I haven't posted on here for a while. My tinnitus has been up and down but other health problems have kept me distracted. I've now got a new low frequency sound and I'm really struggling, I can't find anything to mask it and it's waking me up. I'm feeling depressed anyway because of my health and this is making me feel worse. Just posting for support really. Does anyone know of any good masking sounds or websites for low frequency sounds?
