Attended Noise Monitoring and Noise Profiling Method 1. The noise analyser was turned on and calibrated. 2. The noise sample was started using ‘start/stop’. 3. When background sounds such as bird calls, planes, traffic went past the instrument was paused. 4. In total each noise sample went for 5min. 5. Noise levels: LA-Min, LA-Max, LA-EQ, LA-50, LA-90. 6. Meteorological data was added later to identify wind speed and stability class at the time.
Results – Property 1 Main Noises Heard: • Wind gust/trees rustling 60 • Bird calls • Consistent machine hum 50 • Dozer movements/Track slap 40 Noise Values (dB(A)) • Dogs barking • Planes LA-Min 30 LA-Max LA-EQ Main Indications 20 LA-50 LA-90 • Max levels were associated 10 with bird calls – high pitch. • Dominant UCML sound – ventilation fans. 0 • No noticeable pattern between weather and noise Time of Sample levels.
Results – Property 2 Main Noises Heard: 60 • Wind gust/trees rustling • Bird calls 50 • Dozer movements/Track slap • Dogs barking • Planes 40 Noise Values (dB(A)) • Ulan Water Operations LA-Min • Moolarben Coal Operations 30 LA-Max LA-EQ Main Indications 20 LA-50 LA-90 • Max levels were associated 10 with bird calls – high pitch and road traffic. • Dominant UCML sound – 0 dozers and track-slap. • No noticeable pattern between Time of Sample weather and noise levels.
