The intensity in the building construction, populous areas, traffic congestion and the numerous noise sources, especially in the urban areas, impose the need of adequate materialization of buildings that will ensure an ideally insulated living space. Best confirmation whether the partition walls meet the required value for sound insulation is the field measurement, which reflect the actual situation taking into consideration all of the imperfections of the building process and the flanking transmission of the sound. Field measurements of 18 differenttypes of partition walls in residential buildings in Macedonia were carried out. The results are summarized in the form of conclusions, observations, and recommendations for further research in this area.
