OTRC: Justin Bieber lawsuit: Mom suing for $9.2 million over hearing damage

Justin Bieber talks to OnTheRedCarpet.com at the 2012 Billboard Awards on May 20, 2012.

An Oregon woman has sued teen pop star Justin Bieber for $9.2 million, saying she suffered permanent hearing damage from one of his concerts two years ago.

The 18-year-old heartthrob, who is often following by screaming fans, has not responded to the lawsuit. Stacey Wilson Betts, 47, says that she and her daughter attended a show he put on at the Rose Quarter in Portland on July 14, 2010.

She is representing herself in her lawsuit, which was filed on Wednesday and posted on OnTheRedCarpet.com. Betts says that at one point during the performance, the singer climbed into "a heart-shaped, aluminum/steel gondola and was pulled out over the crowd."

She states that "Bieber created a wave-like effect of screaming by pointing into various sections of the arena, then enticed the crowd into a frenzy of screams by continuously waving his arms in a quick and upward motion."

"The gondola that Justin Bieber was suspended in acted as a sound conductor, creating a sound blast that permanently damaged both of my ears," she says, adding that Bieber and co-defendants Island Def Jam Records, promoter AEG Worldwide and venue owner, Vulcan Sports Entertainment displayed "negligence" by allegedly failing to "maintain safe decibels at all times during their events."

The parties have also not comments about the matter. Betts said a "respected audiologist" carried out multiple hearing tests on her and that she was told that she had hearing loss, tinnitus and hyperacusis and that her injuries were permanent.

Tinnitus is marked by a sound of buzzing, whistling or ringing in the ears. Those who suffer from hyperacusis have more sensitivity to sounds.

People who attend concerts sometimes experience such ailments, whose effects can last for hours, days or longer, depending on how close they sat to speakers and what the condition of their hearing was like beforehand. Many diehard concertgoers wear earplugs.

Betts did not specify where she sat at the concert. She also did not explain why she filed her two years after the concert. She also did not say whether or not her daughter suffered injuries.

Betts says her "quality of life" has been "permanently reduced in addition to the injury." She is suing for $9.2 million for "expenses, pain and suffering, loss of quality of life, severe tinnitus, hyperacusis and permanent disability and impairment" to both of her ears."
