Abstract
A method of alerting sea cows to the existence of danger underwater includes generating a modulated acoustical signal in a predetermined source frequency band and sound pressure level and projecting the generated signal underwater in a directional manner and in a direction corresponding with the direction of travel of a motor vessel, wherein the projected modulated acoustical signal has an underwater frequency ranging between 3 kHz and 26 kHz.

A method of alerting sea cows underwater to the danger of approaching motor vessels, comprising the steps of:
- generating a modulated signal,
- transforming said modulated signal into a modulated acoustical signal, and
- projecting said modulated acoustical signal in a directional manner underwater from a motor boat in a direction corresponding with a direction of movement of the motor vessel, said projected modulated acoustical signal resulting in an underwater acoustical signal having a frequency ranging between 3 kHz and 26 kHz.
A method of alerting sea cows underwater to potential dangers, comprising the steps of:
- generating a pulsed signal,
- transforming said pulsed signal into a pulsed acoustical signal, and
- projecting said pulsed acoustical signal in a directional manner underwater, said projected acoustical signal resulting in an underwater acoustical signal having a frequency ranging between 3 kHz and 26 kHz.
A method of alerting sea cows to the danger of approaching motor vessels, comprising the steps of:
- generating a pulsed signal at a rate of between 2 and 25 times per second,
- transforming said pulsed signal into a pulsed acoustical signal, and
- projecting said pulsed acoustical signal in a directional manner underwater from a motor vessel in a direction corresponding with a direction of movement of the motor vessel, said projected pulsed acoustical signal having a beam width between 2.degree. and 18.degree. and resulting in an underwater acoustical signal having a frequency ranging between 3 kHz and 26 kHz, wherein said projected pulsed acoustical signal is audible to sea cows underwater up to a range that allows sea cows a predetermined amount of time to hear and avoid collision with the motor vessel.
