This Technical Report gives basic requirements for reproducible methods for estimating the sound emitted by machines or equipment by using surface vibration measurements. The method is especially applicable in cases where accurate direct airborne noise measurements as specified in ISO 3741, ISO 3742, ISO 3743, ISO 3744 and ISO 3745 are not possible because of high background noise or other parasitic environmental influences. The methods are only applicable to noise which is emitted by vibrating surfaces of solid structures and not to noise generated aerodynamically. The method described in this Technical Report applies mainly to processes which are stationary with respect to time. Research into the possibility of extending these techniques to non-stationary processes is, however, encouraged.
