Paper Abstract

Over a two year period, measurements of the daily levels of 74.91 kHz. acoustic signals transmitted between oil - immersed acoustic waveguides [AWG] correlated fairly well [20 to 70%] with daily tidal levels controlled by the sun and moon's gravitational forces on earth. Consequently, it is reasoned, the AWG measurements are also in some sense or degree related to these forces. Assuming that the daily AWG measurements are indeed gravity related, then a 1 Hz. to 15 Hz. pulsatory background noise or jitter which was found to be associated with the AWG signal with a peak response at 6 Hz. could possibly be indicative of gravitational - type of waves or disturbances occurring somewhere in space. In thls regard, it is interesting to note that pulsars have been studied as possible sources of gravitational waves or disturbances, and that the pulsed radio energy emissions of >90% of pulsars catalogued occur in the <1 Hz. to 20 Hz. frequency range and peak emission also occurs at 6 Hz. This raises the possibility of a gravity - type of low frequency background noise or hum at that frequency.
