Noise-Cancelling Headphones actively cancel external sounds so the listener can hear their media without distraction. Comment below and let us know your experiences with noise cancelling headphones and any alternatives you’ve come up with. In addition, the better noise cancellation headphones use both feed-forward and feedback (Bose pioneered this) .
Use Peltor shooting ear defenders, they’re superb, and the same shells as used for rallying headsets.
For an even easier hack, just use your favourite set of earbuds (or earphones) and wear the industrial ear muffs over top. Of course it was completely against every single safety rule but that didn’t stop anyone. If you listen to music you won’t be able to hear someone screaming at you to move out of the way when something heavy comes your way. I actually started this project with a bluetooth headset but one of the earphones wasnt working.
Also many saws have a braking feature (like chop saws) that works by shorting the motor, which generates even more RF hash. I bought a set for ?25 ($40) (powerfix pkg 82 a1) which had an FM radio built in for a long haul flight. They have a microphone which allows you to hear when someone speaks to you despite the noise from any power tools you may be using.
Unfortunately they do gunk up a bit with earwax, and if you pull them out too quickly, they can separate leaving the foam deep in you ear. In my experience with headphones, passive noise cancelling headphones have always been more effective than active.


Also relevant, some BT headsets can be macgyvered by replacing the e2prom, synchronising power-up and a few other tricks. I have made the same modifications to my military grade earprotection (issued by Finnish defense forces). The feedforward arrangement of noise cancellation (mics on the outside of the earbuds) will get you a few a few dB of attenuation at low frequencies, but the response *must* be appropriately EQ’d. It’s pretty much standard practice to ban music where heavy machinery and people meet for this reason.
In the wood shop, Just the NRR 30 ear muffs because it’s important to be able to hear how the wood is cutting and the sound of the motor. Red ear protectors like that used to be $3 at Harbor Freight, but I can’t find that pair on their website now.
I was completely oblivious to anything going on around me, even with the sound turned down. I’d make a large bet than wearing canalphones under unmodified earmuffs would give you better sounding music and higher isolation for cheaper than the parts used in this hack.
100usd and they are made to work in loud environments and are acoustically better than cutting and gluing. There is one downside to these types of noise-cancelling headphones, they are very expensive. Make some headphones that will block out the noise but still allow the comfortable listening of music.
The acoustic response through the earcup is not flat and if you don’t account for this you will certainly end up amplifying some frequencies (overcorrecting).
Feedback gains you quite a bit more attenuation, but if you don’t EQ it appropriately and tune the gain you risk getting feedback.


The only exception is when planing lots of bf, when I use the foam in-ear plugs, plus the ear muffs.
A couple tips to improve the build quality: Use a dremel or something to cut a couple of small slots in the bottom of the plastic shells and hot glue the cords in the slots for stress relief. Not saying the hack was pointless, maybe the hack-er finds canalphones uncomfortable or just wanted to learn about active noise cancellation. This project is simple but effective; inexpensive headphones taken apart and installed in a pair of Industrial Ear Muffs.
Hot gluing the drivers and foam pads inside the shells so they stay put is also not a bad idea.
