Abstract

In a first aspect, an apparatus 10 is provided to detect noise in a body of water 22 indicative of a person falling into the body of water and to raise an alarm in response to such detection. The body of water may comprise a swimming pool. A hydrophone 14 may be immersed in the body of water in order to detect noise indicative of a person falling into the body of water. In another aspect, an apparatus is provided including a device carried by a swimmer (see figure 9), the device having a means for sensing movement in a body of water, wherein the apparatus raises an alarm if there is a substantial lack of movement. The movement sensing means may comprise a hydrodynamic pressure sensor. An alarm may be raised if the lack of movement persists for a predetermined period of time. In a further aspect an alarm apparatus is provided including both of the above mentioned apparatus.
