The present subject matter relates to a capacity detector, a waveguide and a manifold for use with a coin sensor as well as methods for sensing a capacity of a coin receptacle. In one aspect, the waveguide for use with a coin sensor comprises an excitation end for receiving an acoustic signal, a horn end for disposition adjacent to a coin receptacle, and a conduit interconnecting the horn end and the excitation end. In embodiments, the horn end of the waveguide may define a horn selected from a tapered horn, an exponential horn, a tractrix horn, or a modified tractrix horn.
