Abstract

A system for producing a sound having a certain frequency range to maintain laying hens in stable and comfortable conditions. includes 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 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.

2. The system as set forth in claim 1, 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.

3. The system as set forth in claim 1, wherein the audio output unit is a public address speaker disposed in a space where poultry can hear the modulated relaxation sound.

4. The system as set forth in claim 1, wherein the pair of relaxation waves has a frequency range of 5 Hz to 15 Hz.

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

6. The system as set forth in claim 1, 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.

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