A word often used in tinnitus forums these days is: "Reactive" tinnitus. people affected will say something like: "
I have habituated but my tinnitus is reactive to certain sounds" or
" I have reactive tinnitus". I believe there is some confusion here and will explain.
Someone that has tinnitus especially when caused by loud noise exposure hyperacusis (sensitivity to certain sounds) is often present. If hyperacusis isn't treated the auditory system will always be sensitive to certain sounds even after habituation has been reached. It is for this reason the use of white noise generators (wngs) is recommended to help desensitize the auditory system. White noise generators are used as part of TRT (tinnitus retraining therapy) and must be adjusted correctly as not to irritate the inner ear (cochlear) when wearing them. This treatment is best done under the care of a Hearing Therapist.
When a person says they have "reactive tinnitus", in my opinion, they are not aware they have hyperacusis, which is causing their tinnitus to spike when they hear certain sounds. Although hyperacusis can improve by itself with time, without treatment there is no guarantee. For this reason I often recommend a person to use sound enrichment (sound therapy) as it helps to desensitize the auditory system.
Inside the human body is noisy place but our brain has learned to filter out much of this sound so it doesn't focus on it. Anyone with tinnitus that sleeps in a quiet room risks making their tinnitus more intrusive as the brain and auditory system never switch off. If the brain hears silence while we sleep, it has the ability to increase its background activity and at the same time increasing the tinnitus making it louder and more intrusive. A person might not notice this immediately as it's usually a gradual process
When we are in deep sleep a sound machine supplies the brain and auditory system with sound enrichment. Over time, the tinnitus is pushed further into the background making it less intrusive and will help make the path to habituation easier. It is usually best to have the sound machine playing in the background at a low level (slightly below the tinnitus) without drawing attention to itself unlike a radio. For this reason music is not the best source to use at night as it draws attention to itself.
