Honestly before reading this news, I didn’t know that by the age of 20, people will lose hearing for the highest frequencies – 18 to 20kHz. Okay now that you know also (admit it, you didnt know it too right?) let’s get on with the news.
Kids (in America I assume) took advantage of this knowledge and took a sound in this frequency, named “Teen Buzz” and use them as their ringtones.
So now they can hear their cell ringing during class and leave the clueless teacher wondering what’s all the giggling is about. Originally, the sound was used by some shopping complexes security to drive away young teenage gangs from their buildings.
I guess they’ll lower the sound so that they won’t get irritated by the sound. Hmmm kids – so clever nowadays.
