Sound Meter to Trace Sources of Noise?

There is a room in my house where my tinnitus goes nuts. I'm thinking it's from a transformer or compressor or something. Does any one know of a sound meter that could trace the source of these noises?

 

There are apps you can download onto your phone. My best guess is that those rooms are just really quiet so you are hearing your T louder.

 

I think you can hire them but as Jkph75 days you can download free apps to give you a rough reading..lots of love glynis

 

what you'd want to do is get a relatively high-quality microphone, record the audio, and then use a program like Spek (http://spek.cc/) to analyze the sound file and see if there's any crazy high-frequency harmonics going on.

I have personally noticed that my T can get sort of reactive to oppressively high-pitched electronics noises; I notice the same thing in one room in my house, and using Spek I note some low-decibel but very reliable ambient sounds in the 14khz and 17khz bands.
