6. Erklärung den Empfängern6. Statement to Recipients

Die 1 Empfängern verteilen im Auto in verschiedene Stelle und auf verschiedene Zahl.The 1 receivers are distributed in the car in different places and on different numbers.

Um den Empfängern richtig verteilen soll ich das Auto in folgenden Teil verteilen:

  • 6.1. Der erste Teil: Er ist vorne und enthaltet das Glas vorne, das Motor und den Lärm oder Regen von außen solche Richtung
  • 6.2. Der zweite Teil: Er ist vorne Linke in Fahrerseite und er enthaltet das Rad, das Motor und Lautsprecher sowie der Lärm von außen solche Richtung,

In order to distribute the recipients correctly I should divide the car into the following part:
  • 6.1. The first part: it is in front and contains the glass in front, the engine and the noise or rain from outside such direction
  • 6.2. The second part: It is in the front left on the driver's side and it contains the wheel, the engine and the loudspeakers as well as the noise from outside such direction,
  • 6.3. The third part: He's right behind the wheel. It includes the engine, hazard lights and turn signals.
  • 6.4. The fourth part: It is in the front right and it contains the wheel, the motor and the loudspeaker as well as the noise from outside such direction.
  • 6.5. The fifth part: It is the driver's side door and it contains the speaker, the glass, the engine, the wheel and the noise or rain from outside such direction

7. Erklärung die Akteure (der Korrektor)7. Explanation the actors (the proofreader)

Die Akteure sind verteilet neben den Empfängern aber nur von innen Seite (das Cockpit des Autos)The actors are distributed next to the recipients but only from the inside (the cockpit of the car)

8. Erklärung der Funktion8. Explanation of the function

Der Raspberry nimmt alle Dateien, die von den Empfängern sowie Ressourcen kommt, auf, dann vergleicht er zwischen den Schallwellen um die übrige Welle, die wir nicht wünschen, dann sendet den Raspberry die Anweisungen zum entsprechenden Akteur um das Geräusche zu löschen.The Raspberry takes all the files coming from the receivers and resources, then it compares between the sound waves around the rest of the wave we don't want, then sends the Raspberry the instructions to the appropriate actor to cancel the noise.

9. Mehr Erklärung über der Funktion:9. More explanation about the function:

Lassen Sie uns bitte nur eine Seite diskutieren wie der zweite Teil (Der zweite Teil: Er ist vome Linke in Fahrerseite und er enthaltet das Rad, das Motor und Lautsprecher sowie der Lärm von außen solche Richtung) und nur eine Sorte ein Geräusch wie die Geräusche des Motors:

  • Der Raspberry sammelt die Dateien über den Empfängern und Ressourcen 9.1. Die bestehenden Ressourcen:
    • 9.1.1. Der Raspberry verbindet sich direkt mit dem Lautsprecher (vorne links) um die Welle im Hintergrund eintragen
    • 9.1.2. Der Raspberry verbindet sich mit einem Aufnehmer/Empfänger (wie mic) neben dem Lautsprecher (vorne links) um die Welle im Hintergrund eintragen. 6
  • 9.2. Die notwendigen Ressourcen, die von außen sind. Der Raspberry verbindet sich mit einem Aufnehmer/Empfänger (wie mic), dem draußen (vorne links) installiert um die Welle von der Rettungsdienstwagen im Hintergrund eintragen. 7
  • 9.3. Den Empfängern:
    • 9.3.1. Der Raspberry verbindet sich mit einem Aufnehmer/Empfänger (wie mic), dem neben dem Motor (vorne links) installiert um die Welle, die vom Motor kommt, im Hintergrund eintragen
    • 9.3.2. Der Raspberry verbindet sich mit einem Aufnehmer/Empfänger (wie mic), dem innen (vorne links) installiert um die Welle, die vom Motor kommt, im Hintergrund eintragen. 6
Please let us discuss only one side like the second part (The second part: It is from the left in driver's side and it contains the wheel, the engine and speaker as well as the noise from outside such direction) and only one kind of noise like the noise of the motor:
  • The Raspberry collects the files via the receivers and resources 9.1. The existing resources:
    • 9.1.1. The Raspberry connects directly to the speaker (front left) to record the wave in the background
    • 9.1.2. The Raspberry connects to a pickup/receiver (like a mic) next to the speaker (front left) to record the wave in the background. 6
  • 9.2. The necessary resources that are from the outside. The Raspberry connects to a pickup/receiver (like a mic) installed outside (front left) to record the wave from the ambulance in the background. 7
  • 9.3. The recipients:
    • 9.3.1. The Raspberry connects to a pickup/receiver (like mic) installed next to the motor (front left) to record the wave coming from the motor in the background
    • 9.3.2. The Raspberry connects to a pickup/receiver (like mic) installed inside (front left) to record the shaft coming from the engine in the background. 6

