|Exposure duration||continuous for 30 min|
|Distance between exposed object and exposure source||4 cm|
|Setup||The handset was oriented in the normal position for use over the right ear and the microphone oriented towards the corner of the mouth. The antenna was located about 4 cm from the head.|
|Additional info||For all subjects, three experiments were performed that were separated by at least 1 week. The order of three measurements was counterbalanced among the subjects.|
None of the 3 measures were affected by exposure to pulsed electromagnetic field emitted by a mobile phone for 30 min. The authors conclude that 30 min mobile phone use has no short-term adverse effects on the human auditory system.
