Furthermore, the study also discovered that people who used their phones for more than 60 minutes a day had a worse hearing threshold than those with less use.High frequency hearing loss is characterized by the loss of ability to hear consonants such as s, f, t, and z, even though vowels can be heard normally. Consequently, people hear sounds but cannot make out what is being said.The authors warn users of cell phones to look out for ear symptoms such as ear warmth, ear fullness, and ringing in the ears (tinnitus) as early warning signs that you may have an auditory abnormality. They also suggest the use of earphones, which they found to be safer than holding a mobile phone up to the ears.Taken from www.newswise.com/articles/view/533259/Diane Hofstetter
