does secondary glazing work for voice noise close to the outside of a building?

can anyone testify for the effectiveness of secondary glazing (in my case it would go over regular double glazing) for speaking noise close to the outside of the window e.g. from the outside space below a 1st floor window. i only hear people talking about its effectiveness for traffic noise so im curious if theres a difference. thanks!
