Re: [AUDITORY] Noise cancellation earbuds

[Matt Flax <flatmax@xxxxxxxxxxx>]

Nice high tech approach!

On the plane, I use a pretty low tech approach. I like to wear standard phone ear buds with hearing protection style muffs on top. The hearing protection muffs give around 30 dB protection across most of the spectrum. At the hardware store, the muffs typically give attenuation ratings vs frequency in their specifications on the packet. If you get a version with deep shells, then the ear buds don't even touch the sides.

It may look a little excessive in an office environment !

Hi,

 

Not science but I have been using the HF-5 (and pre-cursor) for airplane travel for the last 15 years and I love them. I also have the much more expensive Bose NC headphones but I find the Etymotics are much better for listening to a movie on the plane.

I use the foam tips mostly.

 

(as the in-ears are most effective in higher frequency but the active noise cancellation is more effect in the lows, putting the Bose OVER the HF-5s is amazingly quiet J)

We evaluated the attenuation provided by Etymotic HF5 noise-isolating earphone (cost < $150) in a sound-attenuating chamber using three different ear tips provided by the manufacturer.  We measured speech recognition thresholds (SRTs) using spondee words in the sound field with both ears of the subject plugged by the ear tips. Four participants were evaluated.  The eartips evaluated were the Etymotic Research ER38-15SM 3-Flange Ear tips (size small), ER38-18 Large 3-Flange Ear tips, and the ER38-14F Standard Black Foam Ear tips.   The foam ear tips provided the most attenuation, which is approximately 20 dB. 

 

Hope this is helpful.

Hi, my sister is very easily distracted by noise, esp. in the office where she works, and she wants some suggestions for good noise cancellation earphones. She'd like to spend less $150, and is willing to get used ones. So if any of you know of some good models, and places to get them for under that amount, please let me know!

Thanks in advance,

Brian Gygi
