TA Zgomot A.2 Prognoza zgomotelor

A.2.1 Prognoza:• Prognoza aproximativa (simplificata dupa VDI 2714)

Procedura simplificata, usor de realizat, nu utilizeaza anumite aspecte estimare ponderata.

• Prognoza detaliata (conform ISO 9613-2)procedeu exact (+/- 3 dB pana la 1000m distanta),necesita cunostinte exacte ale caii de dispersie a zgomotului,costisitoare, de obicei realizabila doar utilizand calculatorul.

Nivelul de intensitate a zgomotului LW este marimea acustica pentru emisia de zgomot a unei surse.

Puterea zgomotului W este energia emanata de zgomot, care circula printr-o suprafata pe unitate de timp si care acopera complet sursa de zgomot.

Zgomotele pot actiona deosebit de suparator ca urmare a structurilor in timp sau aparitiilor spectrale, acestea fiind considerate in TA Zgomot ca fiind adaosuri:

Adaos KI pentru mentinerea impulsului0, 3 oder 6 dB

• Adaos KT pentru mentinerea tonului si informatiei 0, 3 sau 6 dB

Zgomot de frecvente variate KI si KT = 0 dB

Zgomot cu impuls mentinut KI = 3 sau 6 dB
