Transformers often generate a low-frequency hum and structure-borne vibration that can travel through walls, floors and supporting frames. In many facilities, this noise becomes noticeable in control rooms, office areas, residential-adjacent sites, hospitals, data rooms, utility buildings and plant rooms.
Effective transformer noise control helps improve acoustic comfort, reduce disturbance to people working nearby and support better site planning. The right solution depends on the transformer type, load condition, enclosure layout, room geometry and surrounding structures. For this reason, every project should begin with a site survey and acoustic consultation.
