โ Frequently Asked Questions
What is RT60 reverberation time, and why does it matter for streaming?
RT60 is the time (in seconds) it takes for sound to decay by 60 decibels after the sound source stops. In an untreated room with hard bare walls, RT60 often exceeds 0.7 to 1.2 seconds, making your microphone sound hollow, boxy, and like you are speaking from a tiled bathroom.
What is the ideal RT60 decay time for gaming, streaming, and podcasting?
The broadcast industry standard for small-to-medium home studio rooms is an RT60 between 0.20 and 0.35 seconds. This provides crisp, upfront vocal clarity without sounding unnaturally lifeless or muffled.
Do cheap 1-inch foam squares actually fix room echo?
1-inch thin polyurethane foam wedges only absorb high frequencies (above 2,000 Hz). While they help eliminate high-pitched flutter echoes (hand claps), they do not absorb boxy room modes in the low-mids (250 Hzโ500 Hz). Thick 2-inch to 4-inch fiberglass or rockwool panels and corner bass traps are far more effective.
What is the Sabine Formula used in this acoustic calculator?
The Sabine equation is RT60 = 0.161 * (V / A), where V is total room volume in cubic meters, and A is the total metric absorption area (sum of each surface area multiplied by its material absorption coefficient alpha).
