A BS4142 assessment was requested by BlueSky Apartments, Swindon as fan noise was impacting upon parts of ‘The Sanctuary’ a group of high specification apartments in a modern building. The survey was completed by Soundguard Acoustics Ltd and the problem quickly determined as inappropriately externally mounted fan isolation that was creating a vibration pathway and noise transmission into the building.
