Can you still hear 18kHz?

以前から気にはなってたんです。オーディオのはなし。

I have been wondering about that. It’s about audio in a different point of view.

受け取り手である人間の耳の特性が人それぞれバラバラなんやから、みんな同じ音に聞こえるわけないやん、って。

I mean, does all people listen to the very same sound, even though the listener’s audibility (in sound frequency) is different each other?

以前から携帯電話の呼出音として使うとどうよ? ってな感じで一部で話題になっていた Mosquito Ring Tone。幸い、私はまだ 18kHz も聞こえましたが、さすがに 2〜3回聞いただけで、耳鳴りがするというか、耳が疲れてしまいます。さて、皆さんはどこまで聞こえますか?

The famous Mosquito Ring Tone, which is inaudible for most adults, has been used among teenagers as a ring tone for mobile phones. Luckily I can still hear 18kHz sine wave (at least now), but after listening to it several times, my ears do complain that they are very tired and I feel bad… Anyway, can you still hear all high-frequency tones?
