## Features

- 【High Accuracy】Mastfuyi decibel meter uses a precise condenser microphone to capture sound, measures sound level 30-130 dBA, 35-130dBC. Highly accurate with ±1.5 dB, Frequency from 30Hz to 8,000KHz, Perfect for monitoring noise levels in community, home, audio system, automobile, school, office, factory
- 【A/C Weighted Measurement】When measuring the sound level felt by human beings, select A-Weighting mode which simulates the frequency of low-intensity human ear noise; when measuring the actual sound level like noise analysis of machine motors and machines, select C-Weighting mode which simulates the frequency of high-intensity noises of the human ear. Professional measurement methods provide users with a perfect experience
- 【Compact and Lightweight】Composite material injection molding process and ergonomic design, non-slip and wear-resistant, comfortable to hold; Slim and lightweight, doesn't take up space, easy to carry and store; Pocket clip design allows it to be securely clipped to the pocket and not easily dropped and lost
- 【Fast/Slow Measurement】The Fast-Weighting mode uses a constant of 0.125s/time, which is suitable for measuring the sound level in real time in general environment; The Slow-Weighting mode uses a 1s/time constant, which is suitable for environmental measurements with relatively large changes in noise levels
- 【Versatile Uses】Features a full color LCD screen with a resolution of 0.1 dB, clear and beautiful; MAX hold function to lock the maximum value; Auto power off after 15 minutes inactivity to prolong battery lifespan; Data Hold function to freeze the current readout, easy to read and record data; Flashlight for use at night
- 【Dual Visual Alerts】Level 1 (90dB): 🟩🟨🟥 analog bars is displayed, 🔴 indicator lights up, need to leave the sound source as soon as possible
- 【Calibration】Before calibrating the instrument you need to prepare a standard sound source device to be used for calibration, please do not calibrate without a standard sound source device. The A-weighted calibration steps are as follows: Step 1: Press SLOW/FAST button, Flashlight/HOLD button and power switch button at the same time and then release the buttons to enter the calibration mode. Step 2: Set the standard source device to 94dB, then align the meter to the standard source device, wait for the meter reading to stabilize at 94dB, press the SLOW/FAST button to save, and then press the power switch button to restart the device that the calibration is complete.
- The C-weighted calibration steps are as follows: Step 1: Press SLOW/FAST button, Flashlight/HOLD button and power switch button at the same time and then release the buttons to enter the calibration mode. Step 2: Press the A/C button to switch to C-weighted. Step 3: Set the standard source device to 94dB, then align the meter to the standard source device, wait for the meter reading to stabilize at 94dB, press the SLOW/FAST button to save, and then press the power switch button to restart the device that the calibration is complete.
- 【NOTE】The flashlight can only be used properly when the noise is higher than 50 dB; Turning the flashlight on and off may affect the data hold function
- 【48-Month Warranty】We provide 48 months unconditional warranty and lifetime after-sales service

## Customer Reviews

### ⭐⭐⭐⭐⭐ To test my AVR and speaker.
*by T***D on December 19, 2024*

Works awesome and love it.

### ⭐⭐⭐⭐ You'd need a calibrated source to be sure but it seems to do a decent job
*by D***R on January 31, 2025*

I bought two different brand/models of sound meter. Since they can be found so cheap it was worth getting a second to compare results. In a room with a background reading of just under 40dB, using the slow update rate, both using the A weighting, this meter is typically within about 1 or 2dB of the other meter:Ambient sound levelMusic at a pleasant volumeWhite noisea 10 second 30Hz to 8kHz sweep (covering the documented frequency response)Testing with a tone generator at 1kHz I also see deltas close enough to 3dB when halving or doubling the output amplitude. The sources aren't calibrated, an Android audio signal generator app via a bluetooth speaker that has dedicated filtering for music.However, since both meters have a stated accuracy of +/-1.5dB with 0.1dB resolution I'm comfortable with the A weighting mode on this device.In the C weighting mode the reading from the two meters differ typically by around 6dB using the same sources and peak difference is about 10dB. That is pretty severe (typically 4x linear difference and up to 10x linear difference between the two meters using C weighting). I wasn't using sources with high audio power, just the same ones as I tested the A weighting with. Of the two meters I bought I suspect this model the less accurate in the C weighting mode and typically over-reads the real audio power level.Without a calibrated signal source these observations are only illustrative speculation rather than verification of anything.The live level meter is really just a stepped scale with three levels, green, yellow and red shown on a horizontal bar with six segments for each color and the expected purposes for the colors. It would be nicer if each individual bar segment was used individually to implement a live meter view. Above 50dB a rather annoying set of 3 yellow/greed LEDs is lit on the left of the LCD display, it makes sense if the level is persistently above 50dB for hours according to government data but probably not significant in a case like music that just exceeds 50dB repeatedly and flashes the LEDs. Above 90dB a set of 4 red LEDs lights on the opposite side of the LCD display. In both cases the LEDs are quite distracting from the meter reading.The fast update mode is 8 times per-second for the displayed dB level on the LCD and is probably great for adjusting a source of a stable signal but I have to say I prefer the slow mode with an update per-second due to the less volatile and eassier to read meter number. This is a place where a true bar meter updating 8 times per-scond while the dB level number updating every second would be quite useful.It's a shame it can only show the maximum sound levels, my other meter has a min and max view which is a nicer perspective. Both have a button to hold the currently displayed level which can be helpful trying to judge the effective level at some point when using the high speed update rate.It comes with what seems to me like a nice microphone pop filter that seems to me to be better than the one supplied with the other sound meter I bought. It has a belt clip and the battery cover has a screw to secure it. It's does quite a good job of filtering out user handling noise. But is easily distracted by simple sounds like moving things near it.It's a shame there is no cover for the microphone other than the pop filter, when unused for long periods the pop filter will take any bumps.On the whole I'm quite happy using it to compare sound sources, particularly using the A weighting. The not 5 star is only because of things like the coarseness of the bar level meter, the high (yellow/green) and severe (red) level LED indicators being so bright and close to the LCD view.

### ⭐⭐⭐⭐⭐ Good quality, worked as listed
*by T***B on July 24, 2024*

Easy to use and perfect for balancing my 9.2 multi channel sound system
