Hoe komt ECHO voor?

De spiegels zullen de beelden stromen en het licht terug sturen. De muren sturen ook de stemmen terug. Als u zich een beetje verder weg van een hoge muur of een grote klif, hoort u uw stem spinnen terug een paar seconden later.

Als een geluidsgolf tegenkomt een muur of een hoge en brede rots oppervlak, het draait achteruit naar de bron. Dat is hoe de echo gebeurt. Als het geëxtraheerde geluid kort is en de geluidsgolven de batterij als normaal bereiken, wordt de echo duidelijk gehoord. Sporen van het geluid blijven in het oor voor 1/10 seconden.

Omdat de snelheid van het geluid in de lucht 340 meter per seconde is, moet de afstand tussen de audiobron en de batterij een ECHO zijn ten minste 17 meter.
