Re: Measuring reverb time without any tools?
But it easily get much better.
I you have a simple RTA (on a phone for example) set it for the fastest release time it has.
Put in the noise-let the room "fill up" and then stop it.
Simply watch the meter as it decays-and you can get an idea of what the largest problem freq is (it will be the slowest to decay) and you can get a quick idea of the balance of the decay time over the freq range.
This same technique can be used when yo uare dealing a a very live room and a sound system. Let's say that 500Hz has the longest decay time. Then put a wide dip in the response of the system at 500Hz.
This way you are not energizing the room as much at 500Hz-so it doesn't "stand out" as much.
Yes in the measurable response there will be a dip-but in the audible response-it will sound a lot "less echoy".
It won't fix the problem-but it can help to make is not as bad.
Of course if the decay is nice and even-not much you can do in that case.
