Abstract

Il metodo comprende: l'effettuare misurazioni preminari per determinare la relazione (funzione) tra le caratteristiche fisiche che influenzano il processo tecnologico e l'intensità e/o lo spettro del suono che deriva e/o è emesso durante il processo; il memorizzare detta funzione e/o i suoi punti e/o limiti critici caratteristici del processo tecnologico; il rivelare l'intensità e/o lo spettro del suono che deriva e/o è emesso durante il processo tecnologico; il confrontare detta intensità e/o spettro con la funzione e/o i punti e/o i limiti critici memorizzati; e l'intervenire nel processo tecnologico se esiste una differenza da detta funzione, e/o punti e/o limiti critici raggiunti. La disposizione comprende: un sensore sonoro (1); un'unità di misurazione e di valutazione (7) collegata all'uscita del sensore sonoro (1); e un dispositivo d'uscita (8) collegato all'uscita dell'unità di misurazione e di valutazione (7).The method includes: making preminary measurements to determine the relationship (function) between the physical characteristics that influence the technological process and the intensity and / or spectrum of the sound that derives and / or is emitted during the process; memorizing said function and / or its critical points and / or limits characteristic of the technological process; revealing the intensity and / or spectrum of the sound that derives and / or is emitted during the technological process; comparing said intensity and / or spectrum with the stored function and / or points and / or critical limits; and intervening in the technological process if there is a difference from said function, and / or critical points and / or limits reached. The arrangement includes: a sound sensor (1); a measuring and evaluation unit (7) connected to the sound sensor output (1); and an output device (8) connected to the output of the measurement and evaluation unit (7).
