Résumé

Dans ce document, l'auteur décrit l'évolution des mesures de l'acoustique des auditoriums, qui tiennent maintenant compte d’autres critères que le temps de réverbération. On a défini des grandeurs visant la parole et la musique. Il a été démontré qu'il existe une bonne corrélation entre deux types différents de mesures de la parole et le degré d'intelligibilité de celle-ci. Les recherches accomplies ont permis de dégager un consensus concernant le fait qu'un petit nombre de grandeurs explique presque toute la variance de l'évaluation subjective de la qualité de l'acoustique des salles de concert. Ces nouvelles grandeurs, qui ne consistent qu'en simples additions d'énergie pendant divers intervalles de temps ou en indices d'affaiblissement de l'énergie sonore, peuvent être facilement mesurées dans les salles.
