Soonkoda Street,30-130dBA (30-130dBA) Digital Sound Level Meter,Sound Meter for Classroom Home dB Meter to Measure

Problem 1: DB was not detected where I needed it? Answer:This product is designed for environmental noise measurement (30-130 dB), but some users mistakenly use it for extremely low or high frequency sound sources (such as electrical micro noise, ultrasonic equipment), resulting in no readings. This is a misunderstanding of the usage scenario, not a device malfunction. Problem 2: Inaccurate/inaccurate readings? Answer:Under laboratory conditions, testing with a standard sound source calibrator (NTi Audio XL2+speaker system) showed an error range of 1.5 dB, in compliance with IEC 61672-1 Class 2 standard. The customer's claim of "inaccuracy" is mainly due to background interference, improper distance, or lack of zero calibration. Problem 3:Not suitable for the room? Answer:It is speculated that the user expects it to be used for monitoring quiet home environments (such as baby rooms, study rooms), but this model is more suitable for noise assessment in industrial, building, or public places. Problem 4:Is it not sensitive at all? Answer:The sensitivity measurement reaches 40mV/Pa @ 1kHz, and the performance of the polarizer microphone meets the standard. The so-called 'insensitivity' often occurs at a distance (>5 meters) or when the direction deviates from the main axis. Belongs to normal physical attenuation phenomenon, not a defect Problem 5:Large reading fluctuations/display jumps? Dynamic environments (such as traffic noise and intermittent machine operation) should reflect real changes; If there is abnormal jumping in a static environment, it may be caused by insufficient battery voltage or microphone moisture. The noise meter is the use of environmental sound level instrument, can be widely used in such as factories,workshops,schools,residential, office areas, traffic roads, audio and other occasions of sound level measurement.Also suitable for noise engineering, product quality control, health prevention and control.
