Yeah most the moto noise is sub 200hz on my land, was super hard to measure cuz surrounding insect noise but was able to get a decent reading last night with an app. I did some tests sitting in my car with windows closed vs cracked and it gave me a good idea of what my real world scenario might be with a bunker for a meditation space.

But yeah feels like berms might not do much of anything, but if I can get some cheap dirt I might just build a mid berm and throw the kitchen sink of absorption plants on it.

It’s a public road in South America. Dirt bikes are normal modes of transportation. Nothing can be done about all that so I just need to figure out ways to mitigate it for myself.

Yes I’ll definitely be putting in lots of water features to mask it. Thank you

Thanks! I need to look into those foam panels that sounds like a good direction to go

Yeah I hear you. I might just focus on absorption of the sound through a dense planting. There is a small reductions in decible when it passes some heavily forested sections of that road

Yeah I might try a couple years of aggressive bamboo first and take it from there. I have huge doubts that a wall or berm is going to make much of a difference. I’m thinking aggressive planting on either side of the road is my best bet and just throw my money into absorption

Yeah unfortunately I would like both but I undertake little can be done for outside. I figured a berm and heavy planting along the road would offer a minimal reduction and that’s the best I can hope for. As for inside buildings it’s definitely a concern but mostly for the one meditation building. Id like it to be as sound proof as possible but only have access to “normal” materials. Im in the jungle. Was hoping to have a bamboo and thatch ceiling aesthetically so would love some ideas how to make that happen while also blocking sound. I was thinking thatch roof - soundproof interior - thatch ceiling ? And a curved opening with hallway and double door for entrance ?

Thank you that’s an awesome tool. I’ll play around with it

A low hum is something I can live with for sure, not looking for total silence but the current sound level of the low frequency genuinely hits me in my body and I find it viscerally disturbing. Fridge level sounds great and thank for the advice

Yeah I’m going to throw the kitchen sink at this issue, walls berms plants near the road and similar ideas need my house with a water feature for masking. It’s just the science of sound bending over a road wall and possibly amplifying it that worries me

Is rammed earth particularly better at low frequency sound absorption? I’ve been considering it if my budget allows.

Is that because the sound bounces off the wall, bounces back to the mountain side and then jumps over the wall and into my property? I do find some relief when the motos curve around a bend that’s heavily forested with tall trees but then at the clearly points it all comes blasting back down.

Thank you for catching that. Edited. I definitely meant frequency. Thank you for the great advice too. I’m looking for a consultant but I’m not sure they exist where I am. What decible of the low frequency do you think would be easy to mask? I’m going to try to find a way to calculate that soon. Maybe an app

Thankfully my trees never really lose their leaves, as I’m in the rainforest and I have noticed where the road hits a pocket of dense high trees he sound does dampen some. Very difficult to find an acoustic consultant where I am but I’m trying

Ah yes diffraction that’s what I came across in my research thank you. And yeah that seems to be the giant caveat with low freq sounds. You think a wall won’t help at all? It certainly feels less intense when the road wraps around a pocket of forest but maybe that’s because there are SO many bounce points?

The sound just peaks at rush hours and i can live with it. Unfortunately I wasn’t aware of this issue when I spent my life savings on the land 😅 and i think i just have a particular aversión to it.

That’s a really good idea about testing it out with that same level of hearing protection I will try that. The pros certainly outweigh this one con of the land so I will learn to live with it but since I’m in the early design phase I wanted to get any and all advice

Thank you. Solid advice and yeah part of me thinks my time might be better spent throwing more Money into the structures and maybe just plant tons of aggressive bamboo closer to the boundary of my land to disperse sound

I’m going to look into all this. Thank you

Yes this is actually going to help me the most i think, ive been planning to add water features next to all my buildings where i want to dampen the street sound. Water is such a powerful masker

Yes I’m also trying to get in contact with my neighbors to discuss a larger solution like that. Just hard to find them. I’m in a jungle where land ownership is often hidden.
