SW-525A Sound Level Meter Tester 30-130db Large Screen Red LCD Display Wall Hanging Type Decibel Noise Measuring with Alarm (Sound Level Meter)

This device is surprisingly well made. I've installed this in my woodshop to monitor sound levels throughout the day. Between the saws and the CNC, it can get pretty loud on the shop floor. While I use hearing protection regularly, the tester can also indicate trouble with one of the tools if the noise suddenly increases.What I like:1. The display is large and bright and can easily be read from a distance.2. It responds rapidly to sound changes. It seems to update it's reading about every second.3. It's accurate at loud sound levels. This is a place where a lot of less expensive testers don't perform.4. Mounts easily on the wall and is powered by a standard USB C connector - The cord is included.5. It has the ability to adjust internal settings based on the model you have.6. Documentation is clear and easy to follow.Things to note:1. It comes with a USB A to USB C cord, but no power supply. You will need to provide an old school USB power supply but I used an ancient Apple charger supply and it worked fine.2. There are different versions. Some will log the data (for compliance) and some have a wired alarm that can signal in another location that the sound has exceeded a threshold that you set.Would I buy again or recommend?Absolutely. It's a single purpose device, but performs well and is a welcome addition to protect my hearing.

The media could not be loaded. My professional background is in broadcasting and I taught the subject at a university.Now that I’m an old codger and retired, I hate LOUD TV COMMERCIALS. I’ve produced, shot, edited and scripted many hundreds of TV commercials and back in the “old days” we were religious about maintaining audio levels to be consistent with everything shown on TV. I use this device to validate my “grumpy old man” complaints that TV commercials are entirely to LOUD.The reason I said I didn’t want to “like this” is because I wanted to place it on top it of a cabinet near near myTV but it doesn’t come with a stand, it only WALL MOUNTS. The USB cable attaches to the right side. I was hoping it was more concealed and somehow attached directly to the backside.But these two “issues” are not a big deal because this monitor is absolutely stunning in its performance and accuracy. It quickly reports all levels for sudden burst of sound coming from the TV to quieter sounds like my wife snoring in the recliner when I turn the TV off.Take it from a “grumpy old broadcaster” you’ll be happy with this device.

The screen is very bright and clear and visible from a good distance (50 feet plus) which is what I was looking for. Also, it seems quite accurate when compared to a calibrated decibel meter. It was within 1 dB when compared. My only concern was with the update frequency of the screen. I wish the unit would give an option of response speed or averaging. The current screen picks up quick loud noises rather than smoothing out the reading, so the display is constantly bouncing around from ambient (~55dB) to 80-90 if someone coughs, sneezes, burps, etc. With this feature I would give the unit all 5 stars.

This DB meter is perfect for my live busking sessions! It is very accurate. I use it with a portable battery pack. It barely needs any battery to run. I only use about 15% of the portable battery in a 4 hours session of busking. I'm so happy with this purchase!

This DB Meter works as I expected it would. As far as it being accurate out of the box, I don't have any concerns about that. I don't have any other DB readings to compare this unit too. But I do like having it in my music room to monitor my volume. It's also great to set the volume of a backing track to match the volume of my guitar so either one won't overpower the other. I also use it to know what volume is "acceptable" so my wife can still watch TV in the other room. It's not a "random number generator". As the volume of sound it's reading fluctuates, the meter detects the changes and reacts accordingly. The manufacturer also made changes based on other reviews changing the location of the switches and plug input, making it possible to place it on a desk or surface if you so choose. It can also be hung on a wall. Now that I have it, I use it all the time.

We are systematically training our LOUD children to be more quiet! We set this on the wall and the alarm to the softest and shortest settings, with an 85 decibel threshold. After one day we significantly quieted down our home. I read reviews and expected the 2 foot cord issue, so I did go to the dollar store and bought a 6 foot cord and plug. Works great for our needs.
