User questions & answers

Question:	noisy neighbor issue. Could I set this outside and have it record sound levels overnight 6-8 hours and it would capture sound readings over that time
Answer:	Dear Customer, The item could be capture the MAX or MIN sound level overnight 6-8 hours,but can't record all dynamic data.
Question:	Does this have c weighting and slow response options ( for calibrating monitors
Answer:	Yes it has C weight and fast and slow
Question:	My neighbor is a tire company there business is fenced off, they use compressed air all day, will this pick up the decibels at approx 300 feet away
Answer:	It will read the ambient sound level, and the compressor will be part of that. It shouldn't matter what the sound is at 300 ft. Get a copy of your town's noise ordinance; work with the cops, if that is not satisfactory, lawyer up.
Question:	How accurate is it? Can one rely on the readings
Answer:	The one I have seems pretty accurate, comparing the readings to a minidsp umik-1 they are very close. Assuming the umik-1 is calibrated correctly I would say decently accurate.

User questions & answers

Question:	Which Windows operating systems is this software compatible with
Answer:	I have never been able to get the software to work under Windows 10 Pro. It never recognizes the device. I spent many hours trying to get it to work. I tried to get it working on my 8 core desktop, a Microsoft Surface Book, and a Surface Book 2 when I upgraded. I also emailed back and forth with support several times. They tried their best to help, but none of their suggestions worked, so I finally gave up on using the Windows software with this device. It's a shame because the PC connection is one of the reasons I chose this device over other brands. Of course, by the time I gave up, it was well past the return period. Fortunately, as a stand-alone device, this meter works very well. So, even without the PC software, it's a great value. In fact, despite the software issues, I'm still pretty happy with this meter. I hope this was helpful.
Question:	Are these calibrated before they are shipped
Answer:	According to directions it is well calibrated before shipment and recommends recalibration cycle of one year. Directions tell you how to recalibrate. Seems to be working for me/
Question:	Does this show average volume? Concerned that the readout will change too quickly to log the general reading
Answer:	Hi there - I am with BAFX Products Support.The previous answer is correct. There are two modes. The first mode simply reads the noise level at a constant rate, continually flucuating as the noise level changes. The other mode as she mentioned is the "MAX" mode. When you set it to this mode it will hold the highest reach noise level since placing the meter on MAX mode. There is not a mode that will give you an "average" reading for a period of time.If you have further questions, please do not hesitate to contact us.Regards,BAFX Products Support
Question:	Will this meter really go down to 30dBm? I bought one that said it would but when I got it it only went down to
Answer:	Hi there - I am with BAFX Products Support.It can certainly reach 30dBa however to find a location where the sound level is that low you will need to work very hard. Even most "VERY quiet rooms" are going to have a readings of anywhere from 35-45dba.Using it in a room of a house away from any busy streets, with all windows and doors closed, all ventilation off and all air ducts closed and no humans or animals in the room, MAY allow you to get down to 35dBa or so. Reaching a level of 30dba is going to be extremely difficult for most people unless you have a sound proof room.Regards,BAFX Products Support

Compact, Easy to use, Easy to read & Great for general purpose measurements

The BAFX Products Decibel Meter has the quality and features you require at a fraction of the price!

Our Decibel Meter (also known as a "sound pressure level meter") is compact and easy to use while providing you accurate readings in a greater range than similar inexpensive sound meters on the market! Our sound meter can read between 30dBA~130dBa, while reducing the effects of wind noise to produce more accurate readings. The BAFX Products sound meter provides readings within +/-1.5dBA providing some of the most accurate results!

Perfect for monitoring noise levels in factories, offices, theaters and audio systems.

The meter will automatically power off after approximately 11 minutes of use (auto off can be disabled) and MAX / MIN Hold Function will hold the highest / lowest reading until a higher or lower reading is picked up.



Included with the Decibel Meter is one, 9V Battery to start you off which will provide you about 30 hours of use.

Other great feature are: Sampling rate of 2X/second, Automatic back light display, Low battery indication, Frequency response range of 31.5Hz ~ 8.5KHz

PLEASE keep in mind that this meter measures in dBA to account for the relative loudness perceived by the human ear. This is the most commonly used dB measuring frequency. "A" weighted decibel measuring means that values of sounds at lower frequencies are reduced.

Noisy neighbors

Noisy neighbors throwing parties at all hours giving you headaches but not sure if they are violating local code making it worthwhile to call the police? Our decibel meter can help! Find your local ordinances on noise levels for measuring guidelines, and measure your neighbors noise level using the local code to determine if the police should be called.



Please note though, our meters are not NIST certified meaning that their readings cannot be used in a court of law. Your local police should have NIST certified meters for this if things escalate to that point. NIST certification is very expensive and our goal is to provide a meter for everyday people at reasonable prices.



Don't waste your local police resources with frivolous calls, know your neighbors are in violation of the local code before calling!

