Sound Regulation Apparatus, Method or Program

Sound regulation method that is able to change an environmental sound into an input sound, change an input sound into a converted sound with arbitrarily regulatory frequency component, arbitrarily regulatory amplitude or both, change a converted sound into an output sound transmitted to environment, change an output sound together with environmental sound into an input sound again, and change this input sound further into a converted sound,

• comprising a series of steps of:
• receiving an environmental sound derived from arbitrary environment as an input sound;
• converting said input sound into a converted sound with arbitrarily regulatory frequency component including frequency component that approximates to sine-wave oscillator, sawtooth-wave oscillator, square-wave oscillator or triangle-wave oscillator, arbitrarily regulatory amplitude or both;
• and
• transmitting said converted sound as an output sound to said environment;
• whereby receiving a synthetic sound synthesized with said output sound and environmental sound as an input sound again, and converting this input sound further into a converted sound.

Sound regulation program that is in sound regulation apparatuses able to change an environmental sound into an input sound, change an input sound into a converted sound with arbitrarily regulatory frequency component, arbitrarily regulatory amplitude or both, change a converted sound into an output sound transmitted to environment, change an output sound together with environmental sound into an input sound again, and change this input sound further into a converted sound,

• comprising a set of instructions for functioning as:
• input means that receives an environmental sound derived from arbitrary environment through AD conversion as an input sound;
• memory means that writes said input sound to a memory;
• conversion means that reads said input sound from said memory, and converts said input sound into a converted sound that contains arbitrarily regulatory frequency component including frequency component that approximates to sine-wave oscillator, sawtooth-wave oscillator, square-wave oscillator or triangle-wave oscillator, arbitrarily regulatory amplitude or both;
• memory means that writes said converted sound to a memory;
• and
• output means that reads said converted sound from said memory, and transmits said converted sound as an output sound to said environment through DA conversion;
• whereby said input means receives a synthetic sound synthesized with said output sound and environmental sound as an input sound again, and said conversion means converts this input sound further into a converted sound.
