Room Acoustic Visualizer

Interactive tool for room modes, Schroeder frequency and acoustic behavior

Important: This tool assumes a rectangular room and a standard setup where the loudspeakers are placed on the short wall, firing down the length of the room. Results may be inaccurate for irregular room shapes or unconventional speaker placement.


Typical RT60 values:
• Treated small studio: 0.2–0.4 s
• Living room / bedroom: 0.4–0.7 s
• Untreated large room: 0.7–1.2 s
Lower values = tighter, more controlled bass.
Legend:
Axial modes – strongest room resonances
Tangential modes – medium impact
Oblique modes – weakest modes
Schroeder frequency – transition from modal to diffuse field

Mode Density

How to read this graph:
• Horizontal axis: frequency (20–300 Hz)
• Vertical bars: how many room modes exist in each band
• Taller bars = higher modal density = smoother bass perception

Where Bass Builds Up and Disappears in Your Room

Move the slider to choose a bass frequency. The blue curve shows where this frequency becomes louder (peaks) or almost disappears (nulls) along your room length. The green line marks your listening position.

2D Pressure Map (Room Top View)

Listening position explorer (top view): Front wall with speakers is on the left side of the map. Click on a raw of the table and then click on the map to evaluate potential listening positions.
This map shows how sound pressure distributes across the room for the selected mode. Bright areas = pressure build-up (antinodes). Dark areas = cancellations (nodes).
Tip: Click on a frequency to see how that room mode builds up and cancels across the room.
