Tips: Types of sound level meters

According to the sensitivity of the whole sound level meter, there are two types of sound level meter classification: one is the ordinary sound level meter, which does not require much microphone. The dynamic range and frequency response flat range are relatively narrow, and bandpass filters are generally not used in combination; the other type is precision sound level meters, whose microphones require wide frequency response, high sensitivity, and good long-term stability. This kind of band-pass filter is used together, the output of the amplifier can be directly connected with the level recorder and tape recorder, and the noise signal can be displayed or stored. If the microphone of the precision sound level meter is removed, replaced with an input converter and connected to an accelerometer, it becomes a vibrometer that can be used for vibration measurement.

How accurate is it? Can one rely on the readings?

How accurate is it? Can one rely on the readings? Could I set this outside and have it record sound levels overnight 6-8 hours and it would capture sound readings over that time?

We promise it is accurate enough. The item could be capture the MAX or MIN sound level overnight 6-8 hours,but can't record all dynamic data.
