Acoustics for Glass and Laminates

Terrence A. Dear

Glazing chosen for window vision panels can
affect interior noise quality. Both empirical and
theoretical differences exist between monolithic
and laminated glasses and multiple-pane glazing
units which affect performance. Test guidelines
for measuring third-octave band transmission
loss and classifying acoustic properties of glazing
units without frames are being developed. Single-value
parameters, such as STC and Rw, can be
useful for ranking materials. However, an
improved approach to full octave band
representation is possible, which can have
significant advantages for product design and
applications.
