  • Noise noise control measures IOSH

    Where a risk assessment identifies that individuals are exposed to hazardous noise levels at work, employers need to introduce measures to control the associated risks. These measures usually involve a combination of methods, such as controlling the noise at source, redesigning the layout of workstations and re-organising the work processes.
