Also at 4kHz the reverberation is around 80ms, on the RT60 its over 500ms
The Mode at around 65Hz is around 150ms on this graph, on the RT60 it is over 600ms. Note the Duration was set to 150 (im guessing ms).
This is the corresponding waterfall diagram.
This is the RT60, which seems to show a totally untreaded room, which is not the case! Markers of the Impuls were set at 0 and 340ms This is the impuls response measured in the studio using the Log squared algorithm just for more information i changed the impuls to "Log Squared Impulse" to show me the first impuls at 0dB
FUZZMEASURE ACOUSTISOFT PROFESSIONAL
I measured in my living room and in a professional studio, and both times i had the signal lose 60dB in less than 50ms. but my measurement has -60dB in less than 50ms, which is not normal. but which is the right amount? i would think i should mark time 0 (direct signal) until the signal reaches -60dB (RT60), which would be logical for me to measure RT60 over all frequencies. How much of the the Impulse response should i mark? every time i move the bounderies of the impuls, the waterfall changes drastically, which is obvious. RT60 and the waterfall diagram dont correspond at all!!ģ. on the waterfall diagram i see reverberation though. for instance at Hz i get reverberation of 0ms. i used the minimum phase function and used the RT60, RT30 but they give me odd information. I would like to compare the reverberation times of my studio rooms to others, but i just dont know how. is there any way to measure the reverberation time in fuzzmeasure? i would like to have an RT60 over all frequencies (so just one time instead of for all frequencies). but if i move the loudspeaker slighty, i get a totally different frequency response, therefore there must be some room influence happening here also! im pretty confused here, to say the leastĢ. what does the frequency response really show me? is it the direct signal from loudspeaker to mic? or is it an average? it seems to be the same frequency response as the time 0 on the waterfall diagramm, so i would think its the direct signal. There are a few things in fuzzmeasure i still cant grasp and would appreciate a little help from you guys!ġ. Im finalizing the paper now and it has to be done very soon, so i hope i can get some help here. I am writing a diploma thesis about acoustics and acoustical measurements at the moment and am using Fuzzmeasure to measure different rooms and test acoustical treatments. so i decided to come here and see if someone can help me.Ī few quesions about frequency, reverberation and waterfall It gives professional users speed and precision in making these adjustments.I Have asked this question over at the Fuzzmeasure Support site, but have not gotten any replies yet. ETF provides a psychological model of the human hearing system that more closely approximates what is actually heard, giving inexperienced listeners the capability of measuring their systems more accurately. This is acheived by using a sweep test signal that shapes itself to the particular background noise in the given environment. Adjusting a system for perfection as measured on a spectrum analyzer does not result in a system that sounds "flat", as it should This gives the user an unprecedented resolution in diagnosing room problems as well as evaluating the effectiveness of room treatment or modification for a specific resonant frequency. The reason for this is that human ears work differently than spectrum analyzers. It has long been known by professional sound installers that setting frequency response with an EQ and RTA results in a system that does not sound correct to the trained or experienced ear. The PSD / Sweep add on provides the user with the low frequency room measurement power to see the room response in terms of individual room modes rather than an approximation, such as found in other analyzers.
