Soundproofing my Apartment that is Next to Train Tracks - WFH

It’s so effective that after your soundproof door and window was installed I can only hear from my left earphone! Woah!

It's going to be practically impossible to block out the noise from the train. 1) the lower the frequency, the harder it is to block off -- that's why you can hear your neighbours bass beats but not the entire song 2) the power generated by the passing train would cause even the surrounding buildings (including yours) to vibrate, effectively turning the walls into a diaphragm; essentially turning them into bass speakers.

-20 db difference it's quite impressive. Keep in mind that -3 db means about twice less sound pressure. Once you add a second door to the existing one that goes to your laundry you should see a much bigger difference. Also, the sound goes through your building walls which means that you will hear the train anyway. If you go to a no sound room you end up hearing your heart beat, because our ears adapt to ambient noise. Overall very good video! 👍

Consider these getting/changing the following: - get a acustinc curtain for night time, it should further reduce the noise - replace that door [ideally the whole frame too, its too old], also when getting a new door most are hollow in the inside, so try getting a solid one theres few more options, but these should improve the sound isolation

What a spectaculair view you have man! I love it. Always much dynamic. It would look even more amazing when it's dark I guess. My window looks at the big green barn door across the street. That's it. And it also blocks the sun.

Good video. Very informative. As someone who doesn't know much about sound, I was surprised that the ambient noise didn't reduce as much as I thought it would.

This is great. Ppl don't realise the stress traffic/transport noise causes. It cost €5000 to get 1 window done in my house and the window is not that big.

A significant improvement indeed

Did you post your video after the door sealing?

You can also layer the windows with loaded vinyl lined sound curtains and apply a payer of loaded vinyl to the exterior utility door, that should reduce the sound by an additional 10 decimals.

you could have achieved a -40db reduction like this: leaving the existing window in place, asking the cement guy to build an extra 10cm wall on the external side, and installing a double pane window into that: as a result you would have double windows (2 windows). The door towards the air-conditioner should be replaced completely. Thanks for the measurement!

Great video! Love the data, updates and graphs.

20db is 75 percent, that’s actually really decent. Also train noises are usually low frequency which are harder to block.

Hard to get totally quiet from that train as it’s probably vibrating from bottom of building the whole way up. Good job great improvement.

What app did u use to measure the sound and what company did you use for the windows and door

Did you change the wooden door to new soundproof door?

Is it upvc material for the window frame?

Hi mate thanks for this, seeing it in practice is really useful!

Great video. The door probably needs to be replaced with something much heavier, and maybe get a special door sweep for the bottom of it if there’s a gap. From my understanding, the two only factors for soundproofing are the mass (weight) of whatever is between you and the noise, and also blocking air leaks, since sound is just air pressure waves. If it’s a hollow type door (pretty common), you might look into “solid core” doors, and get the heaviest densest one you can find . Or they might even make special soundproof doors.

Which vendor u used for the soundproof windows?
