Tech-savvy students have adapted the Mosquito alarm into “The Teen Buzz” so they can receive calls and texts during class and the teachers don’t have the faintest idea what is happening. The sound is at an ultra-high frequency that can be heard usually only by people who are younger than 20. The recorded sound, which has been referred to as the Teen Buzz, is shared from phone to phone via text messages or downloads from the internet. With the Teen Buzz, the students can receive calls and texts during class without the teachers knowing it.
The sound frequencies used in the Teen Buzz usually in the 17 kHz (or 17000 cycles per second) range. This is generally above what adults can hear. To see how these higher frequencies sound, check out this demonstration. If you are older than 20, have someone younger than you listen with you. See how well you do.
As we age, we lose the ability to hear those ultra-high frequencies. The loss of hearing in those very high frequencies do not usually affect us. However a loss of hearing in some of the lower frequencies in the sound spectrum can affect our hearing of and understanding of speech.
Someone with a hearing loss in the frequencies affecting speech will often have one or more of the following complaints:
– “I can hear, but I have trouble understanding.”
– “If you would talk clearer, I would hear just fine.”
– “People talk too fast any more.”
– “My grand kids are hard to understand.”
– “I hear okay when everything is quiet. I have trouble hearing when there are background noises.”
– “I can hear you when you look at me. I can’t hear you when you are walking away from me.”
The experience of not hearing easily can be frustrating and embarrassing.
The good news is that there are solutions to those problems. The first step toward the solution is to call for an appointment to check your hearing.
