Evaluation of sonic environment in prospective middle-class apartment building in Demak regency

The location of prospective middle-class apartment building in Demak regency is adjacent with roadway and double track railway. The high mobility of the various modes of transportation in these locations could potentially for excessive noise exposure above the noise level standard. By conducting noise measurement and subjective survey, this study aims to investigate the sonic environment of the site and its effect on surrounding communities. Measurement of noise was carried out in thirty-six positions by using calibrated H6 Zoom and Sound Level Meter. To determine the distribution of LAeq, the measurement results are visualized using QGIS, Geographic Information System based software. In addition, subjective survey was conducted to investigate the perception of annoyance from people living nearby the location. The result is to provide a suggestion toward the design guideline to create a good acoustics quality that meets the standard for building.
