SIST EN ISO 20270:2023(Main)
Acoustics - Characterization of sources of structure-borne sound and vibration - Indirect measurement of blocked forces (ISO 20270:2019)
EN ISO 20270:2022

This document specifies a method where a vibrating component (a source of structure-borne sound or vibration) is attached to a passive structure (or receiver) and is the cause of vibration in, or structure-borne sound radiation from, the assembly. Examples are pumps installed in ships, servo motors in vehicles or machines and plant in buildings. Almost any vibrating component can be considered as a source in this context.
Due to the need to measure vibration at all contact degrees of freedom (DOFs) (connections between the source and receiver), this document can only be applied to assemblies for which such measurement is possible.
This document is applicable only to assemblies whose frequency response functions (FRFs) are linear and time invariant.
The source can be installed into a real assembly or attached to a specially designed test stand (as described in 5.2).
The standard method has been validated for stationary signals such that the results can be presented in the frequency domain. However, the method is not restricted to stationary signals: with appropriate data processing, it is also applicable to time-varying signals such as transients and shocks (provided linearity and time invariance of the FRFs are preserved).
This document provides a method for measurement and presentation of blocked forces, together with guidelines for minimizing uncertainty. It provides a method evaluating the quality of the results through an on-board validation procedure but does not comment on the acceptability or otherwise of the results.

Acoustics - Noise from shooting ranges - Part 6: Sound pressure measurements close to the source for determining exposure to sound (ISO 17201-6:2021)
EN ISO 17201-6:2022

This document specifies methods for recording the time history of the sound pressure produced either by shooting with calibres of less than 20 mm, or by detonation of explosive charges of less than 50 g TNT equivalent, within the shooting range at locations of interest, regarding the exposure to sound of the shooter, or any other person within the shooting range. The time history of the sound pressure can be the basis for further analyses of this type of sound at the locations of interest.

Acoustics - Determination of airborne sound power levels emitted by machinery using vibration measurement - Part 2: Engineering method including determination of the adequate radiation factor (ISO/TS 7849-2:2009)
CEN ISO/TS 7849-2:2022

This part of ISO/TS 7849 gives basic requirements for a reproducible method for the determination of the
sound power level of the noise emitted by machinery or equipment by using surface vibration measurements,
together with the knowledge of the machinery specific sound radiation factor in the frequency bands. 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[7], ISO 3747[8], and ISO 9614 (all parts)[14], 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.
NOTE 1 One of the applications of this part of ISO/TS 7849 is the distinction between the radiation of airborne sound
power generated by structure vibration and the aerodynamic sound power components. Such a distinction is not feasible
with ISO 3744[5], ISO 3745[6], ISO 3746[7] and ISO 9614 (all parts)[14].
NOTE 2 Problems may occur if the noise is generated by small parts of machinery surfaces (sliding contacts, e.g. slip
ring brush or the commutator and the brush in electrical machines).
The methods described in this part of ISO/TS 7849 apply mainly to processes that are stationary with respect
to time.
Recommendations on the selection of frequency bands are given in Annex C

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)
CEN ISO/TS 7849-1:2022

This part of ISO/TS 7849 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[7], ISO 3747[8], and ISO 9614 (all parts)[12], 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.

Acoustics - Field measurements of airborne and impact sound insulation and of service equipment sound - Survey method (ISO 10052:2021)
EN ISO 10052:2021

This document specifies field survey methods for measuring
a) airborne sound insulation between rooms,
b) impact sound insulation of floors,
c) airborne sound insulation of façades, and
d) sound pressure levels in rooms caused by service equipment.
The methods described in this document are applicable for measurements in rooms of dwellings or in
rooms of comparable size with a maximum of 150 m3.
For airborne sound insulation, impact sound insulation and façade sound insulation the method gives
values which are (octave band) frequency dependent. They can be converted into a single number
characterising the acoustical performances by application of ISO 717-1 and ISO 717-2. For heavy/soft
impact sound insulation, the results also are given as A-weighted maximum impact sound pressure
level. For service equipment sound the results are given directly in A - or C -weighted sound pressure
levels.
