Abstract:

In this work the theoretical assumptions are given for an acoustic siren of higher performance.

This siren emits a wave which comes close to the form of a rectangular wave.

It represents the results of research on the siren. From the assumptions can be constructed in addition an analysis of the emitted acoustic energy and the so-named expansion coefficient.

Zusammenfassung

In der Arbeit werden theoretische Voraussetzungen einer akustischen Sirene hoher Leistung beschrieben. Diese Sirene emittiert eine Welle, die nach ihrer Form der rechteckigen Welle recht nahe kommt.

Es wurden die Untersuchungsergebnisse der Sirene dargestellt. Die Sirene wurde nach diesen Voraussetzungen unter besonderer Berucksichtigung der Analyse der emittierten Energie und des sogenannten Ausdehnungskoeffizienten konstruiert.

Sommaire

On énonce les hypothèses théoriques à partir desquelles on peut établir le projet d'une sirène acoustique à haut rendement. Une telle sirène doit émettre une onde dont la forme se rapprochera beaucoup de celle d'une onde rectangulaire.

Puis on expose les résultats obtenus dans l'étude de cette sirène. La sirène a été effectivement construite à partir des hypothèses énoncées, mais en tenant compte aussi de l'analyse de l'énergie émise et des facteurs de propagation.
