Monograph:

The impressive evolution of automotive audio systems is associated not only with advancements in hardware but also with the emergence of refined scientific approaches to designing and tuning sound within the limited space of a vehicle cabin. The complex acoustic environment of an automobile—with its heterogeneous surfaces, resonances, and reflections—compels researchers and engineers to continually seek methods for optimizing and enhancing sound quality. This situation necessitates not only the proper selection of speakers and amplifiers but also the development of an integrated concept of sound creation, in which every stage—from the mathematical modeling of sound wave propagation to the final listening experience—is imbued with a scientific dimension rather than merely a practical one. A systematic analysis of the issue reveals the emergence of a unique interdisciplinary field that combines electroacoustic principles, psychoacoustic effects, engineering calculations, and aspects of digital signal processing. Consequently, a new type of automotive audio is being established, one whose objective is not solely to achieve high volume or powerful bass but to create an in-cabin audio stage capable of delivering musical imagery with exceptional precision and depth. The present work aims to systematize modern approaches to addressing this complex set of challenges. The integration of a fundamental understanding of in-cabin processes with the technological and theoretical tools required for precise control of tonal balance, filtering, and time correction represents the key to achieving a new level of performance. The monograph reflects the most current methodologies and experiments, culminating in the development of specialized tuning algorithms that encompass every link in the audio chain.
