Simple RT60 Calculator for Home Theaters and RoomsUnderstanding and controlling reverberation is one of the most important steps in creating a great-sounding home theater or listening room. This article explains what RT60 is, why it matters, how a simple RT60 calculator works, how to measure and estimate RT60 for different rooms, and practical steps you can take to improve acoustics using the calculator’s results.
What is RT60?
RT60 (reverberation time) is the time it takes for sound to decay by 60 decibels after the sound source stops. RT60 is expressed in seconds and varies by frequency. In simple terms, RT60 tells you how “live” (long decay) or “dead” (short decay) a room sounds.
Why it matters:
- Too long RT60 → muddled dialogue, unclear bass, lack of detail.
- Too short RT60 → overly
