A new study suggests that long-term use of a cell phone may damage a person's inner ear and high frequency hearing ability.
Presenting the study at the American Academy of Otolaryngology-Head and Neck Surgery Foundation's Annual Meeting & OTO EXPO in Washington, DC, the researchers said that 100 people who had used cellular phones for over a year suffered increases in the degree of hearing loss over the span of 12 months.
The researchers have also found that people who used their phones for more than 60 minutes a day had a worse hearing threshold than their counterparts with lesser use.
Symptoms such as ear warmth, ear fullness, and ringing in the ears (tinnitus) are the early warning signs of an auditory abnormality, say authors of the study.
The authors also said that the use of earphones was safer than holding a mobile phone up to the ears.
