| [the estimation of hearing threshold for high frequencies in children from the upper silesia]. | study was carried out in frequency range 8-18 khz with audiometer as 10 hf. lack of internationally accepted reference value of the hearing threshold of air conduction at extended frequency range resulted in own evaluation of the audiometric zero point for air conduction at the range 8-18 khz in "otologically healthy" subjects younger than 20 years. they were divided into subgroup a and b according to age. investigation of the threshold values for air conduction at extended range of high frequen ... | 2002 | 12162025 |
