Written for voice professionals, their teachers and those who care for their voices, this unique book covers voice acoustics, the effect of the acoustics of spaces on the voice, and how to make a voice recording properly. The book is wholly practical and written in a manner which is rooted in science but which is designed to enable understanding by non-scientists and voice practitioners alike. The authors provide an outline of acoustics and the human voice, before going on to cover ways in which voice users - from professional and amateur singers and performers, through lawyers, to school teachers - the largest group reporting to clinics with vocal problems - can improve vocal efficiency, regardless of location, and vocal health. Also covered are methods of amplification, whether through microphones, or simply by posture or stance and best methods for sound recording.
