I have been working with an earplug company to develop a product
specifically for piano tuners, and have been compiling data as well
as testing various premium sets. One thing I have found out is that
many cell phone manufacturers set a decibel cap at 90dB. So getting
an app may only be good up to that level. They also need to be
calibrated and when installed may have significant deviation.
I have one of the analog Radio Shack meters, and they are good,
but it is hard to track what's being detected without a digital tracker.
I also have an Agfa unit that is nearly equal to the RS and it keeps
track of what the highest readings are. So far I have found peaks
at around 123dB. 85 is considered harmful. Spinets, consoles and
petite grands read surprisingly high.

Greetings,
I have a hand held decibel meter that I would like to give away if someone is interested. I bought it at Radio Shack a few years ago, The price was in the neighborhood of $25.
If anyone wants it I can send it to you for the price of shipping. Its' small so the cost of shipping would be low.
