Acoustic Performance:

When used in conjunction with solid core wood or metal doors, HUSH SEAL™ perimeter acoustical seals and drop thresholds will greatly reduce noise leakage. Reductions of 5 to 10 dB have been measured in the field. Test results from a leading independent acoustical testing laboratory on operable doors fitted with series 100 and 200 seals showed STC ratings of 44 to 46.
