Sound Transmission Class (STC) ratings for glass indicate how well a partition, wall, or window mitigates or blocks sound and reduces noise.
The STC Ratings for double paned windows usually vary from 26 to 33. Most have good air seals, but the variation is due to the glass thickness and the amount of air space between the glass. The bigger air space and thicker glass is preferred. Soundproof Windows range from 48 to 54 (wit...

for this variability. However, inter-experimental variability is most likely a direct result of the heterogenous non-stable nature of the cell line. Cultured STC-1 cells demonstrate 95 % immunoreactivity to CCK, while only 7 % stain positively for GIP (Rindi et al.1990). Glassmeieret al. ...
