“…In conclusion, no effect was noted on auditory system under or after exposure, and even after repeated cumulative RF exposure. Confirming results of the previous studies, several investigations (Paglialonga et al, 2007;Parazzini et al, 2007b;Stefanics et al, 2007) indicated there were no effects of GSM exposure on auditory functions.…”

The widespread use of wireless telecommunications devices, particularly mobile phones and wireless networks, has resulted in increased human exposure to radiofrequency (RF) fields. Although national and international agencies have established safety guidelines for exposure to RF fields, concerns remain about the potential for adverse health outcomes to occur in relation to RF field exposure. The extensive literature on RF fields and health was reviewed by a number of authorities, including the Royal Society of Canada (1999). This report is the third in a series of updates to the original report of the Royal Society of Canada, covering the period 2004-2007. In particular, the present study examined new data on (1) dosimetry and exposure assessment, (2) biological effects of RF fields such as enzyme induction, and (3) toxicological effects, including genotoxicity and carcinogenicity. Epidemiological studies of the potential health effects of RF exposure, particularly from mobile phones, were determined, along with human and animal studies of neurological and behavioural effects. Within the last 4 yrs investigators concluded that there is no clear evidence of adverse health effects associated with RF fields, although continued research is recommended to address specific areas of concern, including exposure to RF fields among children using mobile phones. The results of the ongoing 13-country World Health Organization INTERPHONE study of mobile phones may provide important new information on the potential cancer risks associated with mobile phone use.

“…The same group [Stefanics et al, 2007] failed to replicate their preliminary findings [Kellényi et al, 1999] even in an improved experiment (larger sample size, double-blind). A pooled analysis of the data obtained from a multicenter project [Uloziene et al, 2005;Paglialonga et al, 2007;Parazzini et al, 2007a;Stefanics et al, 2007] revealed no effects of short-term exposure to GSM signals on TEOAE, DPOAE, and ABR in 169 healthy young adults [Parazzini et al, 2007a].…”

“…Previous studies measured TEOAE and/or DPOAE before and after short-term exposure to GSM handset signals but found no significant effects (Table 3), even when using more sophisticated data processing to increase sensitivity to detect small changes in hearing function [Parazzini et al, 2005;Paglialonga et al, 2007]. As for the vestibular part of the inner ear, short-term exposure to GSM signals did not induce nystagmus, which was measured with videooculography (VOG) Bamiou et al, 2008].…”

For the last two decades, a large number of studies have investigated the effects of mobile phone radiation on the human brain and cognition using behavioral or neurophysiological measurements. This review evaluated previous findings with respect to study design and data analysis. Provocation studies found no evidence of subjective symptoms attributed to mobile phone radiation, suggesting psychological reasons for inducing such symptoms in hypersensitive people. Behavioral studies previously reported improved cognitive performance under exposure, but it was likely to have occurred by chance due to multiple comparisons. Recent behavioral studies and replication studies with more conservative statistics found no significant effects compared with original studies. Neurophysiological studies found no significant effects on cochlear and brainstem auditory processing, but only inconsistent results on spontaneous and evoked brain electrical activity. The inconsistent findings suggest possible false positives due to multiple comparisons and thus replication is needed. Other approaches such as brain hemodynamic response measurements are promising but the findings are few and not yet conclusive. Rigorous study design and data analysis considering multiple comparisons and effect size are required to reduce controversy in this important field of research.

“…To maximize accuracy of timeefrequency analysis of TEOAEs, we extracted the frequency components by using an algorithm based on the Wavelet Transform (WT) (Mallat, 1989), which is particularly suitable for the analysis of TEOAEs (Tognola et al, 1998). Algorithms based on the WT have been extensively used for timeefrequency analysis of TEOAEs to study, for example, the cochlear functionality in newborns (Moleti et al, 2005;Tognola et al, 2001), in preterm neonates (Moleti et al, 2008;Tognola et al, 2005), in adults with noise-induced hearing loss (Jedrzejczak et al, 2005;Tognola et al, 1999) or tinnitus (Paglialonga et al, 2010), or to monitor possible subtle cochlear modifications in subjects exposed to electromagnetic fields from mobile phones (Paglialonga et al, 2007). So far, no study has used timeefrequency analysis of TEOAEs to investigate the functionality of cochlear active mechanisms in subjects affected by WS.…”
