【短片】耳朵幾歲了 聽力檢測告訴你
Aug 14th 2013, 19:12

【綜合報導】基本上每個人都能聽到8000赫茲的音頻,50歲以下的可以聽到12000赫茲,40歲以下的可以聽到15000赫茲,30歲以下的可以聽到16000赫茲,24歲以下的可以聽到18000赫茲,20歲以下的可以聽到19000赫茲,但要注意這個影片由於經過壓縮,流失了19000赫茲的聲音。
 
如果以上所有頻率都聽得到,那你的年紀應該是在20歲以下,內耳不像肝臟或皮膚,沒有辦法再生,內耳內有數千個負責接收聲音的毛細胞,隨著年紀增長接受越多噪音,這些毛細胞就會被破壞,高頻的聲音會最先出現在音波上,因此受到更多壓力,也就會更快退化,所以年紀越大就越聽不到高頻的聲音。

聽力要顧好一但受損恐難恢復。翻攝AsapSCIENCE
