Résumé

En général, la détermination de la puissance de bruits audibles ainsi que leur localisation se complique par des effets du local, par des bruits de fond hauts et souvent par la présence d'autres sources. La technique de mesure de l'intensité sonore à l'aide de deux microphones est trouvée prometteuse pour l'analyse des sources des bruits, là où les méthodes conventionnelles ne sont pas particulièrement pratiques. Une procédure est décrite pour mesurer directement l'intensité sonore en utilisant un "calibreur" simple et un analyseur à deux canaux.
