A graph of the hourly equivalent sound level(Leq), maximum sound level(Lmax), 90th percentile sound level(L90), minimum sound level(Lmin), and minimum equivalent sound level over the monitoring period(min Leq) is presented... The one-hour Leq is an energy-averaged level and is considered a good single number descriptor of human response to environmental noise effects.  1, record 1, English, - energy%2Daveraged%20level

integrating sound level meter. Provides a direct measure of the sample equivalent continuous sound level Leq... The difference with a conventional sound level meter is that an integrating s. l. m. gives the same weight to all the earliest and latest parts of the signal, while a conventional one gives greater weight to the more recently occurring part of the sound signal than to the older parts.  2, record 3, English, - integrating%20sound%20level%20meter

Le sonomètre intégrateur ressemble à l'audiodosimètre. Il établit un niveau sonore équivalent sur une période d'enregistrement des bruits. La principale différence est qu'il ne marque pas l'exposition personnelle, puisqu'il est tenu à la main plutôt que d'être porté sur soi. Le sonomètre intégrateur établit les niveaux sonores équivalents en un endroit précis, sur un bruit donné, même si le niveau sonore réel de ce bruit varie continuellement. Cet instrument utilise un taux d'échange préprogrammé avec une constante temporelle équivalant au mode LENT du sonomètre ordinaire.  2, record 3, French, - sonom%C3%A8tre%20int%C3%A9grateur
