Default dB Meter for a project

Gents, I need to do some measurements in the rooms for my non diy project (but together will help to balance match my speakers ).
My point is to take a "noise pollution" level in a rooms.
Would you please help me with understanding which dB meter is most suitable ?
I d like to have it fairly reliable, and if meter has memory - would be good.


Thank you

How much is in your budget? A new B&K slm would do what you want for about $5K. If you understand its limitations a Radio Shack SLM may be enough. If not you should learn a lot before you attempt real measurements because there are many factors that can cause the instrument to lie to you.

An app for a smartphone or tablet? I haven't looked, but I seem to recall seeing some pro-sound app advertised for i-things that did stuff like SPL and RTA.

I'm all in favor of managing noise in restaurants. Reducing the noise in the voice band would really help I think, although restaurateurs seem to prefer an environment where talking by sign language is the only option.

I would start with one of the smartphone apps that have a spectrum display. check on how to calibrate them and start collecting info. Read up on noise masking for offices (its closely related) noise exposure limits and all the related info. You could have a really good business.

For iPhone studiosix has probably the best apps Studio Six Digital There are a number of options for Android. get a free or cheap one and start exploring before sinking money in expensive stuff. If your not pitching something that has legal implications the Radio Shack may be enough.

I would look at the Extech meters if the Radio Shack one doesn't suit. However the phone applications are really important to understanding why the sound is or is not annoying.

Radio Shack make an inexpensive one that is very popular in the audio world for measuring frequencies in home theater. There is a lot of information on it online and also links to a piece of free software that allows analysis of the findings. Just can't recall what it is called right now. I'll try to update this when i get home.
