Review: A nice cheap sound level meter with only minor flaws - 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 when reading but that difference is probably caused by the averaging cycles on two independent meters not having synchronized clocks. Months later that difference did worry me enough that I bought a SPL meter calibrator and found that both this and the other SPL meter I bought are within about 0.2dB of the calibrator specifications using 1kHz at 94dB and 114dB. That's a lot better than this meter's documented accuracy of +/- 1.5dB (that probably is for the whole audio band used rather than specific to a 1kHz tone). However, the calibrator made me confident that this is usable out of the box as a valid SPL meter for me. In testing without a calibrator using the following in-room sounds this meter and the other meter I bought the readings vary within 1dB to 2dB of each other: Ambient sound level Music at a pleasant volume White noise a 10 second 30Hz to 8kHz sweep (covering the documented frequency response) Testing with tone generator at 1kHz that is not the calibrator I bought I also see deltas close enough to 3dB when halving or doubling the output amplitude. Testing with an Android audio signal generator app via a bluetooth speaker that has dedicated filtering for music. Using a 1kHz tone and halving or doubling the amplitude I see a delta on the meter close enough to +/-3dB. Since both meters have a stated accuracy of +/-1.5dB with 0.1dB resolution I'm comfortable with readings from 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. However, C Weighting passes low-frequency sound below 1kHz that is heavily filteres using A Weigting. So, although the differnce between this and the other meter I bought is pretty severe using C Weighting (typically 4x linear power difference and up to 10x linear power difference between the two meters) I don't think it is representative since I'm not in an environment with significant low frequency noise. I wasn't using sources with high audio power levels, just the same ones as I tested the A weighting with and they may even contribute to the difference I saw between the meters if the audio sources are optimized for human hearing. Of the two meters I bought I suspect from my observations that this model is the more accurate in the C weighting mode so trust this purchase more, but only slightly so. Having used a calibrated signal source and non-calibrated signal sources my observations are that this is delivered as a pre-calibrated, ready to use SPL meter with very good accuracy at 1kHz and decent low frequency accuracy. The live level meter is quite nice, my other meter has a bar meter with lots of bars but is only actually capable of displaying three levels as a stepped scale whereas the bar meter on this is a continuous scale. It would be nicer if I could have the fast/slow display modes apply independently on the bar meter and the numeric dB reading, I'd like a fast bar meter but a slow numeric meter. The fast update mode is 8 times per-second for the displayed dB level on the LCD and is probably great for tuning a stable signal but I have to say I prefer the slow mode with an update per-second due to the less volatile and easier to follow meter number. It's nice that it has a min and max view giving a nicer perspective than my other device which only has a max view. 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. The LCD display is monochrome on this and color on my other meter but there's not a lot of use for color on a sound meter, other than perhaps the bar meter progressing towards red at high levels which this meter can't do, I prefer the microphone pop filter on my other meter over this where it's quite thin but both meters have the same size (1/2 inch) microphone protrusion I can swap the pop filters over when in use meaning the thinner one on this doesn't matter much to me The meter does quite a good job of filtering out user handling noise but not nearby ambient noise like moving or placing things close to it. It has a nice solid cover for the microphone and pop filter when unused but it always removes the pop filter when I take the cover off, leaving the filter inside the cover. It also has a temperature and humidity display. Thermometer seems accurate enough displaying Fahrenheit but the hygrometer looks like it under-reads others I have at home by 10% and I suspect the hygrometer on this has the error. On the whole I'm happy using it to monitor and compare sound sources I experience.
Review: Large unit, large screen, simple to use. - Larger than the competitions model. This is helpful because it has a larger screen which is easy to read. Backlit screen is nice, function buttons are clearly marked and raised. Includes 3 AAA batteries, major name brand and not the cheap low life kind. Also included is a soft carry bag for the unit, unfortunately the owners manual can’t be kept in the bag. Owners manual is clearly written, detailed with drawings, written in 6 languages, has QR codes for each language. Only one gripe; there is a large cap cover for the microphone that when removed, where can you put it? Won’t fit on the base, have to put it in your pocket. Also it would be nice to have a color coded card that gives you warnings about decibel levels, safe to dangerous, that can fit in the included case. Otherwise, a good unit.

## Questions & Answers

**Q: Why doesn’t the TS-501B show 0 dB in a quiet environment?**
A: The TS-501B measures from 30–130 dB and does not start at 0 dB. When sound levels are below 30 dB, it displays “UL” (Under Limit). In a quiet environment, it reads between 30 and 45 dB.

**Q: What scenarios are sound level meters usually used for?**
A: Sound level meters are often used for measuring community or environmental noise; Use for measuring noise produced by machinery in industries; Use for calibrating audio equipment at concerts or for personal reasons.

**Q: What is the difference between A Frequency Weighting and C Frequency Weighting?**
A: The A-weighting adjusts the sound pressure level readings to reflect the sensitivity of the human ear and is used for hearing damage risk measurements. The C-Weighting is used for Peak measurements and also in some entertainment noise measurements.

**Q: What is the difference MAX/MIN Value between A-Weighting and C-Weighting?**
A: MAX/MIN Value of A-Weighting is Lmax/Lmin (the highest and lowest values measured by the sound level meter over a given period of time.); MAX/MIN Value of C-Weighting is Lpeak (the max/min value of the absolute instantaneous sound pressure).

**Q: Decibel Levels: Typical Scenarios**
A: 30-40 dB: Library, bedroom. 50-60 dB: Restaurant, café. 70-80 dB: City roads, factory machinery. 90-100 dB: Rock concert. 110-130 dB: Jet airplanes, front row at a concert.

### ⭐⭐⭐⭐ Pretty good Decibel meter. Not rechargeable.
*by B***R on January 31, 2026*

This decibel reader seems to work well. Build quality is pretty decent. Large backlit screen is easy to see. It appears to offer accurate decibel reading. I like having this to measure generator noise levels. One improvement that could have been made is to make this rechargeable. But other then that, no real complaints...
