[QUOTE="windshear, post: 1128629, member: 619"] RT60 is not really a practical measurement in a home environment. It basically amounts to the sound level required to drop by 60dB. The problem is most small usb capsule based measurement mics have an inherant noise floor of about +/- 45dB. So your source signal needs to be 60db above that to get a good indication of whats going on. Also the measurement to be technically correct needs the point source to be a dodecahedron based speaker to fire in all directions to give an accurate "space" interaction. Also REW extrapolates this to approximate what it would be if measured. The important thing with any time based decay is to ensure you have uniformity in the time vs frequency domain. This ensures you dont have ringing at a frequency or importantly only treating a range of frequencies to the detriment of the whole range. Lastly dont overlook the fact everyone has a preference to a certain type of sound either through familiarisation or training. There is no right or wrong as long as it works for you, but there are best practices to achieve a relative standardisation and repeatable predictability. [/QUOTE]
