Hi,
i have question in how to choose a dB meter my specifications in nutshell
1/2 Capsule(Free Field) Microphone Capsule
A(must) ,C(optional) Freq.Weighting Type
30dB-130dB dB Range
0.1dB Resolution
30Hz-8KHz Frequency-Range
±4dB at 1KHz 94dB Accuracy
(Fast)<=200ms Response Time or Avg'g Time
Which dB meter would be perfect for measuring SPL in environment like forests here the sound level of human is measured not any animal
will my specifications match to my requirement ?
more over coming to cost :
To be frank i listened to a argument from vendor saying most of SPL are made in tiawan and other countries import them and apply their sticker on to it and sell it for high prices for example see extech SPL and same SPL from metravi which vary in cost at high level
Only SPL I know is Sound Pressure Level, and you can't apply sticker to that.

sticker in the sence i meant to say ....
most of the european companies try to get the raw product from countries like taiwan and korea and make a little decorations to that release the product with good literature
leave the sticker aside
give me some suggestions on SPL's
In deciding what PA gear to buy, the first step is to consider the type of music you play and the spaces that you play that music in. If you are an instrumental group playing in small environments—like your garage or small clubs—a minimal system may suffice. If you perform vocals, play in larger venues, or plan to tour, a more elaborate, powerful PA system will be required.
Is this thread a piece of surrealist art or what?
I think OP wants to measure sound pressure levels, or loudness, in an environments like forrest, and asks for devices which can help him acomplish that task; but devices doesn't need to be from renomed manufacturers.

Right, that's what I assumed, too, and pretty much any normal SPL meter should be OK for that.

thats what i asked, will that be ok or whether i have to take care of any parameters ?
if that is ok then its ok
If you already have a smartphone, an app might be a good choice.
Built in microphone quality should be good enough for your requirements, but it's always possible to use an external microphone.
The prices look very attractive to me
if that is ok then its ok
It's OK

To use a SPL meter in the woods a critical parameter is the lowest SPL that the device is accuate for. This varies a lot from device to device, but should be specified by the manufacturer.
The last SPL meter that I bought is an AZ corp 8928

I bought it because it is inexpensive, but you can disable its automatic power off and it will hold peaks as long as it is turned on. Some cheap SPL meters won't do either or both.
It's specs are:

A weight: 40dB~130dB
C weight: 45dB~130dB
Which are pretty good for a cheap SPL meter, some will only read down to 50 dB which is a tad high for use in the woods. I'd like to see you get a SPL meter that worked down to 30 dB SPL or better, but I think you will pay much more for that.
