In December 2025, the Feldbergstrasse station recorded an average noise level of 68.7 dB, with a peak of 93.2 dB on December 22nd, indicating consistently high noise levels comparable to street traffic. Historical data since 2020 shows that while the average noise level has remained relatively stable, the maximum noise level in December 2025 was slightly higher, suggesting a potential increase in noise intensity.

In December 2025, the average noise level at the Feldbergstrasse station was recorded at 68.7 dB, with a maximum level reaching 93.2 dB. This peak occurred on December 22nd between 9:00 AM and 11:59 AM. The noise levels at Feldbergstrasse are considered very loud, as they fall within the 70-80 dB range, which is comparable to street traffic. Other stations with recorded values in December 2025 include Grenzacherstrasse and Zuercherstrasse148.

Looking at the historical data since 2020, Feldbergstrasse has maintained a relatively consistent average noise level, with slight fluctuations. The average noise level for December 2025 is similar to previous years, such as 2020 and 2021, where the averages were 70.3 dB and 70.0 dB respectively. However, there is a notable deviation from the unusually low average of 24.1 dB recorded in 2023 and 2022. The maximum noise level in December 2025 at Feldbergstrasse is slightly higher than the historical maximums, indicating a possible increase in noise intensity.

The highest noise level at Feldbergstrasse was recorded at 93.2 dB on December 22nd, 2025, between 9:00 AM and 11:59 AM. The all-time lowest noise level at this station was 24.1 dB, recorded on December 1st, 2023, between 12:00 AM and 2:59 AM.

Noise levels are measured in decibels (dB), a logarithmic unit. A 10 dB increase represents a tenfold increase in sound intensity. For context, a quiet room is about 30 dB, normal conversation ranges from 50 to 60 dB, and street traffic can reach 70 to 80 dB.

For those interested in more details about noise monitoring, additional sources can be found at local environmental agencies and noise monitoring organizations.
