The traditional way of doing that is by measuring outdoors in a field. 
You still get a reflection from the ground even if there are no trees or
fences nearby, so you either try to minimize that by placing the
microphone very close to the ground, or place both speaker and microphone
on a stand a meter or two tall so that the ground reflection is attenuated
a little.
