A few speaker180 degree out of phase.
If you want mount on the fence, you can use tactile transducer, same 180
degree out of phase. It might require some testing to perfect this. That is
what I use to cancel the sound from my home theater room. I have over 3000
watts (one 400 watt amp for each channel) for the theater, I used about 20
tactile transducers mounte | t*o 发帖数: 2606 | 2 发信人: gezhi89 (zhonda), 信区: Living

I use this brand.

I bought a few cheap low quality amps to drive them.
I used 2 mic in my set up to pick up the noise and send it back 180 degree
out of phase to cancel.
I have to fine tune each frequency a little bit to get the result you want.
I am basically vibrating the walls to cancel it.
You can use a outside mic and indoor mic to analyze both soun |
