Review: XLNT Product - Professional $45 Decibel Meter - I needed a way to record some sounds and noise and have a "record over Time". I searched for a sound meter that RECORDS dB vs TIME STAMP....ie...REAL DATA. I FOUND it for $44 bucks. THIS unit. The SLM-25. If you are too bored, or overwhelmed at SLM-25...stop reading. IF..you are technically sound...no pun intended...KEEP reading. OK...bought the unit b/c it has "recording".....other units just give "max dB"...which is ok...but DATA is better...THIS UNIT gives Data...dB vs time...vs GRAPHICS vs....OMG how can 44 bux be SO COOL. Product: Comes with the unit...sponge top for wind...XLNT zip carrying case....USB cable... instructions (Essential) a 2-bare wire with a plug "wire"....a warranty AND the smallest compact disk you'll ever see....it's so small....like 2 inches...that you might just throw it away... DON'T....it's as much a CD DVR as anything....they just saved on plastic...and shipping width. Installation: Put the "tiny" CD into your CD/DVR reader.....the hole will fit....but you'll think it won't work b/c you've only seen CD's the size of a Bagel...get over it. Click Setup...find it if it doesn't come up...installation....Install... Click on desktop icon... Follow instructions..etc...plug unit in on USB...communication....connect.. Unit is ON when USB connected....OFF when unconnected...but can be turned on unconnected. Screen will show "real time" readouts...when connected.... Set parameters....try 20 readings at 5 seconds...gives like a minute 40 of readings... NOTE: you have to "set parameters" EACH time you record...even if you don't change parameters. Unit will say "rec" when recording...screen "recorder" counts up records...unit says "FULL" when full... You can choose as few as 20 records at one second intervals...up to a ton of records for a ton of time. Click Download for the record recorded...name it...etc.. Damn thing will come up with a "text" listing of your data vs time vs reading number... AND a professional level Line graph of your recording... You can export to Excel or to Text.....I'm using old Excel tech..old laptop...windows Vista.. so Excel was tricky...but do-able. I've routinely stacked data recordings into one Excel spreadsheet to compare "sound" conditions tests. First simple test conclusion...single test. "A Wall can block up to 20- 40 dB of Low E and High E Guitar strings"....82 Hz & 330 Hz. Minor CON drawback.....YOU NEED a Laptop THERE when you record... ie...if you hit record..and disconnect USB....no more record.... SO, you need to take unit...AND laptop to where you want to record sound. Another $41 sound analyzer "Reviewer" said he could "disconnect" after "recording start"....but I'm skeptical.....it's a minor nit...laptops have batteries and are DESIGNED to go anywhere. This product worked AS WELL and BETTER than I thought it would. I now have a "sound analyzer/recorder" for life...at the cost of $44... and cost of 4 AA batteries "whenever".... Lastly: I won't use the "exposed wire" analog item...but I won't throw it away either. - Customer Cool 10/18/19
Review: Excellent meter, just a little quirky - This is a terrific little sound level meter for the price. I works well; however, the manual is not complete. For example, I have to connect the meter to my Windows 10 PC, open the NoiseLogger Communications Tool, set the parameters, and hold down the On/Off button on the meter while I disconnect the meter from the PC. Then I can move the meter to the location where I want to measure the sound levels. If I don't hold down the On/Off button on the meter while I disconnect the meter from the PC it shuts the meter off and stops recording.

### ⭐⭐⭐⭐ Excellent tool (room for improvement)
*by M***G on November 9, 2020*

I bought this because I needed to log noise. The tool is very easy to use the software could use improvement. Also in this day and age there should be a package dowloadable via URL vs an actual CD. Lots of computers no longer have a optical drive. The other thing how is it not available for Apple Mac OS users?! The market is now at 30% Mac users and 48% Windows. I had to use my Virtual Machine to use this and worked great. The software UI is a bit complex for the average user. Overall great price.
