  Schalltrichter für reflektierte Schallwellen. 



   Die den Gegenstand der Erfindung bildende Vorrichtung dicnt dazu, um Musikern, Sängern und Rednern bei Übungen eine genaue Kontrolle der Tonstärke und Tonhöhe bzw. Aussprache dadurch zu gestatten, dass die vom Ursprungsort direkt ausgehenden Schallwellen nicht zum Ohr gelangen können, sondern das Ohr nur reflektierte Schallwellen aufnimmt. 



   Dies wird gemäss der Erfindung dadurch erreicht, dass an beiden Ohren möglichst dicht anschliessende, durch einen Stahlbügel verbundene Schalltrichter angebracht werden, die so (entweder nach   rückwärts   oder aufwärts) gerichtet sind, dass sie nur die von den Wänden reflektierten Schallwellen aufnehmen. 



   Dies kann entweder so durchgeführt werden, dass die   Schalltrichter   seitliche Öffnungen besitzen, in welche die Ohrmuschel   passt-hiebei können   die Trichter vollkommen geschlossen oder halb offen sein Es können aber auch die Trichter nicht direkt das Ohr   überdecken,   sondern an einem über das Ohr gestülpten, dosenförmigen Gehäuse, welches überdies noch durch eine   Filz-,   Samt-oder Tuchdichtung gegen aussen schalldicht abgedeckt ist, aufwärts oder   rückwärts   angeordnet sein, wobei in diesem Falle diese beiden dosenförmigen Gehäuse gleichfalls durch den das Anliegen am Kopfe bewirkenden Federbügel verbunden sind.

  Horn for reflected sound waves.



   The device forming the subject of the invention is designed to allow musicians, singers and speakers during exercises to precisely control the tone strength and pitch or pronunciation, so that the sound waves emanating directly from the place of origin cannot reach the ear, but only reflect them Picks up sound waves.



   According to the invention, this is achieved by attaching horns connected as closely as possible to both ears, connected by a steel bracket, which are directed (either backwards or upwards) so that they only pick up the sound waves reflected from the walls.



   This can either be done in such a way that the horns have lateral openings into which the auricle fits - the horns can be completely closed or half-open, but the horns can not cover the ear directly, but rather on one that is slipped over the ear Can-shaped housing, which is also covered from the outside soundproof by a felt, velvet or cloth seal, can be arranged upwards or backwards, in which case these two can-shaped housings are also connected by the spring clip causing them to rest against the head.
