1. A sound outputting apparatus, comprising:
- an electro-acoustic conversion section disposed in a housing and configured to acoustically reproduce a first sound signal;
a sound collection section configured to collect sound outside said housing and output a second sound signal;
a surrounding noise evaluation section configured to evaluate surrounding noise outside said housing based on the second sound signal; and
a control section configured to perform predetermined control based on a result of the evaluation of said surrounding noise evaluation section, the control section determining whether the surrounding noise outside said housing results from, based on an evaluation by the surround noise evaluation section;
(1) sound leakage from the reproduction of the first sound signal, and(2) a noisy listening environment,such that the predetermined control includes maintaining an output sound volume when both (1) and (2) are relatively high, and lowering the output sound volume when only (1) is relatively high.

12. A sound outputting method, comprising the steps of:
-
acoustically reproducing a first sound signal, the step being executed by an electro-acoustic conversion section disposed in a housing; collecting sound outside the housing and outputting a second sound signal, the step being executed by a sound collection section; evaluating surrounding noise outside the housing based on the second sound signal; performing predetermined control based on a result of the evaluation at the surrounding noise evaluation step; and determining whether the surrounding noise outside said housing results from, based on an evaluation by the evaluating step; (1) sound leakage from the reproducing of the first sound signal, and (2) a noisy listening environment, such that the predetermined control includes maintaining an output sound volume when both (1) and (2) are relatively high, and lowering the output sound volume when only (1) is relatively high.

14. A sound outputting system, comprising:
-
a headphone apparatus; and a sound outputting apparatus to which said headphone apparatus is connected; said headphone apparatus including an electro-acoustic conversion section disposed in a housing of said headphone apparatus and configured to acoustically reproduce and output a first sound signal from said sound outputting apparatus, and a sound collection section configured to collect sound outside said housing of said headphone apparatus, said sound outputting apparatus including a surrounding noise evaluation section configured to evaluate surrounding noise outside said housing based on the second sound signal obtained by the sound collection by said sound collection section, and a control section configured to perform predetermined control based on a result of the evaluation of the surrounding noise outside said housing by said surrounding noise evaluation section, the control section determining whether the surrounding noise outside said housing results from, based on an evaluation by the surround noise evaluation section; (1) sound leakage from the reproduction of the first sound signal, and (2) a noisy listening environment, such that the predetermined control includes maintaining an output sound volume when both (1) and (2) are relatively high, and lowering the output sound volume when only (1) is relatively high.
