A sound level meter is used for acoustic measurements. It is commonly a hand-held instrument with a microphone. The diaphragm of the microphone responds to changes in air pressure caused by sound waves. That is why the instrument is sometimes referred to as a Sound Pressure Level Meter.

The Decibel sound meter is an instrument used to measure the ambient sound level, such as sound level around factories, workshops, schools, residential, offices, road, audio and more.
It also can be appropriate for noise engineering, product quality control, health prevention and treatment, etc.

Sound level meters are most commonly used for:
• Sound level monitoring
• Addressing health issues
• Addressing safety issues
• Industrial environments
• Office environments

A sound level meter works by using a diaphragm inside the microphone that detects changes in air pressure caused by sound waves.

• Do not store or operate the instrument at high temperature and high humidity environment
• When not in use for long time, please remove the battery to avoid battery liquid leakage
• Keep microphone dry and avoid severe vibration
• Meterbox Pro software is available to download from the APP store or Google Play
