Hearing is going

[newtech]

My hearing has been degrading for a while now and has gotten to the point that something needs to be done. Today I had two situations that were directly hearing related. The first one wasn't a safety issue; I just had trouble understanding a tower controller that had a higher pitched voice. The second one was a safety issue that has me pretty concerned. Coming into a Class C airport I heard the controller direct me to enter a left downwind for 18. I read back the direction and received confirmation. I proceeded to position for an entry to a left downwind for 18 and the tower instructs an immediate turn. My passenger confirmed that the clearance, from the tower, was for 36 not the 18 that I thought I heard. She didn't say anything because she just thought she had heard it wrong. It was me that heard it wrong.

Now to the reason for the post. Is there a headphone pre amp that can be inserted between an intercom or audio panel and the headphones that includes bass and treble controls? hearing-aids are probably the solution but it would be nice to be able to tailor the audio going the the headphones.

If you have a 28 volt aircraft, the PS Engineering's PM1200 intercom can provide plenty of audio output. The output amplifier in that unit provides up to 200mW into General Aviation Headset.

The other function of the PM1200 is the Active Microphone Processor where the back ground noise is significantly reduced.

I have severe high frequency loss with FAA waiver, and the communications ear protection (CEPs) in my headset that the US Army uses works better than ANR for me. Here's a website link: http://www.anr-headsets.com/Html_folder/CEP.html

I use the CEPs with good results and now have a Halo from Quiet Technologies that I really like. When I am flying my Yak (very loud), I prefer the CEP which is set up to use with my ANR headset. I really like this combination due to the huge noise reduction. In my RV I usually use the Halo.

Thank goodness we can read this.....

I think the problem is the high frequencies need to be amplified while the lower frequencies are kept at "normal" levels. Is there a pre amp that just amplifies the higher frequencies?

I have CIC hearing aids (Completely In Canal) and they work well with my Lightspeed headset. admittedly, the larger external hearing aids might not allow headset use, but the CICs seem reasonably compatible. FYI - my hearing loss is "moderate to severe" above 3500Hz.

Maybe try an equalizer for PA systems. Musicians friend has a selection. Pick a cheap one with 1/4" in/out jacks and put it inline with your headphones. Find a frequency with chatter and start boosting and cutting.

I have behind the ear hearing aids from Costco and they work great in anr headsets. I also needed a boost in the high frequencies but not the low. ATC and the towers are all clear now.
