I've recently acquired some new Bluetooth "earpods", the type that fit in your ear and are individual with no connecting cable. They're not " noise cancelling " ( I was considering those, but apart from the additional cost I don't like to feel completely isolated from my environment ) They do however cut out a great deal of the surrounding noise simply by virtue of the close fitting silicone ear tips. I know that my hearing is not very good, and I appear to have inherited my dad's poor hearing in his right ear. The earbuds have an App that you can use to analyse your hearing and it takes the results to tailor the sound output to your hearing profile. Using the App consists of sitting in a quiet place and then going through a series of tests where you press an on screen button when you can hear a tone, and release it when you can no longer hear it. It plays tones of different frequencies and you test each ear individually. Intrigued by this I then downloaded and installed a hearing test App and took a hearing test. That seemed a bit more sophisticated and the resulting audiogram confirms what i already knew, that the hearing in my right ear is much weaker than my left. The App also advises that as I used uncalibrated headphones, the results might not be accurate. I do however feel that it is a useful pointer and quite an interesting exercise.
