Thanks again Greg,
One final question I would just like to ask for my project planning. Should I consider active noise control as an option. In principle I know what needs to be done, but in practice active noise control seems to be not so easy. I am working with noise from a duct so much more...
Thanks Greg!
I like the piston idea easier than cutting and capping for accurate tuning. Any advice on finding the positino of maximum pressure? I have pretty limited resources here so far I am using a off the shelf microphone (karaoke mic actually), mini amplifier and my o-scope with an FFT...
Hello all, I'm new to this group so forgive me if I ask newbie questions.
I understand the basic physics of 1/4 wave tuners etc. (from electical and RF work) but now I have the problem of reducing the noise from a blower fan and need some practical guidance.
Problem is a noisy "leaf blower" fan...
