Abstract

Disclosed is a system and method for producing a sound having a certain frequency range to maintain laying hens in more stable and comfortable conditions. The system comprises a basic wave generator for generating a pair of first basic waves having the same phase and a pair of second basic waves having opposite phases, a relaxation wave generator for generating a pair of relaxation waves by combining the pair of first basic waves and the pair of second basic waves with time, a modulator for generating a pair of relaxation sounds by modulating the pair of relaxation waves with a sound wave having an audible frequency, and an audio output unit composed of two left and right parts such that stereo sound is outputted, for receiving the pair of relaxation sounds and outputting the pair of relaxation sounds to the left and right parts, respectively.

Claims

1. A system for relaxing laying hens, comprising:

a relaxation sound generator for generating a relaxation sound having the same frequency range as an alpha wave having a frequency range of 7 Hz to 15 Hz to make poultry relaxed;

an audible sound generator for generating an audible sound heard by the poultry;

a modulator for modulating the relaxation sound by mixing the relaxation sound with the audible sound; and

an audio output unit for outputting the modulated relaxation sound.

2. A system for relaxing laying hens, comprising:

a basic wave generator for generating a pair of first basic waves having the same phase and a pair of second basic waves having opposite phases;

a relaxation wave generator for generating a pair of relaxation waves by combining the pair of first basic waves and the pair of second basic waves with time;

a modulator for generating a pair of relaxation sounds by modulating the pair of relaxation waves with a sound wave having an audible frequency; and

an audio output unit composed of left and right parts such that stereo sound is outputted, for receiving the pair of relaxation sounds and outputting the pair of relaxation sounds to the left and right parts, respectively.

3. The system as set forth in claim 2, wherein frequencies of the pair of first basic waves and the pair of second basic waves combined in the relaxation wave generator are changed with time.

4. The system as set forth in claim 2, wherein the audio output unit is a public address speaker disposed in a space where poultry can hear the modulated relaxation sound.

5. The system as set forth in claim 2, wherein the pair of relaxation waves has a frequency range of 5 Hz to 15 Hz.

6. The system as set forth in claim 5, wherein the audio output unit is a public address speaker disposed in a space where poultry can hear the modulated relaxation sound.

7. The system as set forth in claim 2, wherein the relaxation wave generator produces a pair of relaxation wave periodically by combining the pair of first basic waves and the pair of second basic waves with time.

8. The system as set forth in claim 7, wherein the audio output unit is a public address speaker disposed in a space where poultry can hear the modulated relaxation sound.

9. A method for relaxing poultry by letting the poultry hear a relaxation sound, comprising;

a first step of outputting the relaxation sound having a frequency increased with time to cheer up the poultry;

a second step of outputting the relaxation sound having a frequency decreased and increased with time to relax the poultry, and

a third step of outputting the relaxation sound having a frequency decreased with time to put the poultry to sleep.

10. The method as set forth in claim 9, wherein the first step comprises outputting the relaxation sound having a frequency increased gradually from 10 Hz to 15 Hz.

11. The method as set forth in claim 10, wherein mute is maintained for a predetermined time between the first step and the second step or between the second step and the third step.

12. The method as set forth in claim 9, wherein the second step comprises outputting the relaxation sound having a frequency increased and decreased periodically within a range of 6 Hz to 12 Hz.

13. The method as set forth in claim 12, wherein mute is maintained for a predetermined time between the first step and the second step or between the second step and the third step.

14. The method as set forth in claim 9, wherein the third step comprises outputting the relaxation sound having a frequency decreased gradually from 10 Hz to 5 Hz.

15. The method as set forth in claim 14, wherein mute is maintained for a predetermined time between the first step and the second step or between the second step and the third step.
