The exposed and the control group run though the standard audiometry analysis plays different audiometric responses up only to higher frequencies ( 2000 HZ p = 0 . 009 and 4000 Hz p = 0 . 04 ) ; in high - frequency audiometry , as all other frequencies , the attention is drew to the fact that the sample groups distinguish themselves in a significantly statistic way ( 10 , 000 Hz p = 0 . 025 , 12 , 000 Hz p = 0 . 008 , 14 , 000 Hz p = 0 . 026 , 16 , 000 Hz p = 0 . 08 ) .
