Acoustics - Determination of airborne sound power levels emitted by machinery using vibration measurement - Part 1: Survey method using a fixed radiation factor (ISO/TS 7849-1:2009)
ISO/TS 7849-1:2009 gives basic requirements for reproducible methods for the determination of an upper limit for the A-weighted sound power level of the noise emitted by machinery or equipment by using surface vibration measurements. The method is only applicable to noise which is emitted by vibrating surfaces of solid structures and not to noise generated aerodynamically.
This vibration measurement method is especially applicable in cases where accurate direct airborne noise measurements, e.g. as specified in ISO 3746, ISO 3747, and ISO 9614 (all parts), are not possible because of high background noise or other parasitic environmental interferences; or if a distinction is required between the total radiated sound power and its structure vibration generated component.
The methods described in ISO/TS 7849-1:2009 apply mainly to processes that are stationary with respect to time.

Akustika - Določanje ravni zvočnih moči v zraku, ki jih povzročajo stroji, z merjenjem vibracij - 1. del: Informativna metoda s fiksnim faktorjem sevanja (ISO/TS 7849-1:2009)
Ta del standarda ISO/TS 7849 podaja osnovne zahteve za ponovljive metode za določanje zgornje meje za A-vrednoteno raven zvočne moči hrupa, ki ga oddajajo stroji ali oprema, z uporabo merjenja vibracij na površinah. Metoda se uporablja samo za hrup, ki ga oddajajo vibrirajoče površine trdnih struktur, in ne za aerodinamično ustvarjeni hrup.
Ta metoda merjenja vibracij se uporablja zlasti v primerih, ko točnih meritev hrupa, ki se prenaša neposredno po zraku, npr. kot je določeno v standardih ISO 3746[7], ISO 3747[8] in ISO 9614 (vsi deli)[12], ni mogoče izvesti zaradi močnega šuma v ozadju ali drugih parazitskih motenj v okolju, ali kadar je treba razlikovati med skupno izsevano zvočno močjo in njeno komponento, ki ustvarja strukturne vibracije.
OPOMBA 1: Ena od aplikacij tega dela standarda ISO/TS 7849 je razlikovanje med sevanjem zvočne moči v zraku, ki jo ustvarjajo strukturne vibracije, in aerodinamičnimi komponentami zvočne moči. Pri standardih ISO 3746[7] in ISO 9614 (vsi deli)[12] takšno razlikovanje ni izvedljivo.
OPOMBA 2: Težave se lahko pojavijo, če hrup ustvarjajo majhni deli površin strojev (drsni kontakti, npr. ščetka na drsnem obroču ali komutator in ščetka v električnih strojih).
Metode, opisane v tem delu standarda ISO/TS 7849, se uporabljajo predvsem za procese, ki so stacionarni glede na čas.
