[QUOTE="Ivan Beaver, post: 139975, member: 30"] Re: SPL Alarm iPad/iPhone App ? I can't help you. But consider what one of the biggest problems with that "concept" is. Most phones-even with proper external mics, simply cannot take much SPL. Around 120dB PEAK is the limit. Yes the actual "continuous" level may be 10-20dB lower-but when the input gets overloaded-the readings are off. So it depends on how accurate you want it to be. And then you have the whole A/C fast/Slow issue of what is "proper". Yes a lot of people use the A scale, but if you do a little research you will find that the A scale was never intended to be used about 80 or 85dB. So when you say it was 103dBA-what you are really saying is that I am getting some sort of reading-based on these parameters-but they don't have any relation to what the SPL might actually be or the damage that it is causing on my hearing. Yes it is a "reference", but things often get lost in what they really mean. Again-the old simple WRONG answer------------- [/QUOTE]
