Noise Attenuation


Recommended Posts

I have an ANR system installed in my Alpha Eagle helmet. Works very well in the S76 with the "noisy" gearbox. However, two small problems. Because there is no volume control on the helmet setting audio levels is a challenge, especially with an aircraft with alot of electronic noise from a variety of systems. The system we have uses batteries. With the high cost of 9 volt batteries plan on getting an aircraft power source, otherwise you will go broke!

 

In our Twinstar the noise reduction is there, but not signifigant enough to justify the expense.

 

We work in a tropical country and the ANR system literally coroded to pieces in a year. I am testing a new "coated" system to see if it will survive.

 

Stay warm!
