RT60 Reverberation Time
Reverberation Time (RT60) is a crucial acoustic parameter for rooms, representing the time it takes for sound energy to decrease by 60 dB after the sound source stops . It’s used to assess and optimize room acoustics for various purposes. What is RT60 Reverberation Time? RT60 reverberation time is the main room acoustic parameter. Following ISO 3382, it is the duration required for the sound energy in a room to decrease by 60 dB after the source emission has stopped . The values of RT60 may range from fractions of a second to a few seconds and depend upon the size of the room and the nature of the materials used in its construction. Following the Springer Handbook of Acoustics by Thomas D. Rossing, “ reverberance is probably the best known of all subjective room acoustic aspects . When a room creates too much reverberance, speech loses intelligibility because important details (consonants) are masked by louder, lingering speech sounds (the vowels). For many forms of music, ...
