A sound level calibrator is a precision acoustic device used to verify and adjust the accuracy of a sound level meter. It generates a known, stable sound pressure level, 94 dB or 114 dB. An acoustic calibrator is essential in applications where accuracy is critical, such as environmental noise monitoring, industrial noise surveys, and laboratory testing.
Backlit Display
- Improved Visibility in Low-Light Environments. A backlit display ensures clear readability in dim or dark conditions, such as industrial plants, outdoor night measurements, or soundproof rooms. Users can easily read calibration values without relying on external lighting, reducing eye strain and improving operational efficiency.
- Enhanced User Convenience. Digital sound level calibrator with a backlit digital screen, users can perform calibrations quickly without adjusting their position, flashlight, or surrounding light. This convenience is valuable during fieldwork, routine inspections, or time-sensitive calibration tasks.
Lightweight Sound Level Calibrator
- User-Friendly Interface. The lightweight digital acoustic calibrator features intuitive digital display and buttons. This reduces the risk of user error.
- Convenience for Field Work. Field engineers, acoustic consultants, and environmental professionals often work in outdoor or industrial settings where carrying heavy equipment can be cumbersome. A lightweight sound level meter calibrator ensures that they can quickly and efficiently perform calibrations on the go.

Structure:
Q1: What is a sound level calibrator?
A1: A sound level meter calibrator is a precision device used to verify and adjust the accuracy of sound measuring instruments, such as sound level meters. It generates a stable, known sound pressure level, usually at a specific frequency, commonly 94 dB or 114 dB, allowing the meter to be calibrated before measurements.
Q2: How does temperature affect the calibrator's performance?
A2: The performance of a sound level meter calibrator can be affected by temperature changes. The operating temperature of this acoustic calibrator is -10 ℃ to 50 ℃. Extreme temperatures outside this range may cause drift in the output sound pressure level, affecting calibration accuracy. To ensure reliable calibration, it is recommended to allow the calibrator to stabilize at the ambient temperature before use and avoid exposing it to sudden temperature changes.
Q3: How should the sound level calibrator be stored when not in use?
A3: When not in use, a noise meter calibrator should be stored in a clean, dry, and stable environment to ensure its accuracy and longevity. Keep it in its protective case to prevent dust, moisture, and mechanical damage. Avoid exposing it to extreme temperatures, direct sunlight, or high humidity, as these conditions can affect its calibration. Store it away from strong magnetic fields or vibrations.
Tips: Can sound level calibrator be used for environmental noise monitoring?
A sound level calibrator is primarily designed to verify and calibrate sound level meters, ensuring their measurements are accurate. It produces a precise reference sound, usually at 94 dB or 114 dB, for calibration purposes. While it is essential for maintaining measurement accuracy, it cannot measure environmental noise by itself, as it does not capture sound from the surroundings. For environmental noise monitoring, a calibrated sound level meter is required, with the calibrator used beforehand to ensure reliable readings.
