閾値とは、ある音を聞き取ることができる最小の音の大きさ（デシベル）のことです。つまり、その音が聞こえるか聞こえないかの境界線となる音の大きさです。閾値が低いほど、小さな音でも聞き取ることができることを意味します。 A threshold is the minimum sound level (in decibels) at which a person can detect a sound. In other words, it's the boundary between hearing and not hearing a sound. A lower threshold means better hearing ability, as the person can detect quieter sounds.

1.横の線は音のピッチを示し、低い音から高い音までを表しています。縦の線は音の大きさを示し、静かな音から大きな音までを示しています。
2.グラフ上の記号は、異なる音のピッチで聞こえる一番小さな音を表します。
3.記号が上部（０）に近い場合、聴力は良好です。下にある場合、聴力があまり良くないかもしれません。
4.記号が-10 dBから25dBの範囲にある場合、健聴と言われています。それ以下の場合、聴力が低下している可能性があります。(*)
自分の閾値を理解し、必要なら適切な診断を得るためには耳鼻咽喉科医のような専門家を受診しましょう。

1. Look at the graph with two lines. The horizontal line shows the pitch of sounds, from low to high. The vertical line shows how loud the sounds are, from soft to loud.
2. The symbols on the graph represent the softest sounds you can hear for different pitches.
3. If the symbols are near the top, your hearing is good. If they're lower, your hearing might not be as good.
4. If the symbols are in the -10 dB to 25 dB range, your hearing is normal. If they're below that, you might have some hearing loss.
Remember, it's best to talk to a hearing expert, like an audiologist, to fully understand your threshold and get the right help if needed. (*)WHO Ear Health
