1. Sensor and method for detecting very low frequency acoustic signals

2. Watson was in fact listening to very low-frequency radio emissions caused by nature.

3. Watson was in fact listening to very low- frequency radio emissions caused by nature.

4. There is disclosed a sensor (100) and method for detecting very low frequency acoustic signals.

5. 60 infra-sound stations using microbarographs (acoustic pressure sensors) to detect very low-frequency sound waves.

6. To coordinate the movements of groups who are out of sight, elephants and whales use very low frequency sounds that circumvent obstacles and carry over long distances.

7. Pre-and postoperative ballistocardiograms were analyzed in approximately 100 patients with surgically Amenable cardiovascular diseases.: One might have anticipated that the nature of very low-frequency modes might be Amenable to semiclassical analysis.: With the exception of liver metastases of colorectal cancer, tumour deposits are almost always multiple and seldom Amenable to resection.
