Abstract
A sound comparison device for a drum that has a body that includes a bottom with a periphery. The periphery of the bottom of the body is in contact with the surface of a drum head. A drum head tension measurement element includes a tip which protrudes from the bottom of the body. A spring biases the tip to press against and sink into the drum head to a distance determined by the tension on the drum head. A display is connected with the measurement element for causing the display to display a numerical value Y which corresponds to distance X of the protrusion of the measurement element. The values X and Y are coordinated so that the display displays the value Y=K/X1/2, where K is a constant.
