Diffuser/Absorber Panels
Purpose: To provide a mixture of diffusion and absorption, creating a balanced room acoustics. Placement: On walls or ceilings where both effects are desired.
Helmholtz Resonators
Purpose: To target and absorb specific frequencies, often used to treat room modes. Placement: Customized location based on the frequency to be addressed and room analysis.
Bass Traps
Purpose: To absorb low-frequency sounds and reduce room resonance. Placement: Corners of the room where bass frequencies tend to build up.
Diffusers
Purpose: To scatter sound waves and reduce standing waves without removing too much energy from the room. Placement: Back wall or other strategic locations to maintain a lively sound.
Acoustic Panels
Purpose: To reduce reverberation and flutter echoes in mid to high frequencies. Placement: Walls at the reflection points and sometimes the ceiling.
Ceiling Clouds
Purpose: To reduce vertical reflections and flutter echoes between the floor and ceiling. Placement: Suspended from the ceiling, usually above mixing position or performance area.
Acoustic Foam
Purpose: To attenuate mid to high-frequency echoes, reverberation, and reflections. Placement: On walls, ceiling, and other reflective surfaces.
Bass Columns
Purpose: To control low frequencies and reduce modal issues in room corners. Placement: Fixed setup in the corners of a room or spaced out at regular intervals along the wall.
Variable Acoustics Systems
Purpose: To allow a space to be acoustically adaptable to different types of performances or recordings. Placement: Integrated into the architecture of the room, sometimes using movable panels or curtains.
Acoustic Curtains
Purpose: To provide flexible sound absorption and manage reverberation. Placement: Along walls or over windows to also block external noise.
Fabric-Wrapped Panels
Purpose: To provide aesthetic options while improving room acoustics through absorption. Placement: On walls in patterns or specific artistic layouts that complement the interior design.
Skyline Diffusers
Purpose: To scatter high frequency sounds evenly throughout the room. Placement: On the wall behind listening position or mixing station.
Resonant Absorbers
Purpose: To attenuate resonant frequencies more effectively than porous absorbers. Placement: Can be distributed throughout the room or focused on problem areas for specific frequencies.
Poly Cylindrical Diffusers
Purpose: To diffuse sound waves and reduce standing waves while maintaining a live sound environment. Placement: On walls in performance spaces or listening rooms.
Corner Impedance Tube
Purpose: To absorb low-frequency sound waves and minimize room modes. Placement: In room corners where sound pressure levels are naturally higher.
