Bandoneon! (a combine), performed in October 1966 as part of the 9 Evenings: Theatre and Engineering, has been regarded as Tudor’s first work as a composer. However, the conception of this piece was not only directly influenced by two other amplified bandoneon pieces he realized in the same year, Gordon Mumma’s Mesa and Lowell Cross’s Musica Instrumentalis, but had also started off as a realization of a “Mobius-Strip” composition by Mauricio Kagel. Moreover, most of the modular electronics in his setup were also used in other realizations around the same period. The true difference lies in how these common materials were used and to what ends. What the self-proclaimed effort to make a “giant white noise generator” from scratch brings to the fore is a synecdochical relationship between the modular instruments used and the larger instrumental complex they compose. The investigation of this coordination between the parts and the whole reveals a strange disappearance of an entire group of instruments considered central to the performance, a mystery that highlights the peculiar nature of Tudor’s “composition.”

AbstractTinnitus retraining therapy has been heralded as a major advance in the alleviation of tinnitus perception. A cornerstone of this technique is to use white noise produced by a white noise generator (WNG) over a period of several months in order to assist the patient to habituate to their tinnitus. There are three factors which influence the frequency spectrum of the perceived noise such that the perception of white noise from a WNG is unlikely. These factors are the actual spectrum of the emitted noise, the ear canal resonance of the patient and the hearing sensitivity of the patient.Advocates of tinnitus retraining therapy state that white noise is the optimal stimulation to assist habituation of tinnitus. This paper demonstrates that this optimal situation is unlikely to be achieved and that this may account for the long periods needed for patients to achieve benefit from the technique. The development of devices that allow for the above factors to be countered is suggested.

White noise generators can use uniform random sequences as a basis. However, such a technology may lead to deficient results if the original sequences have insufficient uniformity or omissions of random variables. This article offers a new approach for creating a phase signal generator with an improved matrix of autocorrelation coefficients. As a result, the generated signals of the white noise process have absolutely uniform intensities at the eigen Fourier frequencies. The simulation results confirm that the received signals have an adequate approximation of uniform white noise.
