It is not, therefore, recommended to use this app as a high quality professional grade meter. The decibel reading obtained from this application is limited to the device microphone capabilities. Apart from that the audio or any other information is not collected, used, stored, transmitted or circulated in any way. This app is also support share readings with Messages, Email, WhatsApp, Notes and more, if the user prefer to use dB / AF values for further analysis. This app support polling functionality using web hooks to monitor the dB and frequency values for realtime data analysis. Microphone audio data is used to calculate dB (Decibels) / AF (Audio Frequency) reading to the user. This app will transform your device into a professional grade sound detector with detailed visual analysis.ĭecibel Meter app uses the built-in microphone to determine the level of sound it detects and displays it in decibels (dB). In the next few steps, we'll use this info to find the decibel level of the background noise in our studio.Track environmental noise around you with this easy-to-use decibel meter app. After setting up our equipment, we detect a background noise intensity of 1 × 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 ×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 possibleįind your sound's intensity in watts/square meter.
