Frequently Asked Questions
What is RT60?
RT60 is the time it takes for a sound in a room to decay by 60 dB after the source stops. A shorter RT60 means a dead, dry room. A longer RT60 means more natural reverb. Studios typically target RT60 between 0.3–0.5 seconds for mixing rooms.
How do I reduce RT60 in my home studio?
Add absorption with acoustic panels, bass traps in corners, and diffusers on the back wall. Soft furnishings — carpets, couches, curtains — also reduce RT60. Bass frequencies are harder to treat and require thick, dense panels or corner traps.
What RT60 is ideal for recording vocals?
For clean vocal recordings, aim for RT60 below 0.3 seconds. Shorter is better when you want to add reverb artificially in the mix. Dead booths can sound too dry for comfort, so 0.2–0.3 s with some diffusion is a practical sweet spot.
