Maybe 7-10 days, can be longer.
I'm mostly habituated to my tinnitus so I don't pay attention to it during the day and it's mostly mildish anyway so not audible unless I am in a quiet room or stop what I'm doing and listen for it. It is definitely louder at night and reasonably mild in the morning.
During my period though, it can be annoying enough to make me mask at night and mask while watching TV as I still haven't been able to break the habit of measuring whether I can hear it over the TV or not....!!!!
I'm not on birth control pills though, but perhaps it's worth researching whether people report that their tinnitus is worse on birth control pills.
I've decided that I won't go on the pill again (and after three IVF babies I most likely don't need to), and the reason is that I am concerned that it might mess with my tinnitus. I'm OK with it as it stands, and as I strongly believe there is some element of a hormonal link to my tinnitus - both by my cycle and the fact that it came on 1 month after the birth of my twins - I don't want to mess with those hormones anymore!
This may not be the case for you though, as everyone is obviously different. If you search this forum though, you will see a lot of women say that the intensity of their tinnitus varies with their cycle.
As for my sound, it's a head noise (not in my ears).... at it's worst, it's a high pitch hiss, heard mostly in the left side of my head..... I absolutely cannot be in a quiet room as it feels like it takes over my whole head.... makes me shudder to think about it! Usually the hiss is quieter, or not really there and I hear a lower tone in my left ear and my right ear.... I suspect I've had these for a long time and never really noticed them as they are so soft and very tolerable.
I'm happy to hear these as it means the hiss is behaving! It's more the pitch of the hiss I can't stand and not so much the volume.
