iPhone plays random sounds

Every now and then (1 or 2 times a day) my iPhone start playing these random sounds. They sound like adds or tiktok/youtube short videos. ( dont have tiktok). I cant seem to find what causes this. It is definetly not one of my apps since i haven’t installed anything recently. I deleted all my safari tab and cookies, damn i even just reinstalled my phone completely and it still happens. (Even updated to ios 18)

Is anybody else experiencing this or something similar?
