This audio digital sound level meter has an operating temperature of 0 to 40 degrees Celsius and operating humidity of 10% to 70% RH. It works on 9 Volts Alkaline cells and has an integrated 0.5 inches condenser microphone. It has a full measurement range of 40~130 dB (decibel) and produces an Sound intensity is the amount of sound energy in a confined space. It is measured in decibels (dB). The decibel scale is logarithmic, which means that loudness is not directly proportional to sound intensity.

where, W = sound power in watts of a given source; W 0 = reference sound power ‎"Decibel X" is one of very few noise meter apps on the market that has highly reliable, pre-calibrated measurements and supports dBA, dBC. It turns your iOS device into a professional sound level meter, precisely measures the sound pressure level (SPL) all around you. This extremely useful and beaut… Decibel Meter application uses the built-in microphone to determine the level of sound it detects, and displays this in decibels (dB) as max, average and peak sound pressure level. At those sound levels at near field measurement, 130+ decibels (dbA) A-weighting is the threshold of ear pain or ear ringing, and that is louder than most 15 The decibel is defined as one tenth of a bel where one bel represents a difference in level between two intensities I 1, I 0 where one is ten times greater than the other.
