If you listen to the tinnitus sound(s) the brain will take into consideration your wish to hear the tinnitus and will filter out other sounds and pump up the volume of the tinnitus, for you to hear better what you are interested in.
This happens to all types of sounds, not only tinnitus.
If i am very interested in the sound of the refrigerator, of the car engine, i will hear in a short time almost only the sound of the refrigerator or the car engine, even if before i was not hearing them, because i was oblivious to them, i was considering them unimportant.
The brain can select the sounds it is interested in, and make them the main sound we hear, and put in the background all the other sounds.
We hear what a person says in a very noisy environment, the moment we are interested in what he is saying. We filter out what what other people are saying at the same time. The moment we lose interest in what a person says, the other voices come back from the background to our attention. If we want to hear what another person is saying, the voice of that person is brought in the center of our hearing.
To hear something that is not very loud and represents no danger to us, we have to think of it as very important, in order to hear it.
In a noisy environment, if i think i hear a knock at the door, i will be able in the following moments to not be bothered by the other sounds and hear clearly whether somebody is knocking at the door or not, and if someone does, i will hear very clearly that knock, cause i gave it priority nr 1. on the list of all the sounds that can be heard.
We do not want to do that with tinnitus, so my advice would be to NOT listen to the tinnitus.
The only sense that would make listening to the tinnitus for a while would be to see for ourselves that hearing it does not bring death, and close this chapter, but we must switch focus on external sounds after that, cause otherwise tinnitus will be the main sound we hear, front and center.
I am not talking, of course, about spikes. Spikes have a talent to take the center spot in our attention, because, unconsciously, the limbic system, the amygdala, gave them rank nr. 1. We are afraid that the spike will last for a long time, if not for the rest of our lives, and the moment we do that, it takes center stage in our attention.
I would advice, when having a spike, to turn on the radio at low volume. In many cases, not all, but in many cases, you will see that the spike gets lower in volume, which proves that, in order to hear something, two conditions must be met:
1. That sound (external or internal) to be audible
2. To "listen" to it. When we listen to the radio, we do not listen to the tinnitus, and you will see that you will hear, mainly, the radio.
A tinnitu of, say, 50 db, can sometimes, be covered by a sound of 30 db or less, just because the focus of the brain switched to the 30 dB sound. The volume of a spike cannot be measured because "measuring" means "comparing" it with a measuring unit, and the moment we bring another sound into the mix, which is one or several times the measuring unit, the tinnitus sound gets lower, taking a back seat.
There are sad times, unfortunately, when the sound of tinnitus does not subside when we listen to other sounds. That is why some people killed themselves, because the sound would simply not go down.
It happend to me to have both types of spikes, maskable, and not maskable.
Good luck to all of us!
