Abstract
A breast pump device () is equipped with or used in conjunction with an acoustic milk expression assessment system () for the purpose of obtaining an indication about a fat content of expressed milk. The acoustic milk expression assessment system () includes an acoustic sensor () and a processor () configured to process an acoustic signal received from the acoustic sensor () during operation of the breast pump device () when a milk receptacle () is used with the device (). By recording sound during a pumping session, it is possible to determine a frequency shift in the sound of droplets falling down in the receptacle () and hitting a surface of the milk contained by the receptacle () with respect to a reference situation of a liquid having 0% fat content, which can be taken as a factor in estimating a value related to the fat content of the milk.
