Abstract

Bei einem Verfahren zum Erzeugung von Geräuschen, insbesondere von Schaltgeräuschen, ist vorgesehen daß Frequenzwerte sequentiell aus einem Speicher (1) ausgelesen werden, daß entsprechend der ausgelesenen Frequenzwerte elektrische Frequenzen erzeugt und mittels eines Schallwandlers (4) in entsprechende Schallwellen umgesetzt werden.In a method for generating noise, in particular Switching noise, it is provided that frequency values sequentially a memory (1) can be read out in accordance with the read frequency values generated electrical frequencies and by means of a sound transducer (4) converted into corresponding sound waves become.

Bei einer Vorrichtung zur Erzeugung von Geräuschen mit dem vorstehenden Verfahren, ist vorgesehen, daß sie die folgende Einheiten umfaßt:

  • eine Speichereinheit (1) zum Speichern von Frequenzwerten,
  • eine Frequenzerzeugungseinheit (3), die Frequenzen entsprechend eingelesener Frequenzwerte erzeugt,
  • eine Verarbeitungseinheit (2) zum sequentiellen Auslesen der Frequenzwerte aus der Speichereinheit und zum sequentiellen Einlesen in die Frequenzerzeugungseinheit (3)
  • eine Wandlereinheit (4) die mit den in der Frequenzerzeugungseinheit (3) erzeugten Frequenzen angesteuert wird und die erzeugten Frequenzen in Schallwellen umwandelt.

A device for generating noise using the above method is intended to comprise the following units:
  • a storage unit (1) for storing frequency values,
  • a frequency generation unit (3) which generates frequencies in accordance with read-in frequency values,
  • a processing unit (2) for sequential reading of the frequency values from the storage unit and for sequential reading into the frequency generation unit (3)
  • a converter unit (4) which is controlled with the frequencies generated in the frequency generation unit (3) and converts the generated frequencies into sound waves.