User questions & answers

Question:	Does this meter do dbC weighting in addition to dbA
Answer:	The instruction booklet describes only “A” weighting. There is no reference to dbC mentioned.
Question:	what does weighing a+unit mean? what is a triangle bracket? thanks
Answer:	triangle bracket is I believe is referring to a tripod like for a camera ,
Question:	what about its warranty
Answer:	From the warranty card included in the box: Within 30 days - return for full refund; 30-90 days - will replace defective unit with a new one; 90 days to 6 months - Will replace unit with new one. If registered on tacklifetools.com - receive extra 3 months warranty. Contact [email protected] for RMA #.
Question:	Where is this product made
Answer:	"Made In China" ... that is what is molded on the 9v battery door. Not sure why that really matters as it seems that 80% of the world's products come from China. If we were a bit more tyrannical, empirical, communistic methods then maybe we could compete but who wants to make products where we poison the community, the workers and their minds. I remember where things were "Made in the USA" and if it came from another country it was like "wow!" really? Back in the 60's, anything German and Japanese had a great reputation ... so where where we? oh yes ... I have one and it works and its cheap and its made in China. I hope this helps

User questions & answers

Question:	I have a very busy neighborhood road with noisy traffic. i need to be able to record over a period of time, maybe 12 hours. any suggestions
Answer:	It would work. Just set the interval for like every 15 minutes for 24 hours, it will save it onto an XL spreadsheet. I'm not sure about 12 hours though, you have to see how long it will stay on before turning off automatically
Question:	we need to monitor 8 hours in a production plant is this unit capable
Answer:	We use this sound meter for accurate spot measurements in different locations. I believe this can be connected to a computer to log data, but we have not tried that, and a simple dosimeter/datalogger that is standalone is in my opinion much more convenient for continuous monitoring purposes.
Question:	What is the frequency response for this unit? +/- 1.4 dB between what frequency range
Answer:	The +/- is good for the range of the weighting curve, A or C you are on. Check the web for SPL weighting curves for more detail.
Question:	what is the frequency range
Answer:	Hello, the frequency range is 20 Hz to 8 kHz .

User questions & answers

Question:	How well will this work to measure the sound level in a car cabin
Answer:	IT can work fine. When turned “on” it displays an internal reading that appears high. Ignore this reading because the car read is probably higher.
Question:	Can you program this to beep or alarm at a certain noise level
Answer:	no you can not program it at all. it just has the microphone on top to pick the noise up and then shows you on the display what the noise level is.
Question:	Does it lock to the loudest sound? , if I wanted to check the db of a gunshot for example
Answer:	I'm not sure what you mean "lock" but you can check for the loudest db very easily, and the lowest db, too. It doesn't stay on that number forever though. Or at least I haven't gotten it to do that. But I'm usually too busy trying to figure out the average db's. I wish it told me that. It cycles off after so long (maybe 20 - 30 min.) and then you've lost all the data.
Question:	can this record noise over a certain period of time
Answer:	No, this does not record, just measures the decibels of the noise

User questions & answers

Question:	Is it normal for the device to measure 47 dBA in a quite room out of the box
Answer:	47 seems a bit high, but listen to what is around you. There may be things that you've grown accustom to and therefore 'tune them out'. If you have a large closet with a fair amount of hanging clothes (they absorb a lot of noise), try it in there. In my case I get 38-40. Also, holding it can make a difference. What do you get if you put it on a tripod? I had an opportunity to compare mine to a pro-quality unit (> $2,500) in a sound room, but didn't think about it at the time given the rush to get things done.
Question:	Why is it Not calibrated at factory
Answer:	Dear Our products are calibrated with standard sound sources before leaving the factory, because in a quiet environment it does not mean no sound. You can rest assured that our products are professionally tested and calibrated. Please feel free to purchase and use.
Question:	Would this be good at measuring sound spikes or just ambient noise? For example trying to measure a gun shot at the range
Answer:	Yes. It can be set to track the highest sound and hold that measure so you can review it.
Question:	Do these meters conform to ansi si
Answer:	Unfortunately I am not able. The product information is very vague but then again it was very in-expensive. I'm using it for general measurements. If you're looking to meet ANSI then I suggest you spend the money and buy an appropriate product from a more scientific company. No slam on Meterk but they appear to sell a wide variety of products. You may wish to consider Amprobe SM-10 at $172 as it seems to meet ANSI, IEC, JISC (Japan) and N10140 (Australian) standards

Answer:	yes you would need another tool to measure feet
Question:	Does it come with the tripod
Answer:	No, it doesn’t.
Question:	In the description photo I see a reading of 31.9. My meter never ever under the most quiet moment on earth will go under 36.7. Is your meter similar
Answer:	the lowest reading I got is 35dba and this is accurate enough for my use. I needed it for measurements at 80 to 100 dba. I can not guarantee that my roos is absolutely quite or at 30dba. Maybe the $388 unit will do better and be more accurate. The $20 unit did just fine for me. Now is sitting lonely in the corner hopping for more use.

User questions & answers

Question:	Anyone have a manual in English
Answer:	No.
Question:	Does this device allow for a data download onto a computer
Answer:	525A does not support, 525B supports data synchronization to the computer,
Question:	Can you set the high level you want the alarm to sound
Answer:	Yes you can. FYI - This worked ok as a fast curve but I needed a slow curve so I sent it back.
Question:	Will an alarm go off if a certain sound level is reached? Need this feature for my son
Answer:	There is an alarm feature but it is not very loud to hear it if the unit is setup more than 5ft away. When a level is set the numbers will blink/flash for about 10secs to notify you that dB level has been exceeded which i like better than an alarm. Hope this helps.
