Great app for determining hazardous noise levels (and most of the time you don't realize the noise level is hazardous - which makes this app a must!)
I recommend that the ability to "save" the current noise level (with the ability to add a note referencing where I was at the time). Emailing a snap of the level is ok, but I really don't care to email it to myself for historical records.

Unexpected Features

The encyclopedic level of information about hearing loss and hearing protection included with this app was a pleasant surprise! Want to know about the anatomy and physiology of the ear? Feel like perusing OSHA tables on decibel levels? Need a comprehensive description of hearing protection devices? Just hit the little "i" in the bottom left corner! And this cornucopia of knowledge serves a purpose: It enables you to better interpret and understand the wealth of data the app calculates. Of course, this assumes you have some familiarity with and an appreciation of apps that almost inundate you with facts and figures, and that the process of parsing such information is in your wheelhouse. If not, you may want a more simplified app.

Useful tool for citizen action

I used this handy tool with easy-to-understand display to persuade a movie theater manager to lower assaultive sound levels of movie trailers. My awareness of hearing conditions was raised by a friend who suffers from hyperacousis. I’m now more proactive in protecting my hearing.
