Abstract
Method of counting particles of seed, fertilizer, and other materials employed in agriculture acoustically. The particles to be counted are conveyed against an impact plate in such a way as to start it oscillating, generating electric signals that are processed to determine the number of particles. In order to count the exact number of individual particles passing a test point with relatively high precision and by acoustical means, at least one definite oscillation amplitude that is characteristic of the impact of one particle is determined and stored and a comparable actual oscillation amplitude is determined as the particles strike against the impact plate, is compared with the stored oscillation amplitude, and, if it is shorter than the characteristic amplitude, one particle counted, or, if it is higher than the characteristic amplitude, the inference made that another particle has struck the plate.
