RT60

RT60 is a measure used in acoustics to describe how long it takes for sound to fade away by 60 decibels after the source stops. Essentially, it indicates how “live” or “dead” a space feels; a shorter RT60 means sound is absorbed quickly, creating a dry environment, while a longer RT60 means sound lingers, resulting in a more echoing space. This measurement helps acousticians design rooms for specific purposes, like creating clear speech in a conference room or adding reverberation in a concert hall for richer sound.
