Don't Expect Silence
22 August 2018
These are, at best, mufflers. You can still hear every noise that you could hear before, just with less volume. I bought these to try and help me sleep in a hotel on a busy pedestrian street with buses and cars, a railway line and a rail station. I can still hear people talking normally outside the window, I can still hear all the cars, I can still hear the trains. However, those sounds are not as penetrating as they were before, and being muffled makes them less disturbing.
One side effect is that my tinnitus is much more noticeable with them in. It wakes me up quite often with high pitched whistling, but generally I am not troubled by it too much during the day. With the plugs in, however, it is much more pronounced (and annoying), but that is probably a good sign that the real external noises around me are much quieter. To be clear, the plugs DO NOT make the tinnitus worse, they just can't muffle it like they do with real noise. :-)
Did they help me sleep? A little bit, and enough to justify the small cost.
