  3. Noise in graphs?

    REW Forum
    Glenn from GIK has been gracious enough to give me some feedback on my REW measurement results after treating my room with some DIY treatments. He said there appears to be noise somewhere in the chain. Initially I had loaded the wrong Soundcard Calibration file. To be safe I went and created...
  4. Cable TV ground loop noise

    System Setup and Connection
    Hi all, I decided to hook up my cable box to my AVR to watch the UFC PPV. But doing so added noise to the entire system. I know it's caused by my cable provider (RG6 wire). The two solutions I know about are to remove a ground tab from the cable box or the AVR units power cables or to use an...

  6. Does the 1124DSP introduce some white noise?

    Electronic Processing/Equalization Devices
    Just got my first BFD 1124DSP. However, I will be using mine for a slightly different reason than most people here. I operate a home project studio and have taken a keen interest in tuning/measuring/treating my room. I know most shacksters are here for home theater and I totally respect all of...
  7. Measuring Noise Criteria with REW

    REW Forum
    I'd like to measure noise criterion, and I'd prefer to use REW to do so if it's possible. There have been two threads on The Shack about measuring background noise, This one in Jan 2008 and this one in Oct 2008. It was indicated the best tool was the RTA display, except that I know how to...
  8. Heat Pump Noise - How to reduce it?

    Home Theater Design and Construction
    My HT room is right by the heat pump unit. It's on the outside of the rear wall. I can hear it when the unit kicks in. Any ideas on how to fix this or limit it? The wall is already finished so any other way to reduce the noise I hear in the room?

  11. New Noise from MA RS-w12

    DIY Repair and Maintenance
    Hi all. I unplugged my Monitor Audio RS-w12 subwoofer to test another. When I plugged it back in, it is making an electrical noise from the woofer, no matter what the gain knob is set to (the volume doesn't change). It was NOT there earlier, and it is not the cable tv signal (I unplugged that)...

After that i will put up diffusors or other hard/soft materials depending of the measurements, and...

  14. HVAC + HT= Noise?

    Home Theater Design and Construction
    I will be installing some sort of HVAC in my theater next month or so and am concerned with the noise it produces. It has been bothersome since the house was built. The HVAC contractor installed a high static blower so when it reaches full speed on the ramp up, it's quite loud. Heaven forbid...
  15. Subtracting background noise from measurements?

    REW Forum
    I've been trying to lower the background noise levels so I thought how nice it would be to subtract one frequency response from another. I saved first some normal background noise with RTA and then measured the same noise with my projector on. Then saved the measurements as text files...
  16. Noise Theory

    Computers | HTPC | Media Servers
    Some weeks ago I came up with an Idea, We all have those devices that make more noise than we want them to and in that way interfere with our music/film-tracks. I figured that if I would record the sound that those devices are making (in My case I would only take the sound of my computer) and...

  20. Hearing a noise from PC

    Computers | HTPC | Media Servers
    Yesterday I became aware of a low frequency noise. It was very subtle and hardly noticeable. This is in my equipment room. I can’t say I ever noticed it before. The strange thing is it was completely in auditable when I am sitting at the computer when I stand up I could plainly hear it. It’s...
