Absorbing traffic noise with Helmholtz resonators (video)

Now imagine many tubes bottles ( 100 ) ,with various neck volume and lenght, from 8 foot to few inches, all tuned and located on the right spot (some near the speakers woofer or tweeter others beside or near me and some near wall reflecting location ) ...😁

I miss my crazy room where the soundfield were completely holographic as a completely surround system i even use foldable screen with devices on them etc ...

Now i am in near listening in a smaller acoustic corner but my system speakers are more accurate in the high  frequency response than my bigger Mission  and  because i modify the porthole design and the waveguide then i improve the bass and medium so much  i am glad too... And my headphone modified gave me a speaker soundfield... Then i enjoy 2 systems instead of only one now...

Helmhotz is the greatest modern acoustician...😊 I will put dr. Choueiri beside him ... And Dr. Gorike founder of AKG and the designer of my hybrid headphone : akg K340 ...

Fun experiment. Thanks Mahgister👍

Incredible important information... Thanks Hilde...

I think my research are motivated among other papers by this Russian Paper of 2017...I just begun this video about Helmholtz resonators too ...

I used 100 tuned Helmholtz resonators in my past room... The results were stunning with a soundfield filling my room and the speakers were disapearing... I used also many others devices though to contribute to this as experiments.

Incredible information in this video about the increase of heart pressure and 10 decibels of sound too much...

I used also many Schumann generators ( low cost) 13 of them and it is easy to spot the impact when well located in the room or near the gear...

I stopped talking about these here because too much idiots harassed me with insults... I am not patient then i reacted too much....😁

But with this interesting information to study i will be able to talk about this anew if necessary ...

Thanks hilde45....
