Animal+Calls

The optimum frequency range for humans is around 2,000 Hz. For dogs it is around 8,000 Hz. The maximum frequency limit for humans is 20,000 Hz and fordogs it's 48,000 Hz. = __Dog Whistle__ = Dog whistles work by forcing air down the length of a cylinder and out of a hole that is split by a sharp edge. The longer the cylinder is the lower the whistle's pitch will be. The shorter the cylinder, the higher the pitch. In order to generate the right pitch and frequency, dog whistles must be very short, around one inch or less.



Duck and Goose Calls Calling is important in a sense that the hunter is creating a realistic situation to live ducks and geese in conjunction with realistic looking decoys. This attracts them to the area around the hunters possibly giving them a chance to get a good shot. Duck and goose calls are made out of three types of materials and they are wood, polycarbonate, and acrylic. Wood was the first material used for calls. This type of material produces a mellow and raspy sound that some hunters consider more natural. There are a few types of wood manufacturers use such as maple, cocobola, and Bois D' Arc, African Blackwood, and Bocote. All these may produce subtle variations of calls and may cost more than others due to their availability.
