Acoustics. Recommended practice for the design of low-noise workplaces containing machinery - Sound propagation and noise prediction in workrooms1 Scope In this part of ISO 11690, sound propagation in a room is considered together with the prediction of sound pressure levels and of noise immission at the workplace. Details of the description of the physical phenomena involved in a noise prediction scheme are strongly dependent on the situation being considered and the way this situation is modelled (input parameters, calculation techniques). This dependency is surveyed and the methodology for
