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.

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:	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

Extech Type 2 35 Decibel to 130 Decibel Digital Sound Level Meter

Whether you're monitoring workplace machinery, installing audio or alarm systems, or handling product noise certification and reduction, the Extech Digital Sound Level Meter gets the job done. This meter accurately monitors sound levels in a range from 40 to 130 decibels.

The lightweight meter easily fits in your hand and can be used wherever you need it.

Accurately Measures Sound Levels

Wherever you need to monitor sound levels, the Extech sound meter will do the job. The meter utilizes a 1/2-inch electric condenser microphone to monitor sound levels from 40 to 130 decibels at an accuracy of +/-2 dB with a 0.1 dB resolution. A windscreen is included to prevent distortion in the readings. The unit also mounts on a tripod, providing convenient hands-free readings.

The large, 2,000-count LCD display gives readings in large, clear numbers. At the same time, it shows the sound level readings using a fast-responding analog bar graph with a 50-decibel range that updates every 40 milliseconds for viewing varying trends. The unit has AC analog output and records max/min values over time.

Compact, Lightweight Design

The Extech sound meter weighs less than 6 ounces, and is designed to fit comfortably in the palm of your hand. The meter is white with a black-framed screen and black buttons.
