Abstract
Mobile phones are the necessity in modern life. The exposure to electromagnetic field emitted by mobile telephones is increasing rapidly that causes side effects, which may be thermal and non-thermal side effects. Thirty non-user participants and sixty user participants (who use mobile phones for more than 1 hour for more than 2 years) were included in the study. Users participants were further sub-divided into Group A (which use mobile phones for more than 1 hours for more than 2 years but less than 5 years) and Group B (who use mobile phones for more than 1 hours for more than 5 years). Auditory status of the subjects was assessed by Brainstem Evoked Response Audiometry (BERA). Latencies of waves I, III, V and inter-peak latency of I-V were recorded in users and non-users. There was a significant change in the latencies of BERA potentials of wave I and III in users compared to non-users. These changes suggest that radiations emitted from mobile phone causes damage to inner ear, cochlea and may be outer hair cells of inner ear. These results show that electromagnetic frequencies of mobile phone cause some damage to ear and auditory pathway. The study shows that mobile phones have a detrimental effect on the human auditory system.
Highlights
Mobile phones have become a necessity in human day to day life
Sensations of burning or warmth around the ear [2], headache [3], disturbance of sleep [4], alteration of cognitive functions and neural activity [5,6], as well as alteration in the blood-brain barrier and a change in the regional cerebral blood flow have been reported as effects resulting from mobile phone usage [7,8]
Brain stem evoked response audiometry or Brainstem Evoked Response Audiometry (BERA) is an important non-invasive technique to access the functioning of auditory pathway
Summary
Mobile phones have become a necessity in human day to day life. Mobile phones are used to make and receive calls, which in turn receive and emit electromagnetic radiation [1]. These electromagnetic radiations are absorbed by the body. These radiations are proven to be harmful to different organ systems of human body. Ill effects of electromagnetic radiations on humans are rightly assumed as the matter of serious public health concern. Any detrimental biological effect(s) related to mobile phone use should be considered as a high-priority health issue and a potential matter of scientific discussion
