The present invention relates to a glass laminate comprising a polymer interlayer formed over a first major surface of a first chemically-strengthened glass sheet and a second strengthened glass sheet separated by the polymer interlayer from the first chemically-strengthened glass sheet. The first chemically-strengthened glass sheet has a thickness less than 1 mm; and a near-surface region under a compressive stress, wherein the compressive stress (CS) at a surface of the first glass sheet is greater than 400 MPa, and wherein the glass laminate has a transmission loss that does not decrease by more than 1 dB over any 100 Hz interval over a frequency range from 250 to 5000 Hz.
