Yes, absolutely, but it'd be good to make this measurement easy
to repeat by anybody interested.  To do that, let's just loop the
audio output back into the audio input.  The user will have to
provide a loopback cable (or, worst case, put his mike right up
to the speaker, and allow for a tiny bit of extra latency
from that).
