Hi there, EASE can give us the values of this RT time EDT, T20, T30:
My questions are
- Is there any book that describes how human feel about this EDT, T20, T30.
- If we are to optimize the room to have an optimal RT time which value should we focus on?
- Is there a standard that outlines an optimal RT value for specific room size, ISO? ASTM?
-
Thank ou
I really appreciate your inputs

Hi!

- Is there any book that describes how human feel about this EDT, T20, T30.
There are many, but you can search for these:
. Acoustics and Psychoacoustics - David M. Howard ; Jaimie A. S. Angus
. Hearing, An Introduction to Psychological and Physiological Acoustics - Stanley A. Gelfand
. Psychoacoustics: Facts and Models - Hugo Fastl ; Eberhard Zwicker

- If we are to optimize the room to have an optimal RT time which value should we focus on?
It has a strong dependence of which type of activity is/will be developed

- Is there a standard that outlines an optimal RT value for specific room size, ISO? ASTM?
I honestly do not know Rolling Eyes there are books, but not sure if there is a specific standard

There is the german standard DIN 18041 "Hörsamkeit in Räumen - Anforderungen, Empfehlungen und Hinweise für die Planung" (Acoustic quality in rooms - Specifications and instructions for the room acoustic design).
