This study presents a generalized photoacoustic model for hydro-semiconductor media incorporating the multi-temperatures theory, aimed at advancing the understanding of coupled optical, thermal, and elastic wave interactions. This approach marks a significant departure from traditional single-temperature frameworks, capturing the inherent complexity of hydro-semiconductor materials subjected to high-intensity photoacoustic phenomena. The governing equations are derived by coupling photo-thermoelastic and hydrothermal effects within the multitemperature paradigm, incorporating boundary conditions relevant to semiconductors. The normal mode analysis technique obtains analytical solutions for main physical fields. Comparative simulations are performed for conventional and multi-temperatures models to evaluate their accuracy and predictive power. Graphical representations illustrate the superior precision of the multi-temperatures theory over classical approaches, especially under conditions of rapid thermal changes. The results highlight the advantages of the multi-temperatures framework in enhancing wave propagation analysis.
