A new study suggests the more you talk on your cell phone, the less you may actually be able to hear.
According to research presented at the American Academy of
Otolaryngology-Head and Neck Surgery Foundation's Annual Meeting &
OTO EXPO in Washington, DC, 100 people who had used mobile phones for
over a year suffered increases in the degree of hearing loss over the
span of 12 months.
found that people who used cell phones frequently, at least once a
day, have a harder time hearing high frequency sounds, especially in
their right ear and the sound of consonants, in particular.
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.

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
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.
