Tracey writes:
We investigate and deal with reported poltergeist cases, unusual or paranormal phenomena. And, as we live close to Denbigh Castle, we sweep the area on a regular basis for paranormal activity.
This usually takes a few hours using digital cameras, EMF meters, digital voice recorders and so on. Only one EVP has been caught so far. That is of a bugle call from the great kitchen area.
Upon investigation of the area it has become apparent that Denbigh Castle has what we would call residual haunting. This means that the phenomena has very low frequency and no interaction. It is like a recording of incidents from the past imprinted in the atmosphere and occasionally replaying. 
Denbigh Paranormal Unit was set up by Tracey and Steve nine years ago and they hold vigils for charity at a number of historic places across the region.

It sounds like a woman singing in another language maybe, definitely something paranormal.
