Last Saturday we went to the theater to see a play that was really good.

The actors were flawless, but I don't want to talk about thise play but instead about the sound in the plays.

For a reason I docan't knowunderstand, alls plays have some moments thatin which the sound is very, very, very high/loud.

Imagine thant during a play the actors are talking with a normal soundvoices, and suddenly it comethere is a scene with a deafening sound.

For me are, these are a very unpleasing moments that does not make sense.

This ussually occurs in the most of the theater plays in Barcelona, but also in the cinema, popular parties and so on.

I would use extraordinarily high or extremely high. It's not proper use to repeat a word so much
