I think it's a great However, I was unable to calibrate it with standard. While it might not have the highest profile equipment, for the most basic needs it's fine. I have been studying noise pollution caused by quarries in Thane district for the past few years. I was able to disqualify most of the claims that entrepreneurs made
Sound Pressure Level is the only measurement that this device can make. The display does not show frequency, and it is uncalibrated in most ways. Something else would be needed, I think.
Sound pressure level is calculated by dividing the total audio frequency spectrum by the total sound pressure level. The frequency of an audio signal is not filtered.
Neither this meter nor the other has digital outputs. The SPL is displayed in an instant, but there is also a peak hold feature. There's no way it would be useful in court. This is a purely recreational item.

SPL meters can be expensive, but this one offers a few features that cheaper ones do not. The device is capable of holding a maximum of 8 GB, has a screen backlight, and is switchable between A and C ratings. Despite not being certified in the same way as far more expensive meters, I trust this meter more than those offered at a much lower cost that are only A-rated. And I also believe this is much more accurate than any cell phone app out there. There is no information in the instructions regarding calibration if one has access to a reference meter. Although the instructions are clear enough, it does not say whether a reference meter can be used to further calibrate the device. It is one of my tools for measuring the acoustics of a room before it is treated with acoustic treatments. I use it for live audio measurement as well as for acoustic treatments in rooms. When it comes to budget - Since I am a conscientious consumer and have several Pyle products in my toolkit, I have not encountered any problems with this brand.
It had high hopes for me at first, but after using it numerous times, I gave up on it after losing hope. A sound meter app for your smartphone (and these are free) is just as accurate as this system. Especially in environments with high noise levels where a sound meter is a must, this system is terrible. Even when these environments are supposed to open up around 130dB, the air seems to be unable to register above 91dB. Pyle can't calibrate this item, so I contacted them.
Before using the unit, the instructions state that it must be calibrated, but you cannot do it yourself What are we supposed to gain by calibrating? Having instructions for a thermometer say I need to use another thermometer in order for it to accurately measure temperature is like selling a thermometer and saying use this one only in conjunction with another thermometer. Return the document as soon as possible. I also noticed that the supplied battery was no good (not a big deal, but irritating).
The 'Pink' scale should be used if only you are measuring the color If you just use noise or noise with 1000Hz, or just the sheer volume of noise, it would be fine. However, I quickly discovered that this was not a very good grade as a C- A 'weighted' precision measuring device was lacking. 1) Ability to calibrate it was not possible. 3) Once I determined the frequency, I had to record it. The display of frequency ranges is available on some devices. Several people are capable of hooking up Plug your USB into your computer. The output is not available for this one.
We discovered that this meter is consistently displaying dB levels that are higher than they are, which results in incorrect calibration of audible levels. We have been using it for over two months to calibrate surround sound rooms. It's true that the readings seem fairly consistent, so you tend to trust them, but they are grossly inaccurate, and there's no way to know without comparing to other meters in an identical The answer to this question came to me when comparing this meter's reading with those of other meters after complaints about low noise levels in calibrated rooms. I also found that the A mode of this meter matches the C mode of As a result, this meter may not meet spec in many ways. There is no way you can rely on this meter for accurate measurements.
There is a lot of jumping going on here. By using speaker levels in 5, the speaker levels are balanced. I have a two-room home theater and it jumps up and down by at least three decibels. It is not possible to get an accurate balance between Noise from the inside or outside is not present. It is better for me to use a free app for my phone.
In the first instance, the SPL meter appears like an inanimate object. In spite of this, it is an amazing device. I purchased it primarily to check the sound levels from my receiver before setting safe volume levels, but I also wanted to verify that the receiver handled the balancing of my Audissey XT properly. The Pyle SPL showed a consistent DBA rating for each of the channels at the testing site which I used to balance the stereo. We highly recommend that one learns how safe listening levels are calculated by using an SPL meter to understand what a safe listening level really is.
Sound deadening material was installed in my car before and after I used this to measure the noise levels. The tool worked well and was easy to use after a bit of practice. I don't know how accurate it is, as I got it to gauge relative distances between objects.
