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 electric signal; and
a control section configured to perform predetermined control based on a result of the evaluation of said surrounding noise evaluation section.
