Hi Lidia- sounds like you 've done a lot of probing over your own Hum. You would make a good test subject, I think. pity the Gov't is not likely to do such work. [realistically] I've suffered tinnitus for ages- quite bad now - but mostly due to meds for high BP- it increases liearly with dosages of some types. We had a poster very keen on tinnitus being hum based and never could shift him. I'm quite happy to see them as co-incidental, as you find it - but I think they are separate entities as to their causes.
