Silence may lead to phantom noises misinterpreted as tinnitus

Phantom noises, that mimic ringing in the ears associated with tinnitus, can be experienced by people with normal hearing in quiet situations, according to new research published in the January 2008 edition of Otolaryngology - Head and Neck Surgery.

The Brazilian study, which consisted of 66 people with normal hearing and no tinnitus, found that among subjects placed in a quiet environment where they were asked to focus on their hearing senses, 68 percent experienced phantom ringing noises similar to that of tinnitus. This is compared to only 45.5 percent of participants who heard phantom ringing when asked to focus on visual stimuli and not on their hearing, and 19.7 percent of those asked to focus on a task in a quiet environment.

"What if I told you," Joel Weinstock said, "there were countries where the doctors had never seen hay fever?"

Have a Heart; Here's How

A few exercises to help increase your feelings of empathy:

Building empathy for your intimate partner

Envision a characteristic or behavior of yours that you know your partner dislikes. Imagine shifting your consciousness into your partner's perspective, even though you may disagree with that perspective.

Immerse yourself in your partner's perceptions of you. Try to experience them fully. At the same time, hold on to your own views.

Then try to understand your partner's attitudes as a reflection of who he or she is, based on all the influences and choices that have shaped him or her. Don't judge.
