• 【dB/SONE Measurement Unit】The sound level meter has two measurement units: dB and SONE. The dB unit measures the intensity of sound and is mainly used in sound engineering; the SONE unit measures the loudness of sound and is mainly used in the field of acoustics. The default unit of the sound level meter is dB when it is turned on. A short press can switch to SONE. You can choose a more appropriate measurement unit according to your needs.
• 【FAST/SLOW Response】The sound level meter has two response modes: FAST and SLOW. The FAST response is based on a 0.125s time constant and is generally used for non-steady-state and traffic noise with large fluctuations; the SLOW response is based on a 1s time constant and is generally used to measure steady-state noise. You can choose a more suitable response mode to measure according to the specific situation.
