Totally possible. I have the Ego blower and it is much much quieter than any gas blower I ever had. Even better, I'm not worried about the fumes I'm breathing in from it. I'd still hesitate to say they are quiet, though.

To your point, with gas blowers, I know when one is in use in the street. With the electric, I tend to know if in the yard. So, huge improvement. I'd expect if you really hate the sound and are in an apartment complex, you will still hear them some.
