Horn - one sided sound?

[wdrx02]

Hello,

I got my car back from the shop not long ago and I want to confirm for our cars.
When you honk - it is suppose to be on both side or just one side?
I just don't recall its only one sided, which; makes it sound low.

Are horns suppose to be on both side or NOT to - sound one sided? i.g passenger side?

Should be two - looks to be one on each side (hi-lo)
