sound level meter Product Introduction: Aihua's noise meter belongs to a level 2 sound level meter, used for general noise measurement, and does not require range conversion during use.

Scope of application: It is applicable to environmental protection, labor health, industrial enterprises, scientific research and teaching fields. It is used for environmental noise measurement, machinery and equipment noise measurement, airport noise measurement, sound power level measurement and architectural acoustics measurement.

Measurement method:
1. When measuring, the instrument should choose the correct gear according to the situation, hold both sides of the noise meter flat with both hands, and point the microphone towards the measured sound source. Extension cables and rods can also be used to reduce the impact of the noise meter appearance and human body on the measurement.
2. Select a representative testing location, with the sound level meter off the ground and off the wall to reduce the additional impact of reflected sound from the ground and wall.

Unit of measurement:
1. A sound level, denoted as dB (A): simulates the frequency characteristics of low intensity noise below 55dB in the human ear (the most widely used type)
2. B sound level, denoted as dB (B): simulates the frequency characteristics of moderate intensity noise from 55dB to 85dB
3. C sound level, denoted as dB (C): simulates the frequency characteristics of high intensity noise
