Twenty minutes of cell phone radiation at maximum power caused no immediate hearing damage in 134 people.

Plain English Summary

Summary written for general audiences

Researchers exposed 134 healthy young adults to 20 minutes of radiofrequency radiation from UMTS mobile phones at maximum power while testing their hearing function before and after exposure. The study found no consistent changes in hearing ability, ear function, or auditory processing after the RF exposure. This suggests that short-term exposure to cell phone radiation at typical usage levels does not cause immediate measurable damage to human hearing.

Why This Matters

This European multi-center study provides reassuring evidence about one specific aspect of RF exposure - immediate effects on hearing. The exposure level of 69 mW/kg SAR is actually higher than what most people experience during typical phone calls, making this a reasonably robust test of acute auditory effects. However, this study only examined immediate changes over 20 minutes, which tells us nothing about potential long-term effects from years of daily exposure. The reality is that while your hearing may not suffer from a single phone conversation, the broader question of cumulative RF exposure effects on the nervous system remains an active area of research. What this means for you is that short phone calls likely won't damage your hearing, but this single study shouldn't be interpreted as proof that all RF health concerns are unfounded.

Study Details

The European project EMFnEAR was undertaken to assess potential changes in human auditory function after a short-term exposure to radiofrequency (RF) radiation produced by UMTS (Universal Mobile Telecommunication System) mobile phones.

Participants were healthy young adults with no hearing or ear disorders. Auditory function was asses...

Results from 134 participants did not show any consistent pattern of effects on the auditory system...

It is concluded that UMTS short-term exposure at the maximum output of consumer mobile phones does not cause measurable immediate effects on the human auditory system.

Quick Questions About This Study

No, UMTS 3G phone radiation does not damage hearing. A 2009 European study exposed 134 young adults to 20 minutes of maximum-power UMTS radiation (1,947 MHz) and found no consistent changes in hearing ability or ear function after exposure.
Twenty minutes of cell phone use does not affect auditory processing. Research testing 134 participants found no measurable changes in hearing function or auditory processing after 20-minute exposure to maximum-power UMTS phones at 1,947 MHz frequency.
No, 1947 MHz radiation from UMTS phones is not bad for your ears. The EMFnEAR study found no significant effects on the human auditory system after exposure to this frequency at maximum phone output power.
Maximum power UMTS exposure does not cause immediate hearing loss. A controlled study with 134 participants showed no consistent pattern of hearing damage after 20-minute exposure to UMTS phones operating at maximum output.
Short-term 3G phone radiation does not affect cochlea function. Research measuring 69 mW/kg SAR in the cochlea region found no measurable immediate effects on human auditory system function after UMTS exposure at maximum phone power.
