Active noise control - the reduction of noise by generating an acoustic signal that actively interferes with the noise - has become an active area of basic research and engineering applications. The aim of this book is to present all of the basic knowledge one needs for assessing how useful active noise control will be for a given problem and then to provide some guidance for designing, setting up, and tuning an active noise-control system. Written for students who have no prior knowledge of acoustics, signal processing, or noise control but who do have a reasonable grasp of basic physics and mathematics, the book is short and descriptive. It leaves for more advanced texts or research monographs all mathematical details and proofs concerning vibrations, signal processing and the like. The book can thus be used in independent study, in a classroom with laboratories, or in conjunction with a kit for experiment or demonstration. Topics covered include: basic acoustics; human perception and sound; sound intensity and related concepts; fundamentals of passive noise-control strategies; basics of digital systems; basics of adaptive controllers; and active noise control systems.

These poems came to me individually and spontaneously in the sequential order as dated. Some came to me as fast as I could write them down. Inspiration for them came from a variety of experiential directions and musings, and it felt good to write them. I hope that readers find inspiration in them for their own personal journeys. Sharing my efforts in cultivation of higher vibration thoughts and feelings for the benefit of others is a challenge and a privilege.

Cascading Catalyst is a sequential continuation of my inner process begun with my previous book, Percolated Couplets.These entries are each dated and presented in chronological order, as in the first book. Again, they are intended to both invite and reveal and to inspire.
