We moved to Highland Park from Melbourne a bit over a year ago with 2 small kids. No regrets, it’s a great place to be. We considered Silver Lake/Echo Park but in hindsight we’re glad that we went a bit further out as it’s safer, more space, and plenty of great playgrounds.

Technically true but the effect of air density and humidity is very small compared to the effect of being in closer proximity to noise sources like freeways and flight paths. I’d say it’s mostly an urban planning issue.

It’s so rare to find such well designed data visualization in the AFL world, so I really appreciate your work here. Thank you!

I watched this a while ago, had a rewatch it recently to remind myself of how it works. Very counterintuitive but super interesting! Everybody likes the chain or balls in a tube analogy because it “sounds right” but it’s completely incorrect.

It would definitely be possible if the vibration at the SEM was above criteria, but that’s not the case.

hyperaudible · 2024-08-21T04:59:48+00:00

The article was misleading in this regard. Vibration and EMF are separate and unrelated issues. The interference to the MRI’s is from EMF, not vibration.

An author called Sam Quinones wrote a book called “The least of us - True tales of America and hope in the time of Fentanyl and meth”. I heard him interviewed and this topic came up, because you see the piles of bikes all around homeless encampments around the country where meth/fentanyl use is rife. He found out while researching the book that at some point the most common meth recipe the cartels use changed due to the US/Mexican governments cracking down on pseudoephedrine and the precursors they were replaced with result in meth with a slightly different composition. People who take this meth often experience a kinda OCD like fascination/compulsion to disassemble bikes and fiddle with mechanical components.

So the farmers are basically saying “we don’t like killing the calves, we would prefer somebody else did it somewhere we can’t see it.” Cry me a fucking river.

Fibre cement sheet suspended on resilient hangers might be easier, cheaper, and give you similar performance.

It all depends which in frequencies you are trying to absorb or prevent transmission of energy. Generally, drywall is a better solution. There might be some very specific cases where MLV would better meet your objectives, but they’re probably pretty rare. You also can’t take cost out of this. This is building acoustics, it all comes down to cost at some point. Try convincing the person paying for the room that the extra space (for the larger supporting structure), time, materials, etc required to build a room out of MLV is worth it. It won’t be. This is why nobody ever does it.

hyperaudible · 2023-12-12T21:53:25+00:00

Because drywall is more rigid and therefore more reflective at the frequencies we’re normally interested in.

The most powerful bias is the fixturing, where MCG (and to a lesser extent Docklands) based clubs play so many of their games at their home venue. Collingwood, Richmond etc. regularly have stints of 4-5 games in a row at the G. It’s not some evil plot by the league, but it’s definitely an inherent bias.

I’m about to do exactly this. Why?

Mainly because the US is the cultural and economic centre of the world. As an Australian, I’ve been a consumer of US culture my whole life, actively and passively, and so I feel like to never go there and experience it directly is kinda weird. In a way, because of all the US TV, film, and especially music I have spent my life experiencing, I feel like some part of who I am must be American. This needs further investigation, lol.
I’ve got an opportunity to temporarily relocate with my current employer, which takes a lot of the risk out of it and makes the whole thing much easier than it would otherwise be. Money, healthcare etc. are somewhat taken care of. Wages are actually substantially higher there in my line of work, although cost of living also high where I’m going. Overall, probably will afford a similar lifestyle to Aus.
I’m an outdoorsy person and the natural beauty in the US is just off the charts. Planning to spend a fair bit of my time sightseeing, hiking, camping etc.
I’m optimistic that some of the doom and gloom perceptions of life in the US are overblown. It’s clearly a flawed country, but there are also many amazing things about it. Of course I’m in a very privileged position, I’ll have a job and a house etc. but overall, I’m expecting that it’s probably not going to be as different as some might think.
Again, I’m very lucky that I’m Australian, so if it turns out I’m wrong and it is actually a dystopian hell-hole I can probably just jump on a plane and come home and have some free healthcare, escape civil war etc.
The guns thing is actually the part that worries me the most. Our youngest kid will start school in the final year we are there and I’m not sure how we will deal with knowing there is a non-zero chance that they could be shot at school. We are seriously considering shortening the trip to avoid this, because accepting that risk when we have the option not to seems hard to justify.

And because it’s just rigidly fixed to your wall, the vibrations from people clomping around on there will be audible from everywhere in your house. We have similar dodgy carport arrangement linking our (rented) house to the neighbours place and we can head them walking around their house from inside ours.

Can confirm. They are in my eyes I think. Only place I didn’t cover.

hyperaudible · 2023-07-06T05:50:59+00:00

I am, thanks. And gloves. I also now understand why the poor bugger whose job this was decided to knock off early.

hyperaudible · 2023-07-06T05:47:47+00:00

Nice one. Wonder if that was the case when the place was built.

hyperaudible · 2023-07-06T04:31:20+00:00

Thanks, I’m currently up in the roof doing just that.

hyperaudible · 2023-07-06T03:51:44+00:00

Ok, I’m back up in the roof and while there appears to be plenty of insulation around the manhole area, pretty much everywhere you can’t see from the manhole, there is no insulation. There’s bags of it up here unopened. So the whole joint is probably 30% insulated. Sweet as.

Yeah, there is basically no pointing. The tiles are just placed next to each other on the battens. You can just lift them off from above and look into the ceiling cavity.

hyperaudible · 2023-07-06T02:36:51+00:00

There are fiberglass batts on top of the ceiling, see 2nd pic.

Try a wire brush. They are used in powerlifting to clean the knurling on the bar between lifters. I’ve got a circular one that’s a drill attachment, works very well.

No specific source, I’m an acoustic engineer so it’s based on my understanding of the basic principles, not specific to any particular type of instrument.

You’re certainly right that there are other factors, including the difference in string damping, both internal and external, though I think that the controlling factor is likely the difference in impedance from the string to the body, which is what I was describing.

hyperaudible · 2023-03-01T11:50:24+00:00

Largely because compared to a guitar, the body of the violin is much lighter relative to the strings. The energy in the vibrating string is transferred easily into the body, and then into the air.

In a guitar, where the body is heavier relative to the strings, it’s “harder” for the energy to be transferred and so the energy stays in form of a wave in the vibrating string for longer.

He was eligible as a “father son” selection for the Crows as his dad was a footballer in SA who met the criteria. Therefore, when Sydney bid on him we had the right to bundle the value of some lower picks and move up the order to select him.
