Abstract of the Disclosure The invention describes a method and an apparatus for the acoustic counting of individual particles, more particularly particles of seed material to be sown whereby, by comparison of the vibratory signals actually received as a result of grains impinging upon a sound transducer having pre- determined characteristic vibratory signals, it is determined whether a signal pattern typical of one grain or of another grain is present. Individual particles are thus counted and this permits relatively accurate detection thereof. The apparatus for the implementation of the method consists essentially of an evaluating circuit in which characteristic signal curves are stored, with which the signal curves actually detected are compared. The number of particles actually impinging are also determined from this comparison.
