Claim:
1. A low-profile hearing assistance spout device for a hearing assistance device including a microphone having a planar acoustic microphone port, the spout device comprising: a planar portion, the planar portion configured to mount adjacent the microphone with a planar surface forming an opening in alignment with the planar acoustic microphone port of the hearing assistance device; and a cylindrical spout portion connected to the planar portion, the cylindrical spout portion including an aperture that defines a curved path for sound, the aperture offset from the planar portion surface so that the planar portion surface is approximately coplanar with the center of the aperture, the cylindrical spout curved path in acoustic communication with the planar acoustic microphone port to provide an acoustic pathway for sound received by the cylindrical spout portion to reach the microphone, the cylindrical spout curved path forming a spout connection to the planar portion at an angle that is not perpendicular, the aperture offset and spout connection to reduce ingress of unwanted materials that may reach the microphone.
