Technischer HintergrundTechnical background

Ein Helm dient hauptsächlich zum Schutz des menschlichen Kopfes. Allerdings sind die Funktionen eines traditionellen Helms sehr einfach und können modernen Anforderungen meist nicht genügen. So ist z. B. eine interaktive Kommunikation oder das Abspielen verschiedener Medien während der Fahrt nicht möglich. Manche der heutigen Helme erfüllen nur die Basisfunktion des Sicherheitsschutzes und bieten keine Möglichkeit zur Sprachkommunikation, was verdeckte Sicherheitsgefahren mit sich bringt. In einigen bekannten Helmen werden herkömmliche luftleitende Lautsprecher und luftleitende Mikrophone eingesetzt, so dass eine Sprachkommunikation in einer lauten Umgebung nicht möglich ist. Auch ist es dem Anwender in der Regel nicht angenehm, einen herkömmlichen Lautsprecher lange Zeit am Ohr zu tragen. Außerdem wird dadurch die Wahrnehmung von Umgebungsgeräuschen beeinträchtigt, so dass die Verkehrssicherheit gefährdet sein kann.A helmet is mainly used to protect the human head.
