Airplanes and rock bands in the 70s have destroyed my hearing. I am looking at hearing aids next week. Due to improvements in signal processing over the years I am hopeful that I will find a device that works well for me. Working well for me also means working well for aviation. I normally now use an ANR headset, Lightspeed Zulu 2 at the moment. Any advice on hearing aid selection prior to my appointment next Friday will be appreciated.
