Acoustical Canvases is not a biography: rather, it aims to provide a thorough introduction to the 31 years of Poul Ruders’ comprehensive musical out- put from his debut in 1967 to the completion of the spectacular, full-length opera The Handmaid’s Tale in 1998. Most of the information included in this book is not currently available anywhere else.
Acoustical Canvases deals chronologically with
Ruders’ entire output prior to 1998 and provides
detailed analyses of many significant works. The
focus is on compositional technique and on the stylistic aspects of the music, and descriptions of the works are supported by 83 musical examples and diagrams. The change ringing technique which Ruders developed after 1974 is of key importance. Although this text acknowledges the written contributions of others, the author’s own observations form the basis for the book.
Although the compositional process is the main focus on the author’s attention – what he has to say about the music is primarily of a technical nature – every effort has been made to present the subject as clearly and as simply as possible. Thus this book is designed to be accessible to anyone who’s interested in the music of Poul Ruders.

It is estimated that approximately one-third of households in the U.S. own firearms. 1 There are 28 million Americans who consider themselves hunters, and 13 million went hunting in 2000. 2 Participation in shooting sports without the use of properly worn hearing protection exposes participants to high levels of impulsive noise that may cause hearing loss or tinnitus (ringing in the ear). Firearms may cause permanent hearing loss even after a single or a few unprotected exposures. The present study was initiated to gain a better understanding of the noise exposure created by contemporary firearms using state-of-the-art instrumentation and to ultimately increase our knowledge and awareness of this unique noise hazard. The sound created by recreational firearms used in hunting or target practice is characterized by a high-frequency, short-duration impulsive noise. This signal is perceived by the human ear as one single, loud impulse or "shot." However, when the firearm sound level is measured with microphones capable of sampling wide frequency ranges and combined with high-speed, data acquisition computer systems, the impulses can be resolved into a number of different acoustic signals related to different source mechanisms. The acoustic characteristics of firearm impulse noise put great demands on the instrumentation. Therefore, the transducers and the data acquisition system are critical, especially in terms of dynamic range, frequency response, slew rate and sampling rate, all of which need to be carefully considered. This study focuses primarily on recreational firearms as a noise source and considers the acoustic interaction of the resulting sound field with the human head. It does not delve into the potential auditory damage experienced by an individual shooter or extend to discussions of specific auditory risk criteria.
