Abstract
One of most relevant limitations of acoustic guitar (that cannot be electrically amplified) is the low power of its sound, which very often can hardly be heard by the audience. No methods exist for quantitative evaluations of such feature and this make researches in this field particularly difficult, since it's impossible to compare an instrument to another. An effective and reliable method for measurement of acoustic efficiency of guitars and most other stringed instruments is presented, with some experimental result. The measurement approach of the method leads to a repeatability of about 4% in results.
