Active noise control example code

Hello!

 

I am trying to implement the example code for Active noise control in LabVIEW on a experimental setup with two speakers and a microphone. I need help in the setup conditions (distance from speaker to speaker) and also I am using TEDS sensors so I need to add the TEDS sub.vi into the code. Has anyone conducted such an experiment using the Active noise control example .vi?

 

Thank you!

I hope you're talking about the cRIO example because the other one is just a simulation.

 

In that case, the documentation of the VI specifies how to space the speakers and microphone, HW requirements etc.,

Dear Santhosh,

 

thank you very much. You're right, I am talking about that example. I have placed the hardware right, but I was wondering how "small" is several centimeters in distance between the speakers and also, should the zone between the speakers be isolated totally from the environment. I am asking this because according to the literature references I have used in active noise control in experimental ducts, all the examples are conducted in ducts with length around 1 meter and isolated. Also, I am using TEDS sensors as sound sensor and I am having concerns if the TEDS .subvi is correctly connected and implemented into the host.vi. Would you mind taking a look into my project and see if you find a mistake somewhere, because somehow I don't happen to obtain noise cancellation even though the FPGA .vi is correctly compiling and the host .vi works fine.

 

THANKS!!!
