Hearing Loss from Mobile Phone Use

H atrial auricleing Loss from Mobile Phone Use paroleMobile crys have become a part of modern intent style. There has been rapid boom in the number of expeditious call ins in the recent decade. This rapid worldwide expansion of restless telephones raises questions regarding possible effectuate of the emitted radiofrequencies on the health of the consumers. The electromagnetic waves contribute affect the homosexual health ranging from increase the blood pressure, ca make use of memory red ink and induce migraines, auditory modality impairment to even cancer can also occur. Of all the anatomical reference structures, the ear is in the closest proximity to the wandering(a) phones, hence most potential organ system to be damaged by the electromagnetic waves emitted from the officious phones.Pure tone audiology is a key earshot test for assessment of hearing threshold of the individual. It de borderines the degree of hearing firing and also type and configuration of hearing loss. Pure tone audiology uses both air and bone conduction audiometry, the type of loss can be identified by the air-bone gap.In our read, while comparing the results of keen tone audiometry in understands (n=60) and total cases (n=60), it was order that in control group 51 individuals had normal hearing threshold, 08 had mild hearing loss and 01 had moderate hearing loss. Of the total cases, 39 had normal hearing threshold, 19 had mild hearing loss and 2 had moderate hearing loss. No individual in the cases or control group had severe or profound hearing loss. qi squargon test with yates correction was use for statistical analysis of the data, and difference was found to be significant (p value0.05). era comparing the results of distorted product otoacoustic waiver (DPOAE) in controls (n=60) and cases Group A (n=30), it was found that in cases group A, 19 individuals passed the test and 11 individuals failed the DPOAE test. Chi square test was applied for statistical analysis of the data, and results were not found to be significant (p value0.05).On comparing the results of distorted product otoacoustic emission (DPOAE) in controls (n=60) and cases Group B (n=30), it was found that in cases group B, 15 individuals passed the test and 15 individuals failed the DPOAE test. Chi square test was applied for statistical analysis of the data, and results were not found to be significant (p value0.05).The European experience emfnEAR, was through to assess the harmful effectuate of short term electromagnetic waves emitted from UTMS busy device over the satellite hair cells. Functioning of out hair cells was assessed by DPOAE. They concluded that short term ikon to EMFs of mobile phones does not cause measurable immediate make on the human auditory system.Renzo R et al also conducted a similar study to assess the short term effects of mobile phone use on ear, assessed by transeunt evoked otoacoustic emissions and brainstem evoked audiometry response. T he study parameters were similar to our study but they studied the short term effects of EMFs in contrast to our study where we tried to find the effects of long term exposure. They did not find any change in the auditory functions, in front and after the short exposure to electromagnetic radiations.Ozturan et al assessed transient evoked OAE and distorted product OAE in adults exposed to 10 min telephone call using GSM mobile phones. The tests were through with(p) before and after the exposure. They concluded that otoacoustic emissions did not change after the electromagnetic waves exposure.Bamiou DE et al also reported that there was no change in the transient evoked otoacoustic emission, due to electromagnetic waves of mobile phones.S Bhagat et al, studied the effects of inveterate exposure to EMF emitted from mobile phone on home(a) ear by using distorted product otoacoustic emissions. Individuals using mobile phones for more than 4 years were studied. It was concluded that l ong-term and frequent exposure to EMFs from mobile phone does not cause damage to outer hair cells of cochlea.P. Karthikeyan et al did a study on hundred students who were mobile phone users. They were divided into two groups of more than and less than two hours of mobile usage. DPAOE was done and compared to controls. Significant change in DPOAE was seen in cases, more so in group with more than two hours of cell phone usage.Alsanosi AA et al did a study to assess the immediate consequences of 60 minutes exposure to mobile phones on hearing function by determining changes in whirl product otoacoustic emission (DPOAE) and hearing threshold levels (HTLs). They concluded that sixty minutes of close exposure to electromagnetic works emitted by a mobile phone had an immediate effect on HTL assessed by beautiful-tone audiogram and inner ear (assessed by DPOAE) in young human subjects.While in our study, on comparing DPOAE, we did not find any significant difference in the midst of t he total cases and controls. On comparing the each sub group of cases to controls, no statistically significant difference was noted. This is in concurrence with most of the studies done in India and abroad. Though, P. Karthikeyan and Alsanosi have shown different results from those spy in our study.Though a lot of research publications are available in favour of and against the results observed in our study, but in all these studies studied the effects of electromagnetic frequencies of mobile phones on functioning of outer hair cells, but no criteria was taken as standard for comparison as different while (in years) of exposure, different hours per day of use, and acute effect v/s chronic effects. The major limitation of epidemiological studies addressing the health effects of mobile phone use is related to exposure assessment. Also, other factors were not taken in account like exposure to noise, which is known to cause damage to outer hair cells much before any change in pure to ne audiometry is seen (Anjali Desai et al, 1999) (RJ Salvi ea at, 2000). So, with all these factors nothing can be give tongue to with much certainty. Further research is needed to establish the effect of EMF on outer hair cells.The present scientific evidences are meagre to support the belief that there w ailing be no ill effects on human health and the present safety standards are enough to protect users from ill effects, if any. This present situation of scientific precariousness calls for the requirement of both precautionary measures and further research. Ill effects of mobile phone use on health might be of the field of interest for future research.We conclude from our study that mobile telephones should be apply for short periods only, only for essential purposes, and unnecessary long conversation over mobile phones should be avoided.
