 I find it absolutely fascinating that we were able to find here today two people who are defined as deaf. I understand that you both define yourself as deaf and yet you have two very different stories or experiences with being deaf. Bartosz you said that with some members of your family you communicate using Polish as a sound language. Could we maybe try to explain that for some of our viewers who might not be familiar with this? So does this mean that you do have some level of hearing thanks to the implant? Could you perhaps briefly tell us how this implant as a device works and what role it has in your life? SKT was something you could not hear at all. My mother rehabilitated me, she taught me to listen to sounds and oral methods. Just reading from the mouth, because these sounds did not come to me, really. And the difference between the devices and the implant is that the devices used my hearing aids, and the implant goes down the path straight to this slipper, from this slipper. So here it connects directly to technology, not my hearing aids. Because the devices did not help me very much. And when I communicated with someone, I focused only on thanks to my vision, on what I see and how I read from the mouth. And thanks to the fact that I have this implant, then I hear more. And I was really surprised at the beginning that these sounds are really more. The problem is that I did not understand these sounds then, I did not know them. I did not know what it was because I did not hear it before. So in the age of 21, when I got the implant, I contacted my mother and asked what it was, what it was for sounds. And she said, for example, that there in the room next to her is a shower, the water flows. It was really a big difference. But is it such a wonderful thing that this implant acts as if some miracle? Not necessarily. Earlier it was such a calm and quiet for me, but later it was a very powerful purification of these sounds. And it is very difficult to get used to this implant. It takes a lot of time to get used to it. At the beginning it was only a few hours a day, maximum eight hours. And I had to take off. Now after eight hours of work, I take off the implant. And only when I need it, I put it on. I talk to someone, for example, for an hour, I take it off and put it off. Because I really don't need an implant every day in my life. I treat implants as my support. And not as treatment, not as tools like glasses, that when I need it, then I use it, I don't need it, I take it off. So when it comes to the difference between apparatus and implants, it is a technical difference. But the second thing is that in order to hear it, you really don't have to learn these sounds. During the coronavirus, when we stopped going to work, everything was closed, the work was given at home by the camera, I had a problem that I couldn't talk online through the camera. Because I heard the sounds, but they were different, and I didn't fully understand them. Only later, slowly, again, it was an exercise, I also had an application on the phone, which also displayed the inscriptions. I bought the best headphones to be able to follow this sound. I also used the pliers. And thanks to this exercise, I was able to develop in this field, but this is not my completely 100% communication.
