This soundmeter App is the only one for iOS recommended by the "Laborers' Health and Safety Fund of North America". The Sound Pressure Level ( SPL) is the most basic level used in sound measurements. The SPL, measured in Decibels (dB), has been widely used since the 1930s. SPL is defined as the logarithm of the ratio of the sound pressure to a reference pressure. SPL = 20 log10(p/pref) dB. p → the instantaneous sound pressure in Pa. Determining the sound level is simple: set the meter’s dial on a number, such as 70. When the dial is set to 70, the needle is displaying sound pressure measurement relative to 70. When the needle hits the middle 0 position, the SPL of the sound you’re measuring is 70dB. If it reads -4, that means it is 4 under 70, or 66dB.Sound Level Meters measure very small changes in pressure. The microphone and measurement chain may drift due to temperature stress and every-day knocks. Regular calibration gives the following benefits: Assurance that the meter is still accurate. Most faults are repaired free of charge. The meter gets a full service, helping to prolong its life. Comes with battery and case. None. It’s expensive but competitively priced for an instrument of this quality. Best Bang for the Buck. RISEPRO. Decibel Meter. Check Price. Easy to Read.
