Recommendation on IEM or closed circumaural for intermittent noise

post #1 of 4
Thread Starter 

Good morrow everyone,

 

 

My name is Kartik and I am an electronics technologist working in the oil and gas industry here in Alberta Canada. Due to the nature of my work I am exposed to an intermittent and audible sound from one of the pieces of equipment I work on. It is loud enough that I get nauseous from it.

 

I took a screen shot of it using my phone and an app. The frequencies are 6.6 kHz, 7.2kHz and 14.4 kHz. They are audible with duration of less than 0.25 seconds with ~1.5 second intervals. The waveform is a square wave and it hurts to listen to it.

 

 

 

 

The most painful is the 14.4 kHz as it feels like someone is poking a needle in my ear. I have tried to drown it out with music (Note 3 with supplied ear buds) as well as hearing protection but none work as the 6.6 and 7.2 kHz just creep in. Even with background noise its very audible (I just seem to be the only one to be bothered by this noise as everyone here is "used" to it).

 

I was wondering if there were any recommendations based on the info I provided for circumaural closed set of cans or IEMs. Thanks for your help!

The Bose QC15's are the number one headphone with (active) noise cancelling. I'd be damned if you could still hear those sounds while listening to music with these.

So I guess Ill have to give the Bose a try since my work ordered the Asus Vulcan ANC and it does an OK job of ambient noise but did not help with those intermittent noise at the frequencies I outlined in my first post. Also I think IEM may do a better job for me. Too bad there aren't any good shops around Calgary to try out some head phones frown.gif

Sent fabulously from a fabulous phablet in the hands of a fabulously dressed phantom with a fabulous phone...which is a fabulous phablet.

Bose has an active noise cancelling in ear. It's called the Bose QC20. Perhaps that is what you are looking for.
