Abstract: An apparatus for generating an acoustic profile representing the acceleration pattern of an object moving through a path of travel. The apparatus comprises a flute assembly attachable to a golf club. Preferably, the flute assembly comprises three cross flutes with three different fundamental frequencies aligned axially on the shaft of the club. The swinging motion of the club creates a complex, multi-tone acoustic profile indicative of the acceleration pattern of the club throughout the down swing. The golfer can then compare his profile to the swing of a known, great golfer, and then practice until he duplicates the sound of the model swing. While the apparatus is especially useful for golfers, the apparatus may be adapted to a wide variety of other sports implements, such as baseball bats, hockey sticks and tennis rackets, for example. An assembly comprising the apparatus in combination with the sports implement is also provided.

Abstract: A sound receiver outputs a signal to a sound level detector and to a notification signal generator. The sound level detector outputs a signal to a first input of a switch, and the notification signal generator outputs a signal to a second input of the switch. Also input into the switch is the program from a program source. Under control of the sound level detector, the switch either outputs the program or the notification signal to an output element of the alarm system whereby the program is interrupted and the notification signal substituted therefor on detection of a sound level greater than a preselected level.
