    Sound Baffles Industrial Noise Solutions | eNoise Control

    Sound baffles are a low cost and non-intrusive solution to many common noise control problems. These ceiling or overhead baffles absorb reflected noise (sometimes called reverberated sound) bouncing off hard flat walls, floors, or ceilings. This often manifests as an echo and can make it difficult to hear conversations in these types of spaces.
