I want to measure the sound spectrum of a hair dryer. So I did two RTA measurement: With (A) and without (B) switching on the hair dryer. And then in the "All SPL" graph I do the (A) minus (B) and generated the third graph. I hope this more or less represent the spectrum of the hair dryer...

I am using a USB microphone to do spectrum analysis. In the RTA graph, can I show the graph in dBA scale? Thank you.

I am not sure, I attached the calibration file here.

Thank you. In my computer it seems that it does affect the level. I did a test: I switch on a noisy fan, and testing it with the microphone and the SPL meter in the REW software. When I change the mic level (in Windows 10) to 70%, the result is about 65dB(A)S, but when I change it to 100%, the...

Yes I have loaded the calibration file for the microphone. In fact when I plug the microphone into my PC, and then open the REW, the REW will pop up a message notice me that I am using the UMM-6 USB microphone and it ask me to select the calibration file. Is that mean I should not change the...

I want to do some audio spectrum analysis on an appliance so I bought a Daytonaudio measurement USB microphone. I hope to use it with the REW to do the analysis. I plugged the USB microphone to my computer and tested the "RTA" and "measure" function in REW. I think they are working and it did...
