Alan Day Posted January 2, 2021 Share Posted January 2, 2021 Be careful of the cheap small hearing aids being sold on FB .Plastic over a period of time age hardens (like brass) and the one I tried disintegrated at the place that holds the battery in position, rendering them useless.

In my experience, the Eargo units can make the sound a little tinny if cranked up, and they also create some annoying minor feedback at seemingly random times for music in general. But other than that, they're rechargeable, work very well, are almost unnoticeable, and are an amazing piece of tech. Since we play a Victorian instrument, maybe we should just get a pair of nice brass ear trumpets mounted on some sort of hands-free headset - it would fit in better with the whole Steampunk theme. Or perhaps an industrial size unit like the photo? Gary This is hilarious. What's this from? Was he trying to contact space aliens or something?

It was used during wartime, pre-radar, to listen for the distant sound of enemy aircraft. The listener would rotate it to find the loudest direction, then read the bearing to find the direction of the sound. Two or more bearings from different listening stations could be plotted on a map to triangulate the position. 1 Quote Link to comment Share on other sites More sharing options...
