Does it also mean that using synthetic speech may harm as well?

People using mobile phones for more than four years and longer than 30
minutes a day are at risk of developing hearing loss particularly at higher
speech
frequencies, a study conducted by Post Graduate Institute of Medical
Education and Research at Chandigarh has said.

"This hearing loss was more in the dominant ear (ear of use). Presence of
fullness in the ears, ear warmth, strange noises in the ear are warning
signals
which should not be ignored," Dr Naresh Panda, head of the department of
Otolaryngology at PGIMER, who along with his team conducted the 18-month
long
study, said.

He said the aim of the study, which is a preliminary one, done on 100 long
term mobile phone users from Chandigarh, was to assess if long term mobile
phone
use had any adverse effect on hearing and central auditory pathways.

Panda said the study was conducted on people between the age group of 18-45
years and those who were using GSM handsets.

The study group was divided into three categories -- those using mobile
phones for 1-2 years, 2-3 years and 3-4 years and above.

Asked if PGIMER was suggesting that people should stop using mobile phones,
Panda said it was just a preliminary study and our aim is not to spread
panic
among the public. All we are saying that people should limit or curtail
their usage and take measures like using ear phones.
