Our hearing has a secret bodyguard: a newly discovered connection from the cochlea to the brain that warns of intense incoming noise that causes tissue damage and hearing loss, according to new research by Northwestern Medicine scientists.

Scientists believe they have identified the ear’s own novel pain system that protects it from very loud or damaging noise. It may be the reason you jam your fingers in your ears when a fire engine or ambulance wails close by. The nerves that normally alert you to pain – like touching a hot burner on a stove – are not present in your inner ear. So, it needs its own private alert system.

The discovery may provide insight into the cause and treatment for such painful hearing conditions as hyperacusis, an oversensitivity and earache in response to everyday sounds, common in soldiers exposed to explosives in the military, and tinnitus, a persistent and uncomfortable ringing in the ears.

NAD Files Lawsuit to Make “Family-Friendly” Resort Accessible  Friday 7/01/2011

The National Association of the Deaf (NAD), Vargas & Stein, LLP and Chason, Rosner, Leary & Marshall filed a lawsuit against Great Wolf Resorts, Inc. in the United States District Court for the Eastern District of Virginia. Great Wolf Resorts, Inc, a national chain of indoor water parks, offers different forms of entertainment including a popular attraction, “MagiQuest”, which is described on its website as a “live-action adventure game in which a player goes up to a station and waves an electronic wand in order to trigger an auditory-based clue to locate the next station.”

When Plaintiff K.M., a deaf child, visited a Great Wolf Lodge in Williamsburg, Virginia, she was not able to participate in the interactive game with her hearing siblings. Similarly, co-Plaintiff Suzanne Rosen Singleton, a deaf mother, was barred from providing support to her hearing children in figuring out the clues. Great Wolf Lodge also features storytelling puppet shows that rely heavily on audio.
