Most acoustically quiet strings?

[Tristan]

I am going to stash a beater bass in my cubicle for lunchtime practice noodling.

What strings would be the stealthiest? Tapewound?

Also, would a fretless be quieter?

Thanks
Tristan

Yup, not really.

Flatwounds are the quietest strings, acoustically. You better be using a headphone amp of some kind because they are very hard to hear acoustically unless the room is very quiet. Fretless would probably be a little quieter because there is no chance of fret rattle.

Yes, I should have mentioned I will get a headphone amp or PC interface to headphones, so I will not need unplugged volume.

tapewounds are electrically quiet, but not acoustically, because under the tape they are roundwounds.
flats are way more quiet.
