Comparing June 2026 to the same month in previous years at Feldbergstrasse reveals some notable differences. The average of 68.7 dB this year is slightly lower than the averages from 2020 through 2023, which ranged from 69.8 to 72.5 dB, and similar to 2025. The maximum of 93.2 dB in June 2026 is the highest recorded for any June since 2020, exceeding the previous peak of 91.9 dB in 2023. The year 2024 stands out as an anomaly, with both average and maximum values at just 24.1 dB, likely indicating a sensor outage or data error. Excluding 2024, the historical averages have been fairly stable, but the 2026 maximum represents a new high point.

Since 2020, the overall average noise level at Feldbergstrasse has been 68.7 dB, with an all-time maximum of 93.2 dB. The 99th percentile value of 88.2 dB indicates that extreme noise events above that level are rare outliers. The quietest time of day historically is the early overnight period from midnight to 03:00, averaging 64.6 dB, while the late morning from 09:00 to noon averages 71.7 dB. The all-time lowest noise level recorded at Feldbergstrasse was 24.1 dB, which occurred in June 2024, though this value is likely due to a measurement issue rather than a genuine quiet period.

The decibel (dB) scale is logarithmic, meaning that a 10 dB increase represents a tenfold increase in sound intensity. For context, a quiet room measures around 30 dB, normal conversation is roughly 50 to 60 dB, and nearby street traffic can reach 70 to 80 dB.
