Acoustic Threshold

Acoustic door thresholds, commonly called saddle thresholds, are used to help reinforce soundproof door assemblies to reduce air gaps beneath the door. Acoustic door thresholds, also known as sound-rated thresholds are normally used in conjunction with automatic door bottoms and acoustic door seals to create a complete soundproof door assembly for best results.   These engineered thresholds are designed to aid with a door's STC rating.
