Wie wirkt Echo?

Die Spiegel fließen die Bilder und senden das Licht zurück. Auch die Wände schicken die Stimmen zurück. Wenn Sie etwas weiter weg von einer hohen Wand oder einer großen Klippe stehen, werden Sie Ihre Stimme ein paar Sekunden später wieder drehen hören.

Trifft eine Schallwelle auf eine Wand oder eine hohe und breite Felsfläche, dreht sie sich rückwärts zu ihrer Quelle. So passiert das Echo. Wenn der extrahierte Ton kurz ist und die Schallwellen die Batterie wie gewohnt erreichen, ist das Echo deutlich zu hören. Die Spuren des Klangs bleiben im Ohr für eine Sekunde.

Weil die Geschwindigkeit des Klangs in der Luft 340 Meter pro Sekunde beträgt, muss der Abstand zwischen der Audioquelle und dem Akku, um ein Echo zu sein, mindestens 17 Meter betragen.
