How do I record irritating "humming" bakground noise?

Posted: Wed Sep 08, 2010 10:33 am
Hello,
Do anyone know where I can find good instructions on how to record background noise, and how to get presentable data from the recorded files?

I have a very irritating "humming" background noise in my apartment 365 days per year. The noise can be compared with the sound from a very big high voltage transformator.
I have installed Audicity 1.2.6 on my laptop, and recorded some testdata with the inbuilt microphone. I do get the noise on files, but I don“t know how to use Audicity to present redable information, like Hz, db, amplitude and so on. I would like to record the noise in the best possible way, so the recorded files can be used like "evidence" in dialogs with the municipal, who I intend to contact for help with locating the sorce of the noise.

The file "test2.aup" is a short example of the recorded noise.

Many Thanks!
/Mike

Audacity AUP files aren't sound files. Try exporting As WAV and post two or three seconds.

It could be a transformer or it could be you live over an air conditioner or vent system that never goes off. Where, in general, are you? That will tell us which power frequency to look for. I live in the US which has 60 Hz power.
