Design and Modeling of High-Strength, High-Transmission Auto Glass with High Sound Transmission Loss
Development of high-strength, scratch-resistant and highly transparent glass with good sound isolation properties is necessary for automotive, industrial and architectural applications. While major progress has been achieved in developing the mechanical strength, scratch resistance and elasticity of highly transparent glass compositions, achieving broadband sound isolation in glass has remained a challenge due to the intrinsic thicknesses and the phonon band structure of the glass layers used. Since phonon band structure of high-strength glass limits the tunability of its acoustic transmission spectrum, composite multilayer glass designs need to be used to enhance sound transmission loss while maintaining the mechanical and optical merits. In this chapter, the design of high-strength, highly transparent and sound isolating glass is posed as a composite acoustic (meta)material design and optimization problem. Sound transmission loss within human audible range, particularly within 1–10 kHz, must be maximized toward 30 dB or more for good sound isolation while maintaining good optical and mechanical properties over large areas. Next, constitutive and wave equation relations for acoustic modeling of sound transmission loss are presented with example results for polymer/glass sandwich layers. Finally, future research opportunities on new glass materials with tunable phononic band structures, new metamaterial topologies and modeling methods are discussed.
