Metravi Sound Level Meter, SL

The Metravi Sound Level Meter (SL) is a device used for measuring sound pressure levels in various environments. Here are the key features and functions of the Metravi Sound Level Meter: Measurement Range: The SL meter is capable of measuring sound pressure levels over a wide range, typically expressed in decibels (dB). The range may vary depending on the specific model but commonly covers levels from around 30 dB to 130 dB or higher. Microphone: The meter is equipped with a microphone that captures sound waves and converts them into electrical signals for measurement. The microphone is typically built into the body of the meter and may have specific characteristics to ensure accurate sound measurement. A-weighted Filter: Sound level meters often include an A-weighted filter to mimic the human ear's response to different frequencies. This filter is commonly used for measuring environmental noise levels and compliance with noise regulations. Fast and Slow Response: Sound level meters may offer both fast and slow response settings. The fast response setting provides real-time measurements, while the slow response setting averages the sound levels over a longer period, providing a more stable reading. LCD Display: The SL meter features an LCD display that shows the measured sound pressure level in decibels. The display may also indicate other parameters such as the measurement mode, frequency weighting, and response time.
