This works very well in my opinion and is very easy to use. It would be nice if it had a "5 second average" feature, or something along those lines. I find that you have to watch the numbers for 30 seconds or so, then mentally take an average (perhaps "note the modal value" would be better phrasing, though most people wouldn't know what it means).

What we expected

Straight forward, easy to use, lightweight, clear display, Min, Max button. Does exactly what I wanted, decibel readings ratings when setting up my hifi in the house. Good value for money. Battery included, so ready to go once you have it, pretty much.

I own both, the smaller basic meter (BAFX3370 dBA only) and the larger (BAFX3608 dBA/dBC) advanced meter.PROS1) Gets you some good data for how loud your neighbor's really are, and whether or not you should evacuate before the loudness causes hearing damage.2) Has a nicely and easily readable lit display, including light sensor for usage within dark or dimly lit areas.3) For the ADVANCED BAFX3608 dBA/dBC meter: Although Windows only, the software is made by "Sound Lab" and titled "Sound Level Meter", and is a nice simple tool, and easily comprehensible or easily utilized tool, as well as apparently being packaged without bloated software and/or software features.4) For the ADVANCED BAFX3608 dBA/dBC meter: When connected via USB ports, the device is automatically powered through the USB port.5) For the ADVANCED BAFX3608 dBA/dBC meter: If you so desire, you can stand at your window or outside your door holding this very large meter for the next door neighbors to readily see you're have issues with their noise! (I wonder if anybody also sells any flags stating a person is going to file a civil complaint?)6) For the ADVANCED BAFX3608 dBA/dBC meter: This dBC capable device performs much better than the dBA capable devices, and significantly notices the lower-frequency noise range displayed by small 4-cycle engines.CONS1) Familiarize yourself with the peak level button, else you may find you're not getting the results you desired.2) No adjustment for auto shut-off power saving feature. (ie. If you plan to leave this device for more than a few minutes, the device auto powers off.)3) For the ADVANCED BAFX3608 dBA/dBC meter, the unit does not allow the users to specify the initial on state of the readings. For example, the unit defaults to dBA and fast reading when initially turned-on. I prefer to always take readings using dBC and slow, mainly dBC as this tends to detect the lower frequency range better than dBA and selecting slow/average readings to average in anomalies versus readily seeing a distracting spiked sound anomaly. Likely when recording, the slow reading option maybe more desirable unless you're trying to monitor for very short bursts of sounds such as gun shots, and then faster readings are desired in order to capture the short bursts of sound.4) For the ADVANCED BAFX3608 dBA/dBC meter, although already heavily specified Windows Only software, such a simple device should be able to output using libUSB (and likely does so already) simple streams of data that can be easily piped into a text file for graphing by other open sourced tools. (I'll have to use WireShark to further examine the protocol used, whether serial or libUSB. USB Vendor Device ID is 64bd:74e3 "SM".)5) For the ADVANCED BAFX3608 dBA/dBC meter, the hardware manual states possible to sync the time with the computer when connected via USB, but no option appears to exist.6) For the ADVANCED BAFX3608 dBA/dBC meter, a pamphlet packaged with the device gives a download URL for downloading a copy of the software (eg. SLVersion2.exe), but this is really an old copy of the software dated 2015.10.07, and the newest version (as of this writing) is already packaged inside the box of the device, using a small mini CDROM. (The version on the mini CDROM is SoundLabSetup20160720.exe, or dated 2016.07.20)Would really be nice to have a USB feature for computer logging, or memory for logging, and easily transferring (regardless of operating system) to a computer for hard copy. (This feature is now implemented within the larger Advanced BAFX Decibel Meter.)NOTES: The ADVANCED BAFX3608 dBA/dBC meter contains a usb SILICON LABS C8051F320 8051 8-bit Microcontroller hub chip, with the firmware registering the device under Windows' Device Manager as both, a HID-COMPLIANT DEVICE and USB INPUT DEVICE. The device's USB product vendor and model USB id's are 64bd:74e3 "SM". The device contains a likely closed soure firmware, likely incorporating some minimal addressing with arguments commands to initiate retrieving recorded records, ordering the device to start sending live data, and commands for getting the current time and sending the current time. If I had more time, I would provide some C code to perform these functions, but this is tedious work versus having the specifications or already written code. The hardware manufacturer should be providing the firmware specifications (eg. PDF) for communicating to the device via ASM/C programming code. (eg. Uniden provides specifications for their firmware used on their hardware products, although sometimes difficult to find.)ATTACHED: Attaching an image comparing an apparently older basic BAFX sound decibel meter alongside the newer larger BAFX sound decibel meter.

Easy to use. Work great
