Noise Pollution Parameters
This page explains the various parameters collected for noise pollution monitoring. Understanding these parameters is key to interpreting the data correctly.
Unit: dB(A)
The average sound energy over a period, converting fluctuating noise into a steady level for assessing long-term exposure.
Unit: dB(A)
Captures the peak noise level, vital for identifying short, loud noise events like car horns or door slams.
Unit: dB(A)
The lowest sound level recorded, helping to establish a baseline noise floor for comparison.
Unit: dB(A)
The noise level exceeded for 10% of the time, often used to describe traffic noise and intrusive events.
Unit: dB(A)
The noise level exceeded for 90% of the time, representing the ambient or background noise of a location.
Unit: Hertz (Hz)
The pitch of a sound, important for identifying its source and designing effective noise control measures.
