Gun Club Sound level

edited April 2009 in dB
I am interested in knowing the sound level at our gun club. We shoot only shot guns and I want to measure the max dB and impulse sound levels at various locations around the grounds,  as well as be able to save the readings for future reference.

Which of the iPhone programs you offer will do this for me?

I assume I would also need an external mike for this. Can you recommend a reasonably priced one and source of it?

I don't see any mention anywhere in your program descriptions of GPS. It would be great to have this information with the sound readings, then it could be used in establishing hearing protection required zones around the grounds.




  • super_rep,

    To measure impulse sound levels (that is, with a standard impulse time weighting), SoundMeter is the app you're looking for. For now, to save your readings from within SoundMeter, you can choose to capture an image of the sound level display, take a photo upon which the sound level will be overlaid, email the sound level details, or post your readings to Twitter.

    SoundMeter does capture GPS coordinates, which can be saved/sent/posted with your sound level measurements. What level of precision do you need in the GPS readings?

    For measuring high sound levels, such as those produced by a gun at close range, you will definitely need an external microphone (dB does not support calibration of external microphones, but SoundMeter does). However, unless you have an external microphone with a very low sensitivity, you will also need to get your mic signal into the iPhone via the dock connector, rather than the headset connector. Your microphone selection will depend on several factors, including the level of precision you need in your measurements, what your budget is, how portable your setup needs to be, etc.

  • Thanks. I now have SoundMeter and it appears to be suitable. I'll know more after this weekend's session.
