年齢別の聴力リファレンス
このテストについて
このテストは8kHzから20kHzまでの高周波を聞く力を測定します。加齢とともに、内耳の有毛細胞の損傷により高い周波数は自然に聞こえなくなっていきます。
ほとんどの大人は15〜17kHzまで、子どもや10代は20kHzまで聞こえることが多いです。大音量の音楽や騒音は聴力低下を加速させます。
大事な注意
- • 機材が影響: 良いヘッドホンかスピーカーを
- • 音量: 快適なレベルで、大きすぎず
- • 環境: 静かな部屋でテストを
- • 医療ではない: 娯楽・教育目的のみ
- • 難聴の心配: 気になる場合は専門医へ
なぜ高域を失うのか
- • 加齢: 有毛細胞の自然な劣化
- • 騒音曝露: ライブ、ヘッドホン、機械
- • 遺伝: 生まれつき聴力が良い人もいる
- • 健康: 特定の疾患が聴力に影響
聴力を守る
- • 音量を下げる: 60/60ルール(音量60%、最長60分)
- • 耳栓を使う: ライブや大音量イベントで
- • 休憩を取る: 定期的に耳を休ませる
- • 定期チェック: 専門的な聴力検査を受ける
