Why Reducing White Noise is Essential for Capturing Clear EVPs

And How the SB11 ANC and ANC Mini Are Game-Changers for Paranormal Investigators
What Is White Noise and Why Does It Matter?
White noise is the static, hissing background sound generated by spirit boxes and similar devices. While it’s thought to help spirits communicate by offering a soundbed to manipulate, too much white noise can drown out the very voices you’re trying to capture . This can make evidence harder to review and even lead to false positives or misinterpretation.
The goal isn’t to eliminate all noise-some is necessary for spirit manipulation-but to reduce the overwhelming static so the intelligent responses come through clearer .
