When it comes to building service plant, there can be various noise issues that arise. Here are some common examples:
- Machinery Noise: Building service plant often includes equipment such as generators, chillers, pumps, compressors, and HVAC systems. These machines can generate significant noise during their operation, especially if they are not adequately enclosed or if their maintenance is neglected.
- Ventilation and Exhaust Noise: Ventilation systems, including fans and blowers, are essential for maintaining air quality and circulation within a building. However, these systems can produce noise, especially if they are not properly designed, maintained, or equipped with noise-reducing features (e.g. attenuators). Exhaust systems, such as those for boilers or diesel generators, can also contribute to noise levels. Suppliers of attenuators in the UK include IAC, Caice, and Allaway.
- Vibration: Some equipment can generate vibration that transmits through the building structure. This vibration can not only create noise but also cause physical discomfort if not properly addressed. Suppliers of anti-vibration products in the UK include Tico, CDM Stravitec and Mason UK.
- Ductwork and Piping Noise: The movement of air or fluid through ductwork and piping systems can generate noise, particularly if there are issues like loose fittings, inadequate insulation, or excessive flow rates. The noise can manifest as hissing, rattling, or banging.
- Transmission through Structures: Noise generated within a plant room can transmit through the building’s structural elements, such as walls, floors, or ceilings. If the structure lacks proper sound insulation or if there are weaknesses, the noise can propagate into occupied areas and cause disturbances.
It’s important to note that noise issues can vary depending on the specific design, equipment, and maintenance practices. To mitigate noise problems, it is crucial to incorporate appropriate noise control measures during the design phase and regularly maintain and inspect the equipment and systems.
