Phonocardiography is a useful technique for demonstrating the characteristics of murmurs. It is also applied in conjunction with other techniques such as echo-cardiography and pressure measurement to identify the timing of events during the cardiac cycle. The technique has many applications in an academic situation:

however, it is seldom useful in clinical practice. The principal limitations are that it is difficult to obtain quality, artefact-free recordings and that equipment suitable for use in the horse is quite expensive. Good quality phonocardiography transare often bulky and are difficult to position in the axilla where the PMI of some murmurs is located.
