MBP 2014 beeps and ticks randomly

Hi, it started a week ago, this bees comes not from speakers, in the video it sounds loud, but its very quiet, i was walking around the room for an hour trying to figure out where this quiet beeps coming from, because i could hear them when its totally quiet only.

i tried to search for similar problem, but usually everyone has more loud proper system beeps, but this one is smh different

also, my macbook works as usual, nothing changed in general, this beeps is really random, they might go 10 in a raw with 5-10 secs interval and stops for a minute or 2 and than comes again.

Ticks every 5-6 secs all the time.
