If lacking a anechoic chamber, substitute it with: 1 - A large field covered with about half a meter of newfallen snow. 2 - On the top ridge of a gabled barn standing in a field. 3 - In the top of a large free standing tree. Some effort and dedication is needed to replace the cash expenditure

Interestingly, he dinosaur size geese (John Leonard's recording when geese go bad) was played in a field, speaker radius 15-20 metres. And the passing motorbike was impressively large, too. AS a rule of thumb, I've always found that one needs to bear in mind the speaker array radius when
