中文摘要 | 本科於1996年3月間,針對國中一、二年級學生(男105名、女94名),利用ヾ問 卷調查; ゝ音聲檢查含最長呼氣時間( maximum breathing time, MBT )、最長發聲時間 ( maximum phonation time, MPT )及說話基頻( speaking fundamental frequency ) ;ゞ肺活量( vital capacity )檢查及々耳鼻喉局部檢查等,觀察及分析其變聲前後之發 聲狀態、聲帶外觀及其自覺症狀, 並獲得如下之結果:ヾ國一男生 78.2 %( 25/32 )、 國二男生 94.5 %( 68/73 )已進入變聲期;ゝ 58.5 %( 55/94 )男生知悉其變聲之年 齡;而女生知悉其變聲之年齡者只有 5 名,與男生有明顯差異。90 %已變聲之男生,其年 齡主要介於 11 到 14 歲間,平均為 12 歲 8 個月; ゞ變聲期出現之各種明顯自覺症狀, 以高音發不出者居首;々變聲前,男生平均說話基頻為 250 Hz,變聲後為 130 Hz;ぁ音聲 檢查之結果:男生平均最長發聲時間為 21.7 秒, 其中異常者(小於 14 秒) 6 名( 5.7 %);女生為 19.0 秒,無異常者。平均最長呼氣時間( MBT )男生為 36 秒,女生為 31 秒,變聲前後並無多大差異; あ肺活量檢查:男生肺活量( VC )平均為 3375mL,女生平 均為 2808mL。呼氣流率近似值( phonation quotient=VC/MPT )男生平均為 155mL/sec, 女生平均為 148mL/sec,變聲前後並無多大差異; ぃ喉局部檢查所見:聲帶充血泛紅者 22 名(男 17 名、女 5 名),有泡沫現象者( bubbling effect ) 2 名(無女生); 此外 ,並無聲帶異常者。 |
英文摘要 | We studied the voice mutation in juvenile group in Taipei city. The sample group consisted of 105 boys and 94 girls who were students of the first and second grades in a junior high school. In this report questionnaire, phonation, vital capacity and local findings of the ears, nose and throat were studied. The results are as follows: 78.2% of the first grade boys and 94.5% of the second grade boys reached the mutation. 58.5% of boys were aware of their voice mutation, while only 5.3% of girls noticed that. More then 90% of boys presented voice mutation at the ages between 11 and 14, with mean age of 12 years and 8 months. Being unable to make high pitch voice is the most common symtom of boys during mutational stage. The average speaking fundamental frequencies of boys are 250 Hz in premutation stage and 130 Hz in post-mutation stage. Six (5.7%) boys had abnormal maximum phonation time (<14 second). |
