Program Overview
Aircraft Departures/Arrivals Noise Monitoring

Lake Tahoe Airport monitored noise at six sites in the vicinity of the airport (see map above) following an approved monitoring protocol. All exceedances logged by these monitors are documented and categorized in quarterly and annual noise reports sent to TRPA. While monitoring of exceedances has continued, the ability to differentiate between aircraft and non-aircraft exceedances was not possible, therefore data quality is low and only total exceedances (including aircraft, natural sources (e.g. wind, lightning, wildlife) and other anthropogenic sources) are reported and trend is not assessed. Past monitoring data shows that an average of 17 percent of exceedances were caused by aircraft, however the percent of exceedances per year caused by aircraft varies greatly year to year, making any judgement on how many of the total exceedances are caused by aircraft in any given year inestimable.
