Mysterious sound / Tajemný zvuk - #7

Shall we give a competition?

Ok lets go. It's easy. Guess both sounds in the video demo. And as accurately as possible. The reward is 1.5 HBD to the first correct bettor. Today with a little help, because the sound was not guessed in the previous round. ** Both sounds have something in common and can be said to be related. ** You can guess once a day to the user. If only one sound is guessed, the answer will be marked as wrong. If the sound is not guessed during the payment period, the sound will be included in the next round with a higher reward.
