1. Acoustic Panels: These panels are designed to absorb sound waves and reduce echo in the room. They can be installed on walls, ceilings, and even furniture.
2. Sound Diffusers: These devices scatter sound waves in multiple directions, reducing echo and improving speech and music clarity.
3. Sound Masking Systems: These systems emit a low-level sound that helps to cover up background noise and improve speech intelligibility.
4. Active Noise Control Systems: These systems use microphones to detect and cancel out unwanted noise, such as echoes.
5. Room Treatment: This involves modifying the physical space to improve acoustics, such as adding or removing walls, changing the shape of the room, or adding sound-absorbing materials.

Implementing one or more of these technologies can greatly improve the acoustics of worship facilities and help ensure that the message is always heard clearly.
