| High Pitched Sounds Only Some Can Hear |
| 10/20/2009 |
| Cell phone rings are often loud and annoying, but there`s one cell phone ring that can only bother some people. That`s because only a select crowd can hear it. Most people over the age of 30 can`t hear certain high-pitched tones. That`s why some higher schoolers have turned to the ring to communicate to each other at school. They can hear it, but many of their teachers can`t. Audiologist Brady Ness says teenagers are able to hear the high pitch ringing sound, which is similar to the sound of a mosquito because their hearing is still intact. "Basically a lot of our younger generation haven`t damaged their high frequency hair cells enough that they can still here those, but those of us who have damaged them throughout our life we don`t even hear those tones anymore," says Ness. High frequency hearing is the first type of hearing a person loses. Ness says well of 90 percent of hearing loss cases he sees have to do with high frequency loss. |
