Abstract: A programmable, customizable system, method, and apparatus for attracting and stimulating aquatic animals are disclosed. The present invention provides for the underwater playback of digitally prerecorded “signature” sounds of prey, and of prey being attacked and eaten, in order to attract fish and other species and stimulate them to strike and feed more aggressively. Playback is achieved by selecting any of a plurality of signature sound recordings stored on a memory device which is located and controlled above water. One sound, all sounds, or a selected sequence of sounds may be selected from the memory device to be played underwater. Underwater playback is achieved by use of a submersible transducer device which may function as both a speaker and a hydrophone. Underwater playback may be customized and controlled above water by providing a number of customized operational modes.

In this way, birds are dissuaded from gathering in particular areas where the ultrasonic device is in use, and humans are provided a more healthy and disease-free environment.

Abstract: An electronic animal lure for generating an animal call pattern by combining actual stored analog animal sounds with a micro controller. The animal sounds are stored in an analog storage device. A micro controller selects and addresses one of the pre-stored sounds then generates the signals to cause the storage device to play back the sound. The micro controller then selects a period of time delay before selecting and addressing the next sound to be played. Both time delays and sound selections are accomplished by use of an algorithm stored in the micro controller. The algorithm uses an onboard timer counter to generate a random number that is placed in a software counter causing the software counter to cycle for a period of time, creating a constantly varying time period between animal calling sounds. The algorithm also uses the onboard timer counter to select one of the stored sounds.

Abstract: A method is provided to estimate acoustic impacts to marine animals within a chosen area. The method begins with data collection on types of acoustic sources to be modeled, animal assemblages in the chosen area, environmental characteristics of the area and on relevant environmental regulations. An acoustic model, appropriate for the chosen area and its environmental characteristics, is then selected and generates a source footprint of all sources to be located at the site. The marine animal distribution is then overlaid onto the acoustic propagation at the site. The marine animal distribution is time-weighted to correspond with the proposed acoustic source usage, as well as short term and seasonal marine animal behavior patterns. The total number of impacted marine animals is then calculated. Impacts are calculated by species, source, scenario and season. The calculated number is then rounded upwards to the next whole individual, pod, or group, depending on the animals' behavior patterns.
