Dear colleages,


I have a fairly simple question to ask you about: what is the best active noise cancelling headphone on the market for lab-work environment?

We have many fans and few compressors in our facilities, which generate constant noise.

We have tried to cancel out the noise by using passive earplugs, but they don't totally block the noise, so we wonder if there's a better alternative on the active noise cancelling side.

Any suggestions?


Thanks in advance,

Very interested in this questions because I have found that Bose do an incredible job with lower frequencies, very little for mid-range voices and higher, no better than any over-the-ear headphones for sound from cell phone speakers, and nothing with sonicators and other high frequency emitters.  

Are there solutions for mid-range to 20+ KHz?

Hi Luis,
I haven't tried using them in the lab environment, but I've found Bose QC20 earbuds to have excellent noise-cancelling properties (particularly for low/mid frequencies) and, unlike the QC25s aren't too bulky.  The only downside is they are wired and have a small Lithium battery pack on the wire to power the active cancellation.  Bose QC30s are wireless equivalents, but from what I've read are not so efficient at noise cancellation.
Not sure about the health&safety implications of wearing noise cancelling headphones at work though (not hearing alarms etc.).
Simon

Just to add to Simons list, the Bose QC series are all great - top of the
line. They do come with a little heavier price tag than most - but from an
acoustic standpoint - they are the best.

If you are just looking to cancel out background noise, then there are some
cheaper alternatives with close to the same quality - Audio-Technica (ATH)
makes several noise canceling headphones (wired and bluetooth). The Samsung
Level On's are about half the price of a pair of Bose and are bluetooth NC
headphones.

Whatever you decide to go with, get "on-ear" or "over-the-ear" headphones.
They are far superior to "in-ear" buds, in both technical performance and
comfort (in my opinion).

Bluetooth has its obvious conveniences, but audio quality is typically not
as good and they are almost always cheaper than bluetooth.

Best of luck,

Luis,

I’ve had good success with Shure earbuds like the SE215 using the foam tips. The key is getting a good fit and seal. They work wonders on loud airplanes too! I don’t have any experience with the active canceling route.....it bothers my inner audiophile ;).

Hi,

I think a better approach for a facility might be to call an acoustic
control company and have a walk around in the lab. and identify the main
sources of the noises. They could do wonders. I still have the box a company
constructed for the 2 fans of the Krypton Argon lasers which reduces the
~70db noise to a hum (the lasers are long gone!). They also did some things
for the chiller for our TEM to make our lab space workable again. Noises and
the darkness in a facility give me headaches. This is the least you could do
for your users...

As to noise cancellation headphone, I have been a long Bose user and are
happy with it (both the Quietconfort 15 and 35). But both came without me
paying for it, I am sure there are better price/performance choices. I
cannot tolerate in ear headphones which is just me..

 I've had great luck with standard 30dB ear muffs.  Pretty comfortable,
reasonable price, excellent noise cancelling on all frequencies, no wires
or batteries, you can wear earbuds under them for podcasts and music, and
when you wear them people know to leave you alone.  Win win!

Hi Michael,

Active noise cancellation above 1-2 KHz is not very effective due to the
shorter wavelength.  However, the acoustic isolation of most materials
increases greatly above 1 KHz.  If you want to isolate higher frequencies,
tight fitting inner ear headphones (IEMs) can be extremely effective
(1000-fold attenuation or more).  Tightness of fit is key however, as any
air leaking around the edges will undermine the isolation.

For what it's worth, when I was aligning a microscope using a 4 KHz
resonance scanner at 25 degree deflection, the sound was deafening without
ear plugs.  However, just using a $20 pair of Creative EP-630s (about the
lowest quality IEMs you can buy) reduced the high frequency noise to a very
tolerable background human while I listened to music at comfortable
volume.  The key was to use the largest insert size they included, which
was very tight fitting and blocked out airflow entirely.  I'm sure if you
spent more you could get something even better.

If your budget allows then Sony WH-1000XM2 is probably the most advanced of its kind on the market. Actually optimizes on the fly and best of all it's wireless. I also echo the suggestion of others of a good custom in-ear-monitor but the costs could be prohibitive. What you can do instead is go to a hearing clinic and actually get custom in ear plugs (without the electronics) that may serve a better job than standard foam plugs. You can get them in silicone or acrylic.

Just a note that if you are getting these for employees, that in some
people, noise cancelling headphones cause a vertigo like experience.

I found this out after buying $300 headphones to drown out a coworker in an
open lab space, and I couldn't wear them for more than 5 minutes at a time.

Dear all,

I have used different noise cancelling on-ear phones for a while such as:

Bose QC 30: Very good on noise from low to high frequencies. Not very
effective in the frequency range of the human voice from 1500 - 3000 Hz.
Comfort on ear for lengthy sessions of wearing is 4 out of 6.

Sennheiser PCX 550: Very good on noise from low to high frequencies.
Less effective in the frequency range of the human voice from 1500 -
3000 Hz than the Bose QC 30. Comfort on ear for lengthy sessions of
wearing is 6 out of 6.

Bowers & Wilkins PX Wireless: Very good on noise from low to high
frequencies. If you use the app with it you can nicely adjust the
opening / closing of the frequency range of the human voice, sort of
like an inverted equalizer. Comfort on ear for lengthy sessions of
wearing is 5 out of 6. They look very posh, that might disencourage some
people from using them in a professionel environment.

All of them cost around 400 €. My favourite at present is the B&W one.

Best Ralf
