This depends on a lot of factors like distance, direction, and original intensity. But it can be painful or worse, cause permanent hearing loss.

All good info. A bit outside of this post context but helpful nonetheless.
Good advice but the respirator doesn’t wrap around the ears so in the context of acoustic protection/reflection it doesn’t seem effective. I agree that a shield is conspicuous… I’m just spitballing about total effectiveness in theory. I like the end of the video shared above where the concave parabolic shape of the shield (when reversed) was used to redirect the LRAD sound at the operator. Pretty cool seeing a vulnerability in a system exploited in that way.
Thanks for sharing this video! It’s a great resource. $5 shop headphones and a polycarbonate shield you can make for under $100 beats a $20,000-$100,000 LRAD. I wonder if ear plugs, shop headphones, and a shield would be any more effective.
This is in Turkey, not the US. Also not TikTok employees but Telus Digital employees. Shit headline.
Maybe take a look at CanI.RootMy.TV. Seems to be mainly focused at LG WebOS but I’m not sure what vendor, model, and firmware you’re running. If you provide some more specific information you might get some more helpful answers for the situation you described. I totally respect that you might have left some detail out for privacy.
Predicting Trump and co are going to start saying Wall Street went woke and corporate boards are being paid for their opposition by China and George Soros. All the greatest hits.
I literally just deleted one of these texts before reading this post. Started seeing a lot more of these after creating a LinkedIn account… hmmm.
I found an informative post about a related issue that might be of some use to you. Sounds like DHCP or Network Manager may be rewriting your systems-resolved.conf.
Have you tried deleting /etc/systemd/resolved.conf and restarting the service with systemctl restart systemd-resolved?
Did you undo the reverse path strict filtering your guide suggested?
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.all.rp_filter = 1
Above is what the guide suggests to force reverse path strict filtering. Try setting as shown below:
net.ipv4.conf.default.rp_filter = 0
net.ipv4.conf.all.rp_filter = 0
According to the guide, “By default, these are set in /usr/lib/sysctl.d/50-default.conf”
Fair points! I’ve been tinkering with Homeassistant for a while now. The community has come very far so I’m hopeful that more advanced features will be added as the user base grows.
Yes, the voice recognition is decent. I mainly wanted a way to control some smart light switches without using a Google device. If you’re looking for something more advanced I don’t have any experience using his tool in that use-case.
Have you heard of Ollama? It’s an LLM engine that you can run at home. The speed, model size, context length, etc. that you can achieve really depends on your hardware. I’m using a low-mid graphics card and 32GB of RAM and get decent performance. Not lightning quick like ChatGPT but fine for simple tasks.
Have you heard of Homeassistant? It’s a self-hosted smart home solution that fills a lot of the gaps left by the most smart home tech. They’ve recently added and refined support for various different voice assistants, some of which run completely on your hardware. I have found they have great community support for this project and you can also buy their hardware if you don’t feel like tinkering on a Raspberry Pi or VM. The best thing (IMHO) about Homeassistant is that it is FOSS.
Here’s an article with a bit more detail… but I’m still unclear whether these backdoor commands are hardware circuits or firmware logic.

Debian is one of the largest GNU/Linux variants out there. Who and what you trust are personal decisions but they’ve got a good reputation.
