Still, if anybody got a better solution to this. Finally offset is an offset you can add to get into the area you want. The averagePowerForChannel is the value you gain from the method averagePowerForChannel: method and range indicates the upper limit of the range. To come straight to the point: The formula you need is as follows: SPL = 20 * log10(referenceLevel * powf(10, (averagePowerForChannel/20)) * range) + offset You can also try to estimate them by comparing your results with an app like decibel Ultra. Check it out Decibel X: dB, dBA Noise Meter.

In other words you need a DB SPL values and the according voltage values to them. So hereвЂ™s the list of 11 best decibel meter apps that are available for Android & iOS users.

We need to convert that output in decibel SPL which is not so easy because for that you need reference values. The decibel SPL is a logarithmic unit that indicates ratio. I think what both of us want to achieve is the decibel SPL but the averagePowerChannel method gives us the mic's output voltage. SPL Meter iOS SPL Meter is a professional-grade sound level meter, also known as a decibel or dB meter, for your iPhone. I figured out a better solution (correct me if I am wrong). The thing isn't that it has a shitty mic, is that its shitty mic is consistent. They tested it against fairly expensive spl meters and it came up incredibly similar. Can't recall the name but other comments have suggestions. In the next few steps, we'll use this info to find the decibel level of the background noise in our studio.Forget my previous answer. iPhone decibel meter apps are ace, years ago I did a bunch of research and this one smaller one had the most accurate rating.

After setting up our equipment, we detect a background noise intensity of 1 Г— 10 -11 (0.00000000001) watts/square meter.

For the purposes of this problem, let's say that we're music producers and we're trying to find the background noise level in our recording studio to improve the sound of our records.

To better understand the relationship between intensity measurements and decibels, let's follow along with an example problem.

For instance, a sound with an intensity of 5 Г—10 -5 (or 0.00005) watts/square meter translates to about 80 decibels - about the volume of a blender or food processor.

Note that, for ordinary sounds, the intensity value is usually very small.

X Research source Because of this direct relationship between a sound wave intensity and its volume in decibels, it's possible to find a decibel value given nothing more than an intensity level for the sound (which is typically measured in watts/square meter) The larger the amplitude of a given sound wave, the more energy it transmits, the more it moves the air particles in its path, and the more 'intense' the sound is. In physics, decibels are often thought of as a convenient way of expressing the intensity of a sound wave. However, the truth is a little more complex. For everyday practical purposes, decibels are usually seen as a simple measure of loudness. Immediate hearing loss or eardrum rupture possibleДЇind your sound's intensity in watts/square meter. May be immediately painful damage after lengthy exposure very likely Serious damage likely after lengthy exposure Likely hearing damage after lengthy exposure Lawn mower, motorcycle at 25 feet (7.62 meters) Possible hearing damage after lengthy exposure It has several features that can measure the intensity of surrounding noises. ItвЂ™s standard measurement ranges between 30 to 130 dB.

The NIOSH Sound Level Meter app has many important features, it provides a readout of the sound level using the built-in microphone (or external microphone if used) and reports the instantaneous sound level in A, C, or Z-weighted decibels. Relaxed conversation, ordinary suburban activityД«usy office or restaurant noise, loud conversation