Der Raspberry jetzt hat die Wellen von den Geräuschen des Motors von den beiden Seiten (innen 1 & 6 und außen 2) schon im Hintergrund und er hat diese Welle ausgewählt, da die beiden Wellen ähnlich sind. Die Geräusche des Motors ist das Fazit der beiden Wellen. Jetzt darf den Raspberry eine Welle gründen und zu den Akteuren (der Korrektor 8) senden um die Geräusche des Motors zu lösche, aber beachten Sie, dass die Welle, die den Akteur auflösen darf, ist genau das Gegenteil der Welle, die vom innen Aufnehmer (3) und ein Teil von dem Fazit kommt. Eigentlich das System macht die Funktion regelmäßig sofort ohne Sekunden-Wartung.The Raspberry now has the ripples from the noise of the motor from the two sides (inside 1 & 6 and outside 2 ) already in the background and he chose that wave because the two waves are similar. The noise of the engine is the conclusion of the two waves. Now the Raspberry can start a wave and go to the actors (the corrector 8th ) send to cancel the noise of the engine, but note that the wave that is allowed to dissolve the actor is exactly the opposite of the wave sent by the inside pickup ( 3 ) and part of the conclusion comes. Actually the system makes the function regularly immediately without any seconds maintenance.

Das System bekommt die Wellen des Rettungsdienstwagens von außen über Aufnehmer/Empfänger (wie mic, 7), aber der Raspberry grübt keine GEGENTEIWELLE und das bedeutet: der Fahrer hört diese stimme, wenn er rein im Auto, da den Raspberry sie erkannt hat, da den Raspberry hat auf die Haupt-Wellen programmiert (wie die Geräusche des Motors und Die Autoradiomusik)The system receives the waves from the ambulance from the outside via sensors/receivers (such as a mic, 7 ), but the Raspberry does not dig an OPPOSING WAVE and that means: the driver hears this voice when he gets in the car, because the Raspberry has recognized it, because the Raspberry has programmed to the main waves (like the sounds of the engine and the car radio music )

Das System arbeitet regelmäßig zusammen um die Wellen von den Ressourcen (Autoradio, Warnblinker Blinker usw.) im Hintergrund sammeln, damit den Raspberry eine Welle Gegenteil nur die ungewünschte Welle gründen um die ungewünschten Geräusche zu löschen.The system regularly works together to collect the waves from the resources (car radio, hazard lights, turn signals, etc.) in the background, so that the Raspberry creates a wave opposite only the unwanted wave to cancel the unwanted noise.

10. Welche Probleme hat das System Anti-Noise?10. What problems does the Anti-Noise system have?

  • 10.1. Eigentlich kann das System Anti-Noise kann max. 40% das Geräusche löschen und reduzieren, wenn das Auto in der Stadt fährt wegen der folgenden Gründe:10.1. Actually, the anti-noise system can cancel and reduce the noise by max. 40% when the car is driving in the city because of the following reasons:
  • 10.1.1. Es gibt in der Stadt viele Geräuschen, dessen die Wellen zusammen mixen lassen.10.1.1. There are many noises in the city that make the waves mix together.
  • 10.2. Das System Anti-Noise kann max. bis zum 65% das Geräusche löschen und reduzieren, wenn das Auto in der Stadt fährt wegen der gleichen Gründe in 10.1.1.10.2. The Anti-Noise system can eliminate and reduce noise up to 65% max. when the car drives in the city for the same reasons in 10.1.1.

11. Was ist das Ziel des System Anti-Noise?11. What is the aim of the System Anti-Noise?

Die Geräusche im Auto, die was den Fahrer hört, wenn er im Auto ist, reduzieren.Reduce the in-car noise that the driver hears when in the car.
