Noise Monitoring Terminal 1-Second Data

This page allows you to access the raw 1-second noise data from each of the four noise monitoring terminals owned by the City of Sunnyvale.  The reports are posted weekly in a .csv format that can be downloaded for further analysis.  Note this data set contains all noise events, not just those associated with an aircraft overflight and no aircraft correlation data is included.   The data archive goes back to November 1, 2020 when the noise monitoring terminals went live.

The 1-second values in the Excel file are reported in A-weighted decibels (dBA) as shown in the key below.
