Musical measurement stimuli

Tue, 16 Jun 2015 08:00:00 EDT

Systems and method for performing adaptive audio signal processing using music as a measurement stimulus signal. A musical stimuli generator may be used to generate musical stimulus signals composed to provide a stimulus with a spectrum that is substantially dense, and ideally white or pink, over a selected frequency range, so that all frequencies of interest are stimulated. The musical stimuli generator may generate melodically pleasing musical stimulus signals using music clips that include any of: a chromatic sequence, a chromatic sequence including chromatic tones over a plurality of octaves, a chromatic sequence including chromatic tones over a selected plurality of octaves, or an algorithmically composed chromatic sequence, to cover a selected frequency range. The musical stimulus signal may be generated as sound into the environment of use.

A tom-tom supporting device includes a bracket, a first arm having a plurality of first supporting portions for supporting an upper hoop, and a second arm having a second supporting portion for supporting a lower hoop. Two of the first supporting portions provided at ends of the first arm are each located near one of two intersection points at which a diameter of a batter head, which is perpendicular to a vertical plane containing an axis of a shell and an axis of the second arm, intersects the upper hoop.



Tabla drum head tensioning system and method

Tue, 05 May 2015 08:00:00 EDT

A system and method for quickly and efficiently installing a drum head on a tabla and controlling the tension of individual segments simultaneously. A mechanical interface controls a tension on each of a set of connective elements of a connective assembly that joins the drum head to the mechanical interface. Operation of the mechanical interface adjusts the tension of all elements of the connective assembly, and thus adjusts a playing tension of the drum head, at the same time.
