Description

Rundfunksender Bekanntlich werden bei Rundfunksendungen Sprache und :Musik mit praktisch dem gleichen Pegel gesendet. Das führt dazu, daß die Sprache gegenüber der Musik unnatürlich laut wiedergegeben wird. Die Sprachwiedergabe klingt demnach infolge ihrer ztt hohen Lautstärke zu tief und dadurch sehr unverständlich, was durch die bei den modernen Empfängern vorgesehene Baßanhebung verstärkt wird. Diesen Nachteil kann man dadurch beseitigen, daß man die für die lfusikwiedergabe vorgesehene 13aßanhebung bei Sprachwiedergabe abschaltet. Dies ist jedoch sehr umständlich.Broadcasters It is well known that radio broadcasts use language and : Music sent at practically the same level. That leads to the language is reproduced unnaturally loud compared to the music. The speech reproduction sounds therefore too low due to their high volume and therefore very incomprehensible, which is amplified by the bass boost provided by modern receivers. This disadvantage can be eliminated by using the for music playback The intended 13aßanigung switches off during speech reproduction. However, this is very cumbersome.

Eine solche Bedienung von kundfunkempfängern wird ülyerflüssig, wenn erfindungsgemäß bei der Sendung von Sprache, jedoch nicht von Musik, die tiefen Töne gegenüber den mittleren Tönen so weit abgesenkt oder die hohen Töne gegenüber den mittleren Tönen so weit angehoben werden, daß die Sprache beim Empfang, insbesondere mit den üblichen Rundfunkempfängern mit Baßanhebung, nicht dumpf klingt.Such an operation of radio receivers becomes unnecessary if according to the invention when transmitting speech, but not music, the deep Tones lowered so far compared to the middle tones or the high tones opposite the middle tones are raised so far that the speech when receiving, in particular with the usual radio receivers with bass boost, does not sound dull.

Auf diese «'eise wird die Verständlichkeit der Sprache erhöht. ohne daß der Rundfunkhörer den Klangfarbenregler des Empfängers heim Empfang von Sprache auf hellere Wiedergabe stellen muß.In this way the intelligibility of the language is increased. without that the radio listener uses the receiver's tone control for receiving speech must put on lighter reproduction.

Zur Durchführung der Erfindung ist es am einfachsten, zur Sprachwiedergabe ein Mikrofon zu verwenden, welches die tiefen Töne schwächt und" oder die hohen Töne bevorzugt gegenüber den mittleren Tönen aufnimmt.The easiest way to carry out the invention is for speech reproduction to use a microphone that weakens the low tones and " or picks up the high notes over the middle notes.

Für die 1Zusikwiedergabe wird dagegen ein anderes Mikrofon verwendet, welches den Tonfrequenzbereich möglichst gleichmäßig aufnimmt.On the other hand, a different microphone is used for 1 which picks up the audio frequency range as evenly as possible.

Statt mittels des Mikrofons kann die Beeinflussung der Frequenzkurve auch durch entsprechend bemessene elektrische Filter erfolgen, die bei der Sendung von Sprache eingeschaltet werden.Instead of using the microphone, you can influence the frequency curve also be done through appropriately sized electrical filters that are included in the shipment be switched on by language.
