Outdoor Sound Level Meter
Outdoor sound level meter is a specialized device used to measure the sound levels in outdoor environments. It is designed to capture and quantify the ambient noise or sound pressure level (SPL) present in the outdoor surroundings. These meters are commonly used for environmental noise monitoring, noise pollution assessment, city planning, and industrial noise control purposes.
Outdoor sound level meters are valuable tools for assessing noise pollution in urban areas, near highways or airports, construction sites, and industrial facilities. By gathering accurate data on outdoor sound levels, city planners, environmental agencies, and noise control experts can make informed decisions to mitigate noise-related issues and promote a healthier living environment.

- Microphone: The meter is equipped with a high-quality microphone that picks up sound waves in the surrounding environment. The microphone's sensitivity and frequency response are carefully calibrated to accurately capture the full range of outdoor sounds.
- Measurement Range: Outdoor sound level meters typically have a wide measurement range, covering a broad spectrum of sound levels, from very low ambient noise to very loud sounds, such as traffic, construction, or industrial noise.
- A-Weighting: To mimic the human ear's sensitivity to different frequencies, outdoor sound level meters often use A-weighting filters. A-weighting emphasizes frequencies in the range where the human ear is most sensitive and is commonly used for environmental noise assessments.
- Data Logging: Many advanced outdoor sound level meters have data logging capabilities, allowing them to continuously record sound levels over time. This is particularly useful for conducting long-term noise monitoring studies or evaluating noise patterns throughout different times of the day or week.
- Real-time Display: The sound level meter usually has a real-time display that shows the current sound level in decibels (dB). Some models may also display additional metrics, such as maximum sound level (Lmax), minimum sound level (Lmin), and average sound level (Lavg) over a specified period.
- Weatherproofing: Since outdoor conditions can be harsh, outdoor sound level meters are often built with weatherproof and ruggedized designs to protect them from rain, dust, and other environmental factors.
