like a classroom, it is small and portable enough. But if you want to use it in a 10,000 seat theater, you will need to purchase a large capacity telephone handset with a large area of interference.
With a jammer you have a quiet living environment, then hurry to choose a signal jammer that is right for you
