Embodiments of a laminate exhibiting enhanced acoustic performance are described. In one or more embodiments, the laminate includes a first substrate, an interlayer structure and a second substrate. One or both the first substrate and the second substrate have a thickness less than about 1.5 mm. In one or more embodiments, the interlayer structure includes a first interlayer and a second interlayer, wherein the first interlayer has a lower shear modulus than the second interlayer and is positioned near the center of the laminate (i.e., positioned at a thickness range from about 0.4t to about 0.6t, where t is the laminate thickness). The laminates exhibit a transmission loss of greater than about 38 dB over a frequency range from about 2500 Hz to about 6000 Hz. Vehicles and architectural panels including the laminates described herein are also provided.
