Music in restaurants without unnecessary noise

Zazajoj

We are opening a small restaurant on the ground floor of a residential building, and now we are faced with the question of sound. We want the music to create atmosphere, but at the same time not disturb the residents upstairs. I've heard stories of neighbors complaining even about moderate noise, especially in the evening. I really don't want to get into any conflicts, so I'm thinking about which systems would be best to choose so that visitors are comfortable and those upstairs aren't bothered.
