Noise levels are NEVER adhered to….
Noise–well above the allowable 10 decibels above ambient–is the take-away from data gathered on December 13, 2013. Stephen Ambrose charted readings HMMH recorded that night. Green areas show the allowable limit. Readings above that level are highlighted in pink. He notes that the turbines were not even running at full power.
Question marks indicate anomalies in the measurements.
