hola esa pagina acambiado o lo han eliminadopor que ya no se encuentra, me ematado buscando ...lo mecionado... si alguien sabe alguna actualizacion les agradezco por el aporte muchas gracias.

So will your rockwool or insulation affect the depth of your box or no?

Excelente explicación, gracias

Just put Fiber Glass in pillow cases and Hang on the walls works better than a Frequency Specific box.

que tipo de tela usaron para cubrir la fibra de vidrio?

Can you repost the link? I don’t think it’s working anyone

hola, consulta, la pagina de Mh Audio me aparece caída en argentina, algún consejo e como puedo hacer el cálculo con algún software?

Excelente explicacion pero el link no funciona

Hola, al rededor de 100 hz con cuanto ancho de banda quedan los paneles?

Is that link still active? I can't get it to work.

Highly interesting content, and good explanation. I like that it goes nerdy 🤓 Please keep up the good work - post some more videos in English 🙏 Next video could be about membrane bass traps 😉😋 PS: you should respond to the questions by commenters here. Even if a long time ago, cos others may read it and wonder about the same things. And by responding you show that you care about your viewers 🌸

Do I understand this correctly, that 100x40x40cm (in your case) are the EXTERNAL measurements? At 6:15 it looks like a 40x100 panel was placed on the bottom, on it two panels and on them the last panel. That makes for a rectangle of external dimensions of 40 x 44cm and internal dimensions of 36x40 I think those calculate dimensions were meant to be internal, (it says so on the acoustic calculator site), to make a volume V=0,16m^3, and also added to that is glass wool, which also has volume - does that not need to be compensated for? For every 1kg of glass wool, you'd need to increase the chamber by 0,004m^3 to internal dimensions of 100x40x41cm.

Excelente. Espero con ansias más contenido. Sería genial que ahonden el tema de como tratar acústicamente cuartos con dimensiones cúbicas, casi no hay información en Internet o prácticamente no la hay. Si existe algo de literatura, agradecería mucho si pueden compartir cuál es. Saludos desde México (desde mi habitación cúbica).

Thanks! Very useful!

cuantos litros de fibra de vidrio usaron ?

Nice, you should however add the source name for your pictures eg: "Master Handbook of Acoustics".

Hi, thanks for the video. I didn’t understand about filling it with rock wool part. Do you fill the whole box with it? Or do you leave some space? Could please let me know. Thanks again!

Hola muy buenas recomendaciones y explicaciones. Pero tengo una duda... Podré fabricar un resonador pero de forma triangular para las esquinas de mi sala ???' se aplicarían las mismas fórmulas, al no ser rectangular o paralelas ???

Glue guns aren’t silicone, they are a hardening material which themselves have a resonant frequency.

Hi Im an Architecture student and I wanted to know how you could INDUCE sounds or ‘music’ using winds. Can we use helmholtz technique or anything else to walls or to the structure of my building in order to make calming music from winds…? Also love your work! Also really appreciate your help🤗

Oh my god ....glad that you made thsi video !!!! Thank you !! 😅

Exelente explicación, muchas gracias de verdad, me surge una pequeña pregunta, como se cuantos resonadores necesito para el espacio donde quiero colocarlo, con solo uno es suficiente o son necesario mínimo 2????

Let's build Helmholtz resonator!

women are in a scoeity of resonance

Brilliant video!

this is so bad, never use glasfiber or rock wool, they are the new asbestos, just buy cold foam 5 cm and it will also work and keep you longs oke

Did it work? EDIT: I've just seen that your depth of air space is not 40 cm, because you have a thickness of 2cm on the back and the front, so it would be 36cm. It states it in the website that it is the space from end to end of the empty space, rather than the outside of it. Unless I'm missing something and you got it right? This is what it says on the website Notes: the depth of the air space is the internal depth of the box, the distance from the inside of the panel with the holes/slats to the inside face of the rear panel. The panels themselves are not meant to move at all, therefore you should make them out of a material sufficiently thick so they don't move. Don't use 6mm MDF! If you're going with < 16mm MDF then you might like to put in a couple of braces - nothing ridiculous, just to stiffen the panels up a bit.

Id probably put silicone in between wood joins so the box is air tight.. I think I might make some Helmholtz furniture that way the space does not go to waste..

Hola, gracias por la información pero tengo dos dudas, la distribución de los abejeros debe tener un orden?, y saber qué densidad de la lana de roca recomiendan, necesito trabajar los 100 hz igual. Gracias

Mil gracias !

hola buenas, queria saber que libro utilizo para los ejemplos??

How much rockwool do you put in each resonator? 50mm, 100mm... Or try to fill it right up?

If you have a say 38Hz peak problem you use the Helmholtz resonator. What do you use if you have a dip say 49Hz? No treatment for that only change listening position or shift speakers position or angle or ??

Muy interesante el video, me saltan algunas dudas: ¿Tendrán la respuesta del cuarto, antes y después? ¿En que lugar y en que posición se pusieron los resonadores?

Exelente, gracias

!!! EXCELENTE!!

Noté que la lista de materiales está en español, ¿pueden hacer un vídeo en español de este mismo tema? Sería increíble y les estaríamos enormemente agradecidos

Thank you

I recommend : getting wood fibre insulation instead of the RockWool/Glass fibre insulation, Like the ones from Steico
